Daniel Edgar Sickles (October 20, 1819 – May 3, 1914) was an American politician, Civil War veteran, and diplomat. He served in the U.S. House of Representatives both before and after the war.

Key Information

Sickles was involved in a number of scandals, most notably the 1859 homicide of his wife's lover, U.S. Attorney Philip Barton Key II.[2] He was acquitted after using temporary insanity as a legal defense for the first time in United States history.

Early life and politics

[edit]

In 1819, Sickles was born in New York City to Susan Marsh Sickles and George Garrett Sickles, a patent lawyer and politician.[3] (His year of birth is sometimes given as 1825, and Sickles was known to have claimed as such. Historians speculate that Sickles chose to appear younger when he married a woman half his age.) He learned the printer's trade and studied at the University of the City of New York (now New York University).[4] He studied law in the office of Benjamin Butler, was admitted to the bar in 1843,[5] and was elected as a member of the New York State Assembly (New York Co.) in 1847.[3]

On September 27, 1852, Sickles married Teresa Bagioli against the wishes of both families—he was 32, she about 15 or 16.[6] She was reported as sophisticated for her age, speaking five languages.

Political office

[edit]

In 1853 Sickles became corporation counsel of New York City, but resigned soon afterward when appointed by President Franklin Pierce to be secretary of the U.S. legation in London. He served under United States Minister to the United Kingdom James Buchanan.[4]

In 1855 he returned to the United States, and in 1856 he was elected as a member of the New York State Senate in the 3rd district. He was re-elected to the seat in 1857.

In 1856 he was elected as a Democrat to the 35th U.S. Congress, and held office from March 4, 1857, to March 3, 1861, a total of two terms.[citation needed]

Sickles was censured by the New York State Assembly for escorting a known prostitute, Fanny White, into the Assembly's chambers. He also reportedly took her to England, while leaving his pregnant wife at home. He presented White to Queen Victoria, using as her alias the surname of a New York political opponent.[3]

Homicide of Philip Key

[edit]

On February 27, 1859, in Lafayette Square, across the street from the White House, Sickles shot and killed Philip Barton Key II, the United States Attorney for the District of Columbia[7] and the son of Francis Scott Key. Sickles had discovered that Philip Key was having an affair with his wife, Teresa Bagioli Sickles.[2][8]

Trial

[edit]
Main article: Trial of Daniel Sickles

"You are here to fix the price of the marriage bed!", roared Associate Defense Attorney John Graham, in a speech so packed with quotations from Othello, Judaic history and Roman law that it lasted two days and later appeared as a book.

Time article, "Yankee King of Spain", June 18, 1945[9]

Sickles surrendered at Attorney General Jeremiah Black's house, a few blocks away on Franklin Square, and confessed to the murder. After a visit to his home, accompanied by a constable, Sickles was taken to jail. He received numerous perquisites, including being allowed to retain his personal weapon, and receive numerous visitors. So many visitors came that he was granted the use of the head jailer's apartment to receive them.[10] They included many congressmen, senators, and other leading members of Washington society. President James Buchanan sent Sickles a personal note.[citation needed]

Harper's Magazine reported that the visits of his wife's mother and her clergyman were painful for Sickles. Both told him that Teresa was distracted with grief, shame, and sorrow, and that the loss of her wedding ring (which Sickles had taken on visiting his home) was more than Teresa could bear.[citation needed]

Sickles was charged with murder. He secured several leading politicians as defense attorneys, among them Edwin Stanton, later to become Secretary of War, and Chief Counsel James T. Brady who, like Sickles, was associated with Tammany Hall.[11] Sickles pleaded temporary insanity—the first use of this defense in the United States.[12] Before the jury, Stanton argued that Sickles had been driven insane by his wife's infidelity, and thus was out of his mind when he shot Key. The papers soon trumpeted that Sickles was a hero for "saving all the ladies of Washington from this rogue named Key."[13]

Sickles had obtained a graphic confession from Teresa; it was ruled inadmissible in court, but was leaked by him to the press and printed in the newspapers in full. The defense strategy ensured that the trial was the main topic of conversations in Washington for weeks, and the extensive coverage of national papers was sympathetic to Sickles.[14] In the courtroom, the strategy brought drama, controversy, and, ultimately, an acquittal for Sickles.[15]

Sickles publicly forgave Teresa, and "withdrew" briefly from public life, although he did not resign from Congress. The public was apparently more outraged by Sickles's forgiveness and reconciliation with his wife than by the murder and his unorthodox acquittal.[16]

Civil War

[edit]

In the 1850s, Sickles had received a commission in the 12th Regiment of the New York Militia, and had attained the rank of major.[17] He insisted on wearing his militia uniform for ceremonial occasions while serving in London, and caused a minor diplomatic scandal by snubbing Queen Victoria at an Independence Day celebration.[18]

At the outbreak of the Civil War, Sickles worked to repair his public image by raising volunteer units in New York for the Union Army. Because of his previous military experience and political connections, he was appointed colonel of the 70th New York Infantry, one of the four regiments he organized.[19] He was promoted to brigadier general of volunteers in September 1861, where he was notorious before beginning any fighting.

According to author Garry Boulard's Daniel Sickles: A Life, Sickles not only refused to return runaway slaves who escaped to his Union camp in Northern Virginia, he put many of them on the federal payroll as servants, while also training male slaves to be soldiers. It was a policy that won for him the approval of the influential Congressional Committee on the Conduct of the War.

Sickles in 1861.

In March 1862, he was forced to relinquish his command when the U.S. Congress refused to confirm his commission. He lobbied his Washington political contacts and reclaimed both his rank and his command on May 24, 1862, in time to rejoin the Army in the Peninsula Campaign.[3] Because of this interruption, Sickles missed his brigade's significant actions at the Battle of Williamsburg. Despite his lack of previous combat experience, he did a competent job commanding the "Excelsior Brigade" of the Army of the Potomac in the Battle of Seven Pines and the Seven Days Battles. He was absent for the Second Battle of Bull Run,[8] having used his political influences to obtain leave to go to New York City to recruit new troops. He also missed the Battle of Antietam because the III Corps, to which he was assigned as a division commander, was stationed on the lower Potomac, protecting the capital.[citation needed]

Sickles was a close ally of Maj. Gen. Joseph Hooker, his original division commander, who eventually commanded the Army of the Potomac. Both men had notorious reputations as political climbers and as hard-drinking ladies' men.

