The Bergmann Offensive (Turkish: Bergmann Taaruzu; in Turkish literature Köprüköy ve Azap Muharebeleri, "Battles of Köprüköy and Azap"; in Russian literature Кёприкейская операция—"Köprüköy operation") was the first engagement of the Caucasus campaign. The first battle after the Russians took Bayazıt during World War I.[7] General Georgy Bergmann, commander of the 1st Caucasus Army Corps, took the initiative against the Ottoman Empire.

When the war started, Russia had 25 battalions at Sarikamish, 8 battalions at Oltu, 5 battalions at Kağızman and 5 battalions at Kars. Russia also had 20 cavalry companies.[8] On the other hand, the Ottomans had XI Corps' 2 divisions (18 Battalions) at Hasankale, IX Corps' 28th and 29th Divisions at Erzurum, IX Corps's 17th Division at İspir, XI Corps' 33rd Division at Tutak, 37th Division (6 battalions) at Muş, X Corps' 30th Division at Sivas, 32nd Division at Samsun and 31st Division at Amasya. X Corps didn't participate in the Bergmann Offensive due to its distance. 29th, 33rd and 37th Divisions joined the battle on 11 November and 17th Division on 17 November. The Ottomans initially had a 33% infantry numerical advantage (the Russian Caucasian Army consisted of 45,000 infantry and the Ottoman army had 60,000 infantry available) and Russia separated their army carelessly. The Ottomans however didn't use this advantage due to their precaution. Russia equalized numbers by starting to bring in the Turkistan Army Corps on 16 November. The Ottomans obtained a 50% infantry advantage by bringing X Corps (40,000 infantry) at the beginning of December.[9] This numerical superiority encouraged the Ottomans to perform the Sarikamish Offensive.

At the outbreak of war, the Russians decided to occupy the Eleşkirt valley as a defensive measure to prevent the incursion of Kurdish Hamidiye units. The Russians considered the Turkish forces to be too weak to mount any offensive before winter weather would make any such offensive impossible, and no other offensive moves were intended by the Russian high command of the Caucasian army – their strategy envisaged an active defense against a locally superior force. However, local Russian commanders had the authority to authorize limited advances.[10]

On 2 November, Bergmann's troops crossed the border in the general direction of Köprüköy. The primary aim was to secure the Eleșkirt valley. On the right flank, 20th Infantry Division under Istomin moved from Oltu in the direction of İd.[11] On the left flank a Cossack division under Baratov moved into the Eleșkirt valley towards Yuzveran, after it crossed the Aras River.[11]

By 5 November Bergmann had completed the objectives expected of him. However, he expanded his mission by ordering further advances into Ottoman territory. By 6 November contact was made between the opposing armies, and heavy fighting continued into the 7th, with temporary Russian successes. Further Russian advances were held in check as a result of heavy fighting between 7 and 10 November. On 11 November Ottoman forces counterattacked and the Russian flanks quickly became at risk, forcing a Russian retreat. By the 12th they had retreated back to the lines they occupied on the 4th, and still at risk of being outflanked, further retreats followed. Only the arrival of Russian reinforcements headed by General Przevalski checked the situation and halted the Russian retreat. On 16–17 November Przevalski crossed the Aras river and at dawn attacked part of the Turkish XI Corps, halting their advance. After two more days the fighting finally petered out.[12]

Russian losses were 1,000 killed and 4,000 wounded, 1,000 men died of exposure[6](with the Bakinski regiment suffering 40% losses), while the Ottomans lost 1,983 men killed, 6,170 wounded, 3,070 were taken prisoner, and 2,800 deserted.[6] Yudenich and his staff were disappointed by the unsuccessful attack. Turkish forces then crossed the border and, advancing into the lower Choruh valley, destroyed on 15 November a Russian column sent to protect the copper mines at Borçka, forcing the Russians to evacuate Borçka, Artvin and Ardanuç.[13] Turkish success during these first engagements encouraged Enver Pasha in his plan to attack at Sarıkamıș.[11][14]