Sickles' division was in reserve at the Battle of Fredericksburg. On January 16, 1863, President Abraham Lincoln nominated Sickles for promotion to the grade of major general to rank from November 29, 1862.[20] Although the U.S. Senate did not confirm the promotion until March 9, 1863, and the President did not formally appoint Sickles until March 11, 1863,[20] Hooker, now commanding the Army of the Potomac, gave Sickles command of the III Corps in February 1863.

This decision was controversial as Sickles became the only corps commander without a West Point military education. His energy and ability were conspicuous in the Battle of Chancellorsville. He aggressively recommended pursuing troops he saw in his sector on May 2, 1863. Sickles thought the Confederates were retreating, but these turned out to be elements of Stonewall Jackson's corps, stealthily marching around the Union flank. He also vigorously opposed Hooker's orders moving him off good defensive terrain in Hazel Grove. In both of these cases, it is conceivable that the disastrous battle might have played out very differently for the Union if Hooker had heeded his advice.[21]

Gettysburg

[edit]

The Battle of Gettysburg was the occasion of the most famous incident and the effective end of Sickles' military career. On July 2, 1863, Army of the Potomac commander Maj. Gen. George G. Meade ordered Sickles' corps to take up defensive positions on the southern end of Cemetery Ridge, anchored in the north to the II Corps and to the south, the hill known as Little Round Top. Sickles was unhappy to see the "Peach Orchard," a slightly higher terrain feature, to his front.[22] Concerned over his position and uncertain of Meade's exact intentions, a little after 2 p.m. he began to march his corps out to the Peach Orchard, almost a mile in front of Cemetery Ridge.[23] This had two effects: it greatly diluted the concentrated defensive posture of his corps by stretching it too thin, and it created a salient that could be bombarded and attacked from multiple sides.

Soon thereafter (3 p.m.), Meade called a meeting of his corps commanders.[22] An aide to Brig. Gen. Gouverneur K. Warren soon reported the situation.[22] Sickles arrived just after the meeting had ended. Meade and Warren rode with Sickles back to his position, where Meade explained Sickles' error.[24] Meade refused Sickles' offer to withdraw because he realized it was too late[25] and the Confederates would soon attack, putting a retreating force in even greater peril.[22]

The Confederates attacked at about the time Meade spoke with Sickles and then returned to his headquarters.[24] The Confederate assault by Lt. Gen. James Longstreet's corps, primarily by the division of Maj. Gen. Lafayette McLaws, smashed the III Corps and rendered it useless for further combat. Gettysburg campaign historian Edwin B. Coddington assigns "much of the blame for the near disaster" in the center of the Union line to Sickles.[26] Stephen W. Sears wrote that "Dan Sickles, in not obeying Meade's explicit orders, risked both his Third Corps and the army's defensive plan on July 2."[27] However, Sickles' maneuver has recently been credited by John Keegan with blunting the whole Confederate offensive that was intended to cause the collapse of the Union line.[28] Similarly, James M. McPherson wrote that "Sickles's unwise move may have unwittingly foiled Lee's hopes."[25]

During the height of the Confederate attack, Sickles was wounded by a cannonball that mangled his right leg. He was carried by a detail of soldiers to the shade of the Trostle farmhouse, where a saddle strap was applied as a tourniquet. He ordered his aide, Major Harry Tremain, "Tell General Birney he must take command." As Sickles was carried by stretcher to the III Corps hospital on the Taneytown Road, he attempted to raise his soldiers' spirits by grinning and puffing on a cigar along the way.[29] His leg was amputated that afternoon. He insisted on being transported to Washington, D.C., which he reached on July 4, 1863. He brought some of the first news of the great Union victory, and started a public relations campaign to defend his behavior in the conflict. On the afternoon of July 5, President Lincoln and his son, Tad, visited General Sickles, as he was recovering in Washington.[30]

Sickles's leg, along with a cannonball similar to the one that shattered it, on display at the National Museum of Health and Medicine

Sickles had recent knowledge of a new directive from the Army Surgeon General to collect and forward "specimens of morbid anatomy ... together with projectiles and foreign bodies removed" to the newly founded Army Medical Museum in Washington, D.C. He preserved the bones from his leg and donated them to the museum in a small coffin-shaped box, along with a visiting card marked, "With the compliments of Major General D.E.S." Upon his first visit to the limb, Sickles allegedly berated the museum for not preserving his foot as well.[31] For several years thereafter, he reportedly visited the limb on the anniversary of the amputation. The museum, now known as the National Museum of Health and Medicine, still displays this artifact.

Sickles ran a vicious campaign against General Meade's character after Gettysburg. Sickles felt that Meade had wronged him and that he deserved credit for winning the battle. In anonymous newspaper articles and in testimony before a congressional committee, Sickles falsely maintained that Meade had secretly planned to retreat from Gettysburg on the first day.[32] He also claimed to have occupied Little Round Top on July 2.[33] While his movement away from Cemetery Ridge may have violated orders, Sickles always asserted that it was the correct move because it disrupted the Confederate attack, redirecting its thrust, and effectively shielding the Union's real objectives, Cemetery Ridge and Cemetery Hill.[34] Sickles's redeployment took Confederate commanders by surprise, and historians have argued about its ramifications ever since.

Sickles eventually received the Medal of Honor for his actions, although it took him 34 years to get it. The official citation accompanying his medal recorded that Sickles "displayed most conspicuous gallantry on the field, vigorously contesting the advance of the enemy and continuing to encourage his troops after being himself severely wounded."[35]

Postbellum career

[edit]

Despite his disability, Sickles remained in the army until the end of the war and was disgusted that Lt. Gen. Ulysses S. Grant would not allow him to return to a combat command. In 1867, he received appointments as brevet brigadier general and major general in the regular army for his services at Fredericksburg and Gettysburg, respectively.[4]

Soon after the close of the Civil War, in 1865, he was sent on a confidential mission to Colombia (the "special mission to the South American Republics") to secure its compliance with a treaty agreement of 1846 permitting the United States to convey troops across the Isthmus of Panama.[4]

From 1865 to 1867, he commanded the Department of South Carolina, the Department of the Carolinas, the Department of the South, and the Second Military District. Sickles pursued Reconstruction on a basis of fair treatment for African-Americans and respect for the rights of employees. He halted foreclosures on property. He also made the wages of farm laborers the first lien on crops. He outlawed discrimination against African-Americans and banned the production of whisky.[36]

In 1866, he was appointed colonel of the 42nd U.S. Infantry (Veteran Reserve Corps), and in 1869 he was retired with the rank of major general.[4]

Sickles served as U.S. Minister to Spain from 1869 to 1874, after the Senate failed to confirm Henry Shelton Sanford to the post, and took part in the negotiations growing out of the Virginius Affair. His inaccurate and emotional messages to Washington promoted war, until he was overruled by Secretary of State Hamilton Fish and the war scare died out.

In his Daniel Sickles: A Life Garry Boulard points out that Sickles was disadvantaged throughout the Virginius controversy, trying to negotiate with a Spanish leadership that was frequently disorganized and chaotic, while the substantial talks were taking place in Washington between Fish and Spanish Minister Don Jose Polo de Barnabe. Even so, when Sickles subsequently decided to turn in his resignation, Fish, who was not displeased with Sickles' service, wired the General: "You are recalled on your own request."[37]

Sickles maintained his reputation as a ladies' man in the Spanish royal court and was rumored to have had an affair with the deposed Queen Isabella II. Following the death of Teresa in 1867, in 1871 he married Carmina Creagh (or de Creagh), the daughter of French-born Chevalier de Creagh, of Madrid, a Spanish Councillor of State. They had two children.[38]

Starting in the 1880s and continuing until nearly the end of his life, Sickles frequently attended and spoke at Gettysburg reunions as the former commander of the III Corps in the victorious Army of the Potomac, popular with many of the veterans who had served under his command.[39] He also struck up a friendship with former opponent James Longstreet, one who was also seeking to defend himself from attacks – many politically motivated in Longstreet's case – over his performance in the war..[40]

Sickles' popularity with veterans was not universal, however, because of his inflated claims that he was the ultimate father of the Union victory and his repeated attacks against George Meade, even after Meade's death in 1872, with falsehoods about Meade wanting to retreat from Gettysburg.[41]

Excelsior Brigade monument at Gettysburg

The New York Monuments Commission was formed in 1886 and Sickles was appointed honorary chairman. He served the commission zealously for most of the rest of his life in securing appropriations for monuments to New York regiments, batteries, and commanders and having them placed correctly on the Gettysburg battlefield.[42] He was forced out of the Commission in 1912, however, when $27,000 was found to have been embezzled.[43]

Sickles was appointed as chairman of the New York State Civil Service Commission from 1888 to 1889, and Sheriff of New York County in 1890. In 1891, he was elected to the board of the Gettysburg Battlefield Memorial Association.[44] In 1892, he was elected again as a Democratic representative in the 53rd Congress, serving from 1893 to 1895.[45]

Sickles in 1911

As a congressman, Sickles had an important part in efforts to preserve the Gettysburg Battlefield, sponsoring legislation to form the Gettysburg National Military Park, buy up private lands, and erect monuments. He procured the original fencing used on East Cemetery Hill to mark the park's borders. This fencing came directly from Lafayette Square in Washington, D.C.[46] In fact, the park's borders were defined from its establishment until 1974 by a map prepared by Sickles.[47]

Of the principal senior generals who fought at Gettysburg, virtually all, with the conspicuous exception of Sickles, have been memorialized with statues. When asked why there was no memorial to him, Sickles supposedly said, "The entire battlefield is a memorial to Sickles." The monument to the New York Excelsior Brigade was originally commissioned to include a bust of Sickles, but it includes a figure of an eagle instead.[48]

Death

Sickles lived out the remainder of his life in New York City, dying of a cerebral hemorrhage on May 3, 1914, at the age of 94.[49] His funeral was held at St. Patrick's Cathedral in Manhattan on May 8, 1914. He was buried in Arlington National Cemetery.[50][35][51][52]

As a New York assemblyman and U.S. congressman, Sickles aligned with Democratic interests and navigated the city's networks before the war. In February 1859, he confronted and fatally shot , the U.S. and paramour of Sickles's wife , in broad daylight near the ; his subsequent trial ended in after defense attorneys successfully argued temporary insanity, establishing a for that plea in American jurisprudence.
Commissioned as a Union brigadier general despite lacking formal military experience, Sickles organized the Excelsior Brigade from New York recruits and rose to command the III Corps under the . His most notorious action came on July 2, 1863, at Gettysburg, where he disobeyed orders from Maj. Gen. George G. Meade to advance his corps from defensive positions along into the open salient, drawing Confederate assaults that inflicted devastating losses on his outnumbered forces—over 4,000 casualties—and culminated in Sickles's right leg being shattered by a cannonball, necessitating immediate field amputation.
After the war, Sickles managed Reconstruction duties in the , served as U.S. minister to from 1869 to 1873 amid personal scandals including an affair with Queen Isabella II, and later received the for gallantry near Chancellorsville. His impulsive decisions and personal indiscretions defined a legacy blending audacity with recklessness, influencing legal, military, and diplomatic spheres.

Early Life

Family and Upbringing

Daniel Edgar Sickles was born on October 20, 1819, in to George Garrett Sickles, a patent lawyer, , and real estate broker, and Susan Marsh Sickles, daughter of Gideon Marsh and Sarah Tucker. His parents' affluence as landowners afforded the family stability amid the city's rapid growth and political turbulence in the early . Sickles was reportedly the only child of George and Susan, raised in an environment shaped by his father's professional and political connections, which exposed him early to the machinations of and Democratic Party networks. Historical records provide scant details on his precise childhood experiences, though his upbringing in Manhattan's evolving urban landscape—marked by booms and immigrant influxes—likely instilled a pragmatic familiarity with power dynamics from a young age.

Education and Initial Career

Sickles received his early education in New York City public schools before, in 1838, being placed in the household of Lorenzo L. Da Ponte, a professor at , to prepare for college admission. He attended but did not complete a degree, instead apprenticing as a printer, which provided initial exposure to the publishing trade. Following this preparatory phase, Sickles studied law under , a prominent attorney with political connections, and was admitted to the New York bar in 1846. Upon gaining admission to the bar, Sickles established a private law practice in , focusing on civil and criminal cases amid the city's burgeoning legal environment. His early professional efforts were marked by ambitious networking rather than immediate prominence, as he leveraged personal charisma and —his father George Garrett Sickles also pursued law under Butler's influence—to build clientele. The practice yielded modest success but drew early scrutiny for ethically ambiguous dealings, including involvement in patronage networks that foreshadowed his political ascent. Concurrently, Sickles maintained ties to , occasionally dabbling in related ventures that supplemented his income during the late 1840s.