Muratoff and Allen describe Bergman as "an officer who liked to imitate in appearance and manner the type of the old Caucasian hero-leaders", but who had "none of the qualities which are necessary as a commander; he had no experience of field operations, and was merely blindly obstinate when he thought to show strength of character".[15]

Turks had 227 thousand men (At the time, Turk Army tend to have available soldiers 70% of sum (160,000) approximately) on paper but Turk lost huge number of their troops due to illness, frostbite and desertion before reaching battlefield. 34th Division of 11th Corps had initially 12,000 men but Commander of 34th Division Ali İhsan Pasha could bring only 8,000 men. 33rd Division (initial number isn't mentioned in sources but it is close to 34th Division) decreased to 3,000 soldiers. At the beginning of the Battle of Sarikamish, Turkish forces was 90,000 soldiers. 40,000 soldiers came from 10th Corps. 9th Corps was 28,000 and 11th Corps 22,000 soldier. 13th Corps came from Baghdad and it could bring only 2,000 soldiers. 37th Division was sent to Bayazit against Oganovski's forces. Considering Turkish losses was 11,800 in Bergmann Offensive, We can estimate that Turkish Army was 62,000 soldiers in Bergmann Offensive. As for Russian side, Muratoff and Allen gave vague numbers. They said that "at an average of 1000 men per battalion, Caucasian Army amounted to about 100,000 infantry, 15,000 cavalry (117 sotni) and 256 guns".[16] Muratoff and Allen also said that Plastun (3 Plastun Brigade: 18 battalion) and Turkistan battalions (21 Battalions) was rarely above 800 men and 39th and 20th (16 battalions both) infantry division, after mobilization, became 25-30% above normal strength. Amount of normal strength isn't mentioned but it is probably 1000 men. In Bergmann Offensive, initially Russian had 39th, 20th Divisions (40,000-42,000 infantry), 5 Battalions of 1st Plastun Brigade (3,500 infantry) and 36 sotni (4,000 cavalry) and 120 guns. On the 15th, 4th Turkistan Rifle Brigade arrived. Strength of 4th Turkistan Rifle Brigade isn't mentioned by Muratoff and Allen but it constituted half of the Turkistan Army Corps (21 battalions, 42 guns).

In conclusion, Russians started battle with 45,000 infantry, 4,000 cavalry and 120 guns. They gained 7–8,000 strong reinforcement on 15 November. On the other hand, Turkish 17th Division caught Battle on 17 November. Consequently, both side had approximately 50,000 soldiers with equal gunpower (120 Russian guns against 128 Turkish guns).

From Turkish Side

[edit]

On 1 November, Russians crossed the border and started the move on Erzurum. The Ottoman frontier guards couldn't detect the power of the Russian forces because they were killed, routed or captured abruptly by Russians.[17] 3rd Army commander Hasan İzzet Pasha assumed that a Russian offensive with superior forces had started. He ordered XI Corps to retreat Erzurum without learning the magnitude of the Russian army. XI Corps retreated hastily to Erzurum in two days. Hasan İzzet Pasha sent 2nd Cavalry Division (1300 swords) to reconnoitre. On 4 November, Cavalry Division's commander lieutenant colonel Yusuf İzzet fought against Russian troops successfully in Köprüköy village.[17] On the same day, Enver Pasha recommended Hasan İzzet to attack and annihilate separately moving Russian troops. Because of this, Hasan İzzet Pasha underestimated the Russians and sent back XI Corps in a similar hurry. On 6 November, Cavalry Division again battled Russian troops in Köprüköy and retreated.[18] It was observed the Russians as 8 infantry battalions and one cavalry regiment.