Pre-War Political Involvement

Rise in Tammany Hall

Sickles began his political involvement in 1844 by aligning with , the influential Democratic political organization that dominated governance through patronage, voter mobilization among immigrants, and control over party nominations. This affiliation provided entry into local politics for ambitious young Democrats like Sickles, who had apprenticed as a printer and attended before studying law. Admitted to the New York bar in 1846, Sickles established a legal practice in while actively participating in Tammany activities, including campaigning for Democratic candidates such as in the 1844 . His efforts within the machine's wards and committees positioned him for rapid advancement, as Tammany rewarded loyal operatives with endorsements that translated to electoral success in machine-controlled districts. By 1847, at age 27, Sickles secured election to the from New York County's 3rd District, a position secured through Tammany's organizational muscle and his own reputation for combative oratory, earning him the moniker "Devil Dan" among contemporaries. This early legislative role solidified his standing in Tammany circles, where he navigated the factional rivalries and graft typical of the era's urban machines, advancing through demonstrated loyalty and effectiveness in delivering votes. Sickles' ascent continued with patronage appointments, such as his 1853 role as secretary to the U.S. in under Democratic President , a post arranged via Tammany and national party connections that underscored the machine's reach into federal sinecures. Returning to New York, he leveraged these credentials for further elevation, reflecting Tammany's strategy of elevating reliable operatives to higher offices to maintain influence.

Elective Positions and Legislative Record

Sickles was elected to the , representing New York County, for the 1847 session as a Democrat aligned with . His legislative activity in the Assembly was limited, though he drew controversy for conduct unrelated to policy, including by members for escorting a known prostitute into the chamber during session. In 1855, following his return from a diplomatic post in , Sickles secured election to the , serving from 1856 to 1857. During this term, he delivered a notable speech opposing a favoring a bridge across the at Albany, arguing against the project's feasibility and potential interference with navigation. Sickles won election to the on November 4, 1856, as a Democrat from , taking office on March 4, 1857, for the 35th Congress; he was reelected on November 2, 1858, and served through the 36th Congress until March 3, 1861. As a partisan Democrat, he backed measures favoring Southern interests, such as compromises on expansion, in efforts to forestall sectional crisis and . In the 36th Congress, amid rising tensions, Sickles addressed the on the on December 10, 1860, and delivered a speech titled "The Revolution of 1860" on January 16, 1861, critiquing disunionist threats while urging preservation of federal authority. He also spoke on "New Phases of the Revolution—How to Meet Them," advocating pragmatic responses to Southern agitation without endorsing coercion.

The Philip Barton Key Scandal

Marriage and Adulterous Affair

Daniel Sickles married Teresa Bagioli, the daughter of his music teacher Antonio Bagioli, an Italian composer and immigrant, on September 27, 1852, in a civil ceremony conducted by James B. Taylor despite strong opposition from both families. At the time, Sickles was 26 years old and a rising politician, while Bagioli was approximately 16, having been educated in a sophisticated household that included the Da Ponte family, descendants of Mozart's librettist ; the union drew criticism for the age disparity and her youth, with some contemporaries viewing it as imprudent or scandalous. The couple had one child together, a daughter named Laura, born in July 1853. Sickles, himself a habitual womanizer with documented liaisons including prostitutes and other women during his political career in New York, frequently absented himself from home for business and personal pursuits, contributing to strains in the marriage. Beginning in the spring of 1858, Teresa engaged in an adulterous affair with Philip Barton Key II, a 42-year-old widower, attorney, and U.S. District Attorney for Washington, D.C., who was the son of Francis Scott Key, author of "The Star-Spangled Banner." Key, often called upon to escort Teresa socially during Sickles' extended trips to New York, rented a vacant house across from the White House in Lafayette Square for their clandestine meetings, where they conducted the relationship multiple times weekly; Teresa later detailed these rendezvous in a written confession, describing intimate encounters on a bed in the unoccupied property. The affair remained unknown to Sickles until February 1859, when he received an anonymous letter—likely from a suspicious neighbor or servant—alerting him to Key's frequent signals to using a spyglass from Lafayette Square and their assignations at the house. Confronted by her husband, admitted the under duress, providing a signed outlining the affair's duration, locations, and Key's role in initiating and sustaining it, which Sickles used to justify his subsequent actions while publicly framing Key as the seducer exploiting his wife's vulnerability. Despite Sickles' own history of marital unfaithfulness, the revelation intensified personal and public scrutiny on the couple's relationship, setting the stage for the ensuing legal confrontation.

Homicide and Immediate Aftermath

On February 27, 1859, U.S. Congressman Daniel E. Sickles fatally shot Philip Barton Key II, the U.S. District Attorney for the District of Columbia, in broad daylight in Lafayette Square, adjacent to the White House in Washington, D.C. Sickles had discovered Key's affair with his wife, Teresa Bagioli Sickles, and observed Key signaling to her from the street outside their residence using a string attached to her window. Armed with a single-shot Derringer and additional loaded firearms, Sickles confronted Key, who was standing near the square waving a handkerchief. Key reportedly pleaded, "Don't shoot," and attempted to flee toward a , but Sickles fired the first shot into his or chest area. As Key staggered, Sickles pursued and fired two more shots—one into Key's chest and another that struck his thigh—while a final attempt misfired. Key collapsed and died within minutes from blood loss and organ damage, witnessed by multiple bystanders including police officers. Immediately following the shooting, Sickles returned to his home briefly before proceeding to the , police headquarters, where he confessed to the act, stating he had killed Key for seducing his wife. He was arrested and charged with but released on $10,000 posted by prominent supporters, including fellow congressmen and Vice President . Public reaction largely favored Sickles, with crowds gathering to cheer him and viewing the killing as a justifiable defense of personal honor amid the era's strict codes on marital .

Trial, Insanity Defense, and Acquittal

The trial of Daniel Sickles for the of commenced on April 4, 1859, in the , Criminal Court, presided over by Judge Thomas H. Davidson, and drew immense public attention, with spectators overcrowding the courtroom daily. Sickles, represented by a prominent defense team including Edwin M. Stanton and James T. Brady, faced charges of premeditated based on his deliberate of weapons and confrontation of Key in Lafayette Square on February 27, 1859. The prosecution, led by U.S. and Key's brother-in-law Robert Ould, presented evidence of Sickles' prior knowledge of the affair, including an anonymous note received four days before the killing, arguing and rejecting claims of sudden provocation. The defense strategy centered on the novel plea of temporary insanity, positing that Sickles' discovery of his wife Teresa's adultery with Key induced a brief mental aberration rendering him incapable of rational control, marking the first successful application of this doctrine in U.S. . Over 20 days of , defense witnesses—including Sickles' mother, sister, and political allies—described his post-discovery symptoms of , rage, and as evidence of mental collapse, while medical experts debated the physiological effects of extreme emotional trauma on cognition. Sickles himself took the stand, confessing the shooting but attributing it to an uncontrollable impulse, a rare move that humanized his account and elicited sympathy from jurors attuned to codes of male honor amid revelations of Key's brazen seduction. Prosecutors countered by highlighting Sickles' composure in planning the act—arming himself with pistols and a —and his lack of prior mental instability, urging the to view the defense as a disguised justification for rather than genuine . Despite this, after eight hours of deliberation on April 26, 1859, the returned a of not guilty by reason of temporary , a decision influenced by widespread public approbation for Sickles' defense of marital fidelity, though critics later decried it as excusing premeditated homicide under the guise of emotional excuse. The established a legal , expanding insanity defenses to transient states but sparking enduring debate on for passion-driven crimes.

Civil War Service

Commission as Officer and Early Engagements

With the outbreak of the in April 1861, Daniel E. Sickles, leveraging his political influence as a New York assemblyman and associate, sought a military role despite lacking prior formal training or experience. On May 18, 1861, he received presidential authorization to recruit a of New York volunteers, which he organized at significant personal expense during the summer, naming it the Excelsior Brigade comprising the 70th, 72nd, 73rd, and 74th New York Infantry regiments. In June 1861, Sickles was commissioned as colonel of the 70th New York Infantry, assuming command of the initial regiment within his brigade. By September 3, 1861, he received promotion to brigadier general of volunteers, one of many political appointments by President Lincoln to secure loyalty from key Northern states, though his selection drew criticism for prioritizing connections over military qualifications. The Excelsior Brigade mustered into federal service in July 1861 and joined the , with Sickles retaining command amid tensions with New York Governor , who initially resisted the unit's formation outside state control. Sickles' early field engagements occurred during the of 1862, where the Excelsior Brigade, under his leadership, participated in the Siege of Yorktown (April-May 1862) and the (May 5, 1862). The brigade saw its first major combat at the (May 31-June 1, 1862), holding defensive positions against Confederate assaults and suffering approximately 300 casualties, with Sickles coordinating movements to support Union lines under Maj. Gen. Edwin V. Sumner. During the subsequent (June 25-July 1, 1862), Sickles commanded the brigade in defensive actions at Savage's Station (June 29) and Glendale (June 30), where it repelled repeated Confederate attacks, incurring heavy losses—over 400 killed, wounded, or missing—while contributing to the stabilization of Maj. Gen. Hooker's division. These engagements marked Sickles' initial tests, demonstrating organizational effectiveness in maneuver and resilience under fire, though subordinates noted his reliance on aggressive, politically motivated tactics rather than doctrinal precision.

Build-Up to Gettysburg

Sickles received promotion to of volunteers on November 29, 1862, with U.S. Senate confirmation on January 16, 1863. In February 1863, commander , a personal friend, appointed him to lead the III Corps, numbering approximately 18,000 men and comprising divisions under , Charles K. Graham, and . This command reflected Sickles' political influence more than prior military experience, as he was the highest-ranking non-academy graduate in the army. The III Corps under Sickles joined the Chancellorsville campaign, departing Falmouth, Virginia, on April 30, 1863, and reaching the battlefield area by May 1. Positioned on the Union left flank near the Rappahannock River, the corps conducted reconnaissance of Confederate positions amid reports of enemy movements, though it saw limited initial action amid the fog of Hooker's divided command structure. On May 3, as Confederate forces under Stonewall Jackson counterattacked, III Corps elements fought defensively around Chancellorsville, helping to cover the Union retreat after Hooker's incapacitation and the failure to exploit early gains; casualties for the corps totaled around 1,200. The campaign ended in Union withdrawal by May 6, with Sickles' performance earning praise for energy despite the defeat, though critics later noted his corps' positioning contributed to vulnerabilities on the left. Following Chancellorsville, the reorganized under Hooker, who retained command amid Lee's Pennsylvania invasion starting late June 1863. Sickles' III Corps, weakened by losses and reinforcements, marched northward from in pursuit, crossing the around June 25–26 near Edwards Ferry, , as part of the army's 95,000-man force. Delays in coordination plagued the advance; Sickles' corps lagged behind schedule on June 29 near , prompting Hooker to relieve himself and leading to George G. Meade's appointment on June 28. By early July, the corps concentrated near Taneytown, , before advancing to Pipe Creek positions south of Gettysburg, arriving piecemeal on July 1–2, 1863, after I and XI Corps had engaged Confederates north of the town. This positioning placed III Corps in reserve for the defensive line along , setting the stage for its role on July 2.

Actions at Gettysburg and Strategic Decisions

On July 2, 1863, the second day of the , Daniel E. Sickles commanded the Union III , positioned on the southern end of the Union line along . General George G. Meade, the commander, issued explicit orders for Sickles to deploy defensively along the Emmitsburg Road, with the corps' left flank refused to connect with Hancock's II and the right anchoring on to link with V , emphasizing a compact formation to maintain the integrity of the main defensive line. These instructions were communicated multiple times through staff officers and aides, underscoring the need to hold the assigned ground without advancing. Sickles, however, assessed the ordered position as untenable due to its low elevation, obstructed fields of fire from stone walls and woods, and vulnerability to enfilading Confederate artillery, drawing parallels to perceived failures at Chancellorsville. He decided to advance the corps approximately three-quarters of a mile forward to higher ground at , located at the junction of the Emmitsburg and Wheatfield Roads, believing this salient would provide superior observation, artillery placement, and a preemptive denial of the terrain to approaching Confederate forces under Lieutenant General . This maneuver extended the corps' line by about 50 percent, divided its divisions under Major Generals and , and initially left unoccupied. Despite dispatching multiple aides to Meade for clarification or approval—including requests to adjust the position—Sickles proceeded with the advance without receiving authorization, interpreting the orders as insufficiently specific or adaptable to the terrain. He positioned artillery batteries prominently in the orchard to enfilade potential Confederate approaches and instructed his infantry to hold the forward line, anticipating it would force Longstreet's corps into premature engagement while buying time for reinforcements. The strategic decision has fueled the Meade-Sickles controversy, with Sickles later asserting that his initiative absorbed the Confederate assault, revealed enemy intentions, and preserved the Union flank, famously declaring the battlefield his monument. Contemporary and historical analyses, however, characterize the advance as against clear directives, creating an exposed salient susceptible to converging attacks and necessitating emergency shifts by adjacent , though some contend the terrain's tactical merits partially justified the risk.

Wounding, Casualties, and Tactical Outcomes

During the afternoon of July 2, 1863, at the , Daniel E. Sickles was severely wounded while directing operations from an exposed position near the Trostle Farm. A Confederate 12-pound solid shot cannonball struck his right leg just above the knee, shattering the bone and necessitating immediate field by Surgeon Thomas Sims, the III Corps Medical Director. Sickles remained conscious throughout the procedure, reportedly smoking a and cheering on his men afterward, before being evacuated to a Washington, D.C., the following day. The III Corps, numbering approximately 10,691 effectives at the battle's outset, suffered devastating losses under Sickles' command, with 4,211 casualties—including killed, wounded, and missing—representing nearly 40 percent of its strength. This toll stemmed from the corps' forward deployment into a vulnerable salient encompassing , Wheatfield, and , where it bore the brunt of James Longstreet's assaulting divisions. Tactically, Sickles' unauthorized advance created a protruding line that initially disrupted Confederate momentum by compelling Longstreet's forces to engage piecemeal rather than executing a swift en echelon assault on the Union left flank along . The resulting fierce combat in the salient bought critical time for Union V under Major General and elements of VI to reinforce the sector, ultimately stabilizing the line after III ' near-collapse. However, the maneuver exposed Sickles' flanks, fragmented his units, and rendered the corps combat-ineffective for the battle's remainder, with critics arguing the original defensive position offered superior natural cover and support without such disproportionate sacrifice. Sickles later contended his initiative seized commanding ground and alerted Meade to the threat, though postwar analyses emphasize the advance's pyrrhic nature in preserving the Union's tactical posture.

Post-Gettysburg Commands and War's End

Following the amputation of his right leg on July 2, 1863, during the , Daniel Sickles was evacuated to a and then transported to , arriving by July 4 to brief authorities on the Union's tactical success despite heavy III Corps losses. His severe wounding ended his direct field leadership of the III Corps, which was temporarily placed under before reorganization under other commanders in the Army of the Potomac's subsequent campaigns. Despite equipping himself with a prosthetic and aggressively for reinstatement to combat duty, Sickles was barred from further field commands by Lieutenant General , primarily due to concerns over his and its impact on operational effectiveness. He remained on the army's active roster in a non-combat capacity, conducting administrative and observational roles without assignment to brigade, division, or corps-level responsibilities amid the Overland Campaign, Petersburg Siege, and Appomattox operations from 1864 to April 1865. Sickles' military tenure concluded with the Confederate surrender at Appomattox Court House on , 1865, after which he transitioned to post-war duties, including a confidential to later that year to secure U.S. transit rights across the under an 1846 treaty. In 1867, awarded him retrospective brevets to , U.S. , for Fredericksburg, and major general, U.S. , for Gettysburg, acknowledging his earlier contributions despite the absence of late-war commands.

Military Honors and Controversies

Medal of Honor Nomination and Award

Sickles received the on October 30, 1897, recognizing his actions as a major general commanding the III Corps during the on July 2, 1863. The award was presented for service in the U.S. Army Volunteers, with the official citation stating: "Displayed most conspicuous gallantry on the field vigorously contesting the advance of the enemy and continuing to encourage his troops after being himself severely wounded." This honored his leadership amid heavy fighting along the Union left flank, where he directed operations from a forward position until struck by a cannonball that necessitated leg amputation. The issuance followed initial post-war denials of Sickles' efforts to obtain it, occurring 34 years after the engagement. Unlike many Civil War medals awarded contemporaneously or shortly thereafter, Sickles' recognition aligned with a period of retrospective honors for Union officers, processed through congressional and review. No specific nomination date prior to 1897 is documented in official records, though the delay reflected broader scrutiny of Gettysburg command decisions. The medal, an early version of the Army design, underscored valor in contesting Confederate advances despite personal injury.

Historical Debates on Merit and Political Influence

Sickles was awarded the on October 30, 1897, with the citation recognizing his "most conspicuous gallantry on the field vigorously contesting the enemy's forces in the , Pa., and holding the ground occupied after his leg was shattered by a shell." This honor, bestowed 34 years after the battle, highlighted his personal bravery in remaining on the field after sustaining a grievous from a cannonball that necessitated of his right leg on July 2, 1863. However, the award's timing and focus on individual resilience amid broader tactical controversy have prompted debates over whether it truly reflected strategic merit or was swayed by Sickles' post-war advocacy. Historians critical of Sickles' Gettysburg performance argue that his unauthorized advance of the III Corps approximately 0.75 miles forward from its assigned position along to the Emmitsburg Road and line constituted a profound error, exposing roughly 10,000 men to enfilading Confederate artillery and infantry under Lt. Gen. , resulting in over 4,200 casualties—nearly 40 percent of the corps' strength—and the near-destruction of the unit. Maj. Gen. George G. Meade, Sickles' superior, explicitly faulted the move in official reports for disobeying orders to anchor the Union left flank near , creating a vulnerable salient that required emergency reinforcements from V Corps and nearly collapsed the defensive line before nightfall. Such assessments, echoed by scholars like Edwin B. Coddington, portray Sickles' decision as a leadership failure driven by terrain dissatisfaction and overambition rather than sound judgment, questioning the Medal of Honor's applicability to an action deemed tactically ruinous despite incidental strategic benefits, such as diverting Confederate focus. Defenders, including some veterans and later analysts, maintain that Sickles' initiative seized preemptively, disrupted Longstreet's timetable, and inflicted significant enemy losses, thereby contributing to the Union's defensive success on by forcing Confederate adjustments and buying time for reinforcements. Yet, even supportive views often concede the disproportionate cost to III , with the medal's emphasis on post-wounding tenacity suggesting recognition of valor under fire over command efficacy. The delayed conferral of the award has intensified scrutiny of political factors, given Sickles' career as a Tammany Hall Democrat with ties to Abraham Lincoln and influential New York networks that facilitated his rapid wartime promotions despite limited prior military experience. Post-war, as chairman of the New York Monuments Commission from 1886, Sickles actively shaped Gettysburg's commemorative landscape by advocating for markers at his advanced positions, embedding his narrative of heroism in public memory and testifying before Congress to claim credit for averting defeat. Critics contend this lobbying, leveraging his congressional service (1857–1861, 1893–1895) and diplomatic role as U.S. Minister to Spain (1869–1873), elevated a contested legacy to national honor, exemplifying Gilded Age tendencies where personal connections influenced military accolades more than unvarnished battlefield outcomes. While no direct evidence of impropriety in the 1897 award exists, the absence of contemporaneous recommendation—unlike peers honored promptly—underscores perceptions of favoritism in an era when political veterans often secured retroactive validations.

Post-War Public Service

Diplomatic Role in Spain

Following his retirement from the U.S. Army in 1869, President appointed Daniel Sickles as Minister to in May of that year. Sickles presented his credentials on , 1869, and served until tendering his resignation on December 7, 1873, amid escalating tensions over the Cuban . His appointment came after the U.S. rejected the nomination of Henry Shelton Sanford, positioning Sickles to represent American interests during a turbulent period in Spanish history marked by the aftermath of the 1868 , the brief reign of King Amadeo I (1870–1873), and the onset of the . Sickles' primary diplomatic responsibilities involved reporting on Spain's internal instability and its suppression of the Cuban insurrection, which had erupted in October 1868 as rebels sought from colonial rule. He drafted multiple dispatches to detailing Spanish military efforts in , the inefficiencies of Madrid's response, and the potential for U.S. intervention if atrocities continued, including a notable 1869 note urging to address American concerns over filibustering and neutral rights violations. Sickles expressed sympathy for the Cuban cause, privately advocating that the insurgents warranted due to 's inability to quell the effectively, though his public communications emphasized diplomatic pressure rather than overt support. A key episode during his tenure was the of October–November 1873, in which Spanish forces in seized the American-flagged filibuster ship Virginius, executing fifty-three crew members, including U.S. citizens, for alleged and insurgent activities. Sickles conveyed urgent protests to the government, contributing to negotiations that averted war but resulted in the ship's release and reparations, highlighting the fragility of U.S.- relations over . His reports underscored Madrid's overextension, with committing over 100,000 troops to by 1873 at great fiscal cost, yet failing to achieve decisive victories. On a personal level, Sickles married Carmina de Creagh, the daughter of a Spanish chamberlain and significantly younger than himself, in 1871 while stationed in ; the union produced children but proved contentious, with Sickles later separating from her upon his return to the . Unverified rumors persisted of an extramarital involvement with the exiled Queen , whom Sickles reportedly encountered in after her 1868 abdication, though no contemporary evidence substantiates these claims beyond gossip in diplomatic circles. Sickles' tenure yielded no landmark treaties or policy shifts but provided the Grant administration with critical intelligence on Iberian affairs, aligning with broader U.S. interests in hemispheric stability and autonomy without direct military entanglement.

Return to Congress and Policy Positions

After serving as U.S. Minister to from 1869 to 1873, Daniel Sickles resumed his political career and was elected as a Democrat to represent in the on November 8, 1892, taking office on March 4, 1893. He served one term until March 3, 1895, leveraging his Civil War reputation among veterans and supporters despite his advanced age of 73 at the start of the term. During this congressional tenure, Sickles focused on , advocating for expanded pension benefits and reforms to the Pension Bureau to address delays and inadequacies in payments to former Union soldiers. He emphasized the nation's ongoing obligation to Civil War veterans, arguing that full recompense for their service remained unpaid and criticizing bureaucratic inefficiencies that left deserving claimants underserved. As a Democrat aligned with urban machine , Sickles generally opposed high protective tariffs favored by Republicans, supporting instead revenue-focused measures that aligned with party efforts to reduce duties during the 1894 Wilson-Gorman Tariff Act debates, though his specific votes reflected a pragmatic emphasis on constituency needs over ideological purity. Sickles played a pivotal role in battlefield preservation, sponsoring and advocating for legislation that established the Gettysburg National Military Park on February 11, 1895, near the end of his term. Drawing on his experience as III Corps commander at Gettysburg, he pushed for federal protection of the site to honor Union sacrifices and prevent commercial encroachment, collaborating with veterans' groups and state commissions to secure funding and authority for monument placement and land acquisition. This effort extended his pre-congressional work as chairman of the New York Monuments Commission, where he had already funded memorials like the Excelsior Brigade monument on the field. His advocacy underscored a commitment to commemorating military history without partisan revisionism, prioritizing empirical preservation of terrain and events over contemporary debates about tactical outcomes.

Contributions to Reconstruction and National Parks

In 1865, President appointed Sickles as military commander of the Department of the Carolinas, tasking him with overseeing the transition from wartime occupation to civilian governance amid ongoing tensions over freedmen's rights. During his tenure, Sickles issued orders establishing military commissions to try civilians for violations of , including crimes against , and permitted freedmen to serve on juries, measures aimed at enforcing equal protection under military authority but which provoked backlash from resistant to Radical Reconstruction policies. His public advocacy for stricter enforcement against former Confederates and support for black civil rights led to his removal by Johnson on August 26, 1866, amid the president's disputes with congressional Radicals; nonetheless, Sickles continued to promote fair treatment for freed slaves through assessments of slavery's impacts and recommendations for postwar reforms, including protections for African American labor and political participation. Following his military service in the , Sickles advocated for black rights in New York, supporting legislative initiatives to enhance opportunities for the state's African American population during the late and . His Reconstruction-era efforts reflected a commitment to integrating freedmen into society, though limited by his brief command and subsequent political shifts under Johnson's leniency toward the . Sickles played a pivotal role in the preservation of Civil War battlefields, particularly as a driving force behind the creation and development of Gettysburg National Military Park. As a U.S. Representative from New York (1893–1895), he sponsored and advocated for the congressional bill enacted on February 11, 1895, establishing the park to commemorate the 1863 battle, including provisions for federal acquisition of private lands and monument erection. In this capacity, Sickles chaired the New York State Monuments Commission, overseeing the placement of over 1,000 markers and statues highlighting Union, especially New York, contributions at Gettysburg, and he personally procured original fencing from East Cemetery Hill to define park boundaries.
His repeated visits to the site—spanning decades until 1913—facilitated land acquisitions and infrastructure like avenues named after his commands, ensuring the battlefield's integrity as a national memorial despite his controversial wartime tactics there. Sickles' preservation work extended the federal model of military parks initiated at Chickamauga in 1890, emphasizing historical accuracy and veteran commemoration over commercial development.

Later Years and Assessments

Family Dynamics and Personal Character

Daniel Sickles married Teresa Bagioli, the daughter of an Italian music instructor, in a civil ceremony on September 17, 1852, when he was 32 years old and she was approximately 15 or 16; the union defied objections from both families due to the significant age disparity and social improprieties, prompting a subsequent church wedding after her parents relented. The couple's only child, Laura Buchanan Sickles, was born in 1853, seven months after their marriage. Sickles, known for his own extramarital affairs, relocated the family to Washington, D.C., in 1856 amid his rising political career. The marriage unraveled publicly in 1859 when Sickles discovered Teresa's affair with Philip Barton Key II, son of "The Star-Spangled Banner" author Francis Scott Key and U.S. Attorney for the District of Columbia; on February 27, 1859, Sickles confronted and fatally shot Key multiple times in Lafayette Square near the White House, an act witnessed by several onlookers. During the ensuing trial, which drew national attention as the first U.S. case to successfully invoke temporary insanity as a defense, Sickles publicly professed forgiveness toward his wife, yet testimony revealed his prior infidelities and the couple's strained relations, with the prosecution framing the killing as premeditated despite the defense's emphasis on uncontrollable rage. Acquitted on April 26, 1859, Sickles faced no punishment, though the scandal shifted public scorn toward Teresa, portraying her as the primary moral transgressor in media accounts. Post-trial, the Sickles marriage persisted in name but grew deeply estranged, with Sickles providing financial support yet maintaining emotional and physical distance from , who retreated from society amid reputational damage. died of on October 7, 1867, at age 31 in , leaving Sickles a widower who did not remarry and focused subsequent years on and rather than family reconstruction. Their daughter Laura's life remained largely private, overshadowed by the parental scandals, with no records indicating Sickles' active involvement in her upbringing after the family disruptions. Sickles' personal character, as evidenced by his family conduct, blended political ambition and charisma with impulsivity and moral inconsistency; contemporaries and biographers describe him as a scheming operative prone to scandals, including unpaid debts and serial romantic entanglements, yet resilient in leveraging crises for advancement, such as turning the Key murder into a sympathetic narrative of betrayed honor. His jealousy-fueled violence contrasted with his own womanizing—exemplified by escorting prostitutes to public events—revealing a hypocritical streak amid a reputation for toughness and self-serving opportunism that permeated both private and public spheres. Despite these flaws, Sickles demonstrated tenacity, rebuilding his career post-scandal without evident , traits that underscored his unorthodox navigation of 19th-century social norms.

Overall Legacy: Achievements Versus Criticisms

Daniel Sickles' legacy endures as a polarizing blend of bold initiative and reckless indiscretion, marked by substantive contributions to Union victory preservation alongside persistent critiques of his tactical decisions and personal conduct. His for veterans' monuments and the establishment of in 1895, through sponsorship of enabling legislation and securing federal funding, preserved the battlefield as a site of historical commemoration, influencing subsequent developments. This effort reflected a commitment to honoring Civil War sacrifices, as evidenced by his role in funding monuments for Union forces, which countered the era's neglect of battlefield sites. Militarily, Sickles received the Medal of Honor in 1897 for "most gallant and meritorious conduct" at Gettysburg on July 2, 1863, where he advanced his III Corps to higher ground despite ambiguous orders, arguably disrupting Confederate momentum by engaging Longstreet's assault early and inflicting significant enemy losses before his own line collapsed. Proponents, including some contemporaries, credited this with buying critical time for reinforcements, though the award's timing—decades later amid his lobbying—fueled perceptions of political favoritism over battlefield merit. His pre-war acquittal in the 1859 murder of Philip Barton Key II, leveraging the novel temporary insanity defense, demonstrated legal audacity but underscored ethical lapses, as Sickles admitted to prior knowledge of the affair yet proceeded to fatal confrontation. Criticisms dominate historical assessments of Sickles' generalship, particularly his unauthorized forward deployment at Gettysburg, which exposed his flanks, abandoned prepared defenses, and resulted in over 4,200 casualties for III Corps—nearly half its strength—while necessitating Meade's diversion of reserves to stabilize the line. Lacking formal training, Sickles ascended through political connections in , a machine rife with graft allegations, leading detractors to portray him as emblematic of amateurism undermining professional command structures. Post-war scandals, including unpaid debts and financial improprieties during veterans' advocacy, eroded his stature, with contemporaries decrying his opportunism over principled service. Ultimately, Sickles' achievements in site preservation and veteran support offer tangible legacies that transcend his era's chaos, yet they are inextricably linked to criticisms of and that historians, drawing from primary accounts like Meade's reports, substantiate as causal factors in unnecessary Union losses and personal discredit. This duality—effective in advocacy, flawed in execution—positions him as a cautionary figure in Civil War historiography, where empirical casualty data and order-of-battle analyses outweigh revisionist defenses rooted in his self-justifications.

Death and Burial

Daniel Edgar Sickles died on May 3, 1914, at the age of 94 in from a cerebral hemorrhage. His funeral took place on May 8 at St. Patrick's Cathedral, featuring full military honors and a cortege that processed up amid large crowds paying respects. Sickles was interred at in Section 3.