Hasan İzzet planned to rout this vanguard force and retreat again to the Erzurum fortifications. 7 November was a rainy and foggy day. Two divisions of XI Corps moved from Hasankale. The Russians were supposed to be east of Köprüköy, but they came to Badicivan village 10 kilometers northwest of Köprüköy. One regiment of XI Corps fell into heavy Russian rifle and artillery fire. This regiment started to escape disorderly and panic passed to other Ottoman troops. All XI Corps ran off to Hasankale. Ottoman officers regrouped XI Corps before long and sent back them to the Russians, but in this day, the Ottomans couldn't make any progress. On the second day the Ottomans forced the Russians to retreat from their forward trenches. After the Ottoman victory of 8 November, Hasan İzzet's German chief of staff, Lieutenant Colonel Felix Guse, said to Hasan İzzet: "The best retreat is retreat after gaining success. We have been successful... If Russia attacks us with superior forces, it will be hard to hold in these trenches and retreat to Erzurum". Hasan İzzet accepted Guse's proposal and ordered to write a retreat decree. XI Corps commander Galip Pasha said "I will resign if this decree applies. There is no reason for retreat. This decision demoralizes our soldiers". This decree was cancelled and the next day more positions were captured.[19] Battles continued until 21 November. In the following days, The Ottomans tried to encircle the Russians with 29th Division in the north and 33rd Division in the south. On 17 November, 33rd Division was just 3,000 soldiers strong, and was defeated by Przevalski's superior forces. 29th Division coincided inconvenient terrain; accordingly, they were stopped easily by the Russians. Also 29th Division didn't move away much from its main army. In fact, Hasan İzzet make encirclement on paper for convincing Enver.

Willing Retreat

[edit]

On 21 November, the Ottomans regained 30 kilometers but Hasan İzzet decide to retreat 15 kilometers as he had received exaggerated information about Russian troops toward Narman. He withdrew all armies on the night of 21 November. A terrible blizzard showed up. Hundreds of soldiers died from hypothermia and presence of Ottoman troops decreased by 50%. Russia didn't anticipate the Ottomans would retreat, because the Ottomans had successfully fought for 2 weeks. Ziya Yergök said: "If Russia would make use of this retreat, they could capture all our army with just one cavalry division". IX Corps commander Ahmet Fevzi Pasha criticized Hasan İzzet for this unnecessary retreat. Hasan İzzet Pasha wanted approval from Enver Pasha to dismiss of Ahmet Fevzi Pasha by making the argument that "Although he is commanding one of the most privileged Corps of 3rd Army, he is pessimistic about the result of the war". Enver Pasha gave the approval and Ahmet Fevzi Pasha was both dismissed and retired. 34th Division commander Ali İhsan Pasha was appointed IX Corps commander by Hasan İzzet Pasha. This retreat caused intrigue against Hasan İzzet Pasha. Enver Pasha wanted to see the situation on the scene. The council of ministers suggested that he should stay in Istanbul and send a proxy in his place, as he was minister of war and vice-generalissimo. Enver Pasha sent second chief of staff Hafiz Hakki Pasha instead of himself, but a few days later he also went to the Ottoman 3rd Army. This arrivals led to Sarikamish outflanking manoeuvre and pitched battle.

Bergmann Offensive

from Grokipedia
The Bergmann Offensive, also known as the Köprüköy operation, was the inaugural military engagement of the during , launched by the against the on 2 November 1914. Commanded by General Georgy Bergmann of the I Caucasian Army Corps, the offensive involved approximately 51,700 to 71,700 Russian troops, including infantry, cavalry, and , supported by 256 field guns, advancing from bases near into northeastern to secure key border positions such as Doğubeyazıt and Köprüköy. The operation marked Russia's preemptive strike across the frontier, ahead of broader Ottoman mobilization, and aimed to exploit the Ottoman Third Army's vulnerabilities amid the early chaos of the war. Initial Russian advances proved successful, with forces capturing the strategic town of Köprüköy by 7 after overcoming Ottoman defenses in the , including heavy fighting in the Eleşkirt Valley that resulted in significant Ottoman casualties and prisoners. However, the offensive faltered due to logistical challenges, harsh winter conditions, and the diversion of up to 40,000 Russian troops to the European fronts following defeats like Tannenberg, leaving Bergmann's command understrength against the Ottoman Third Army's roughly 150,000 men under Hasan İzzet Pasha. An Ottoman counterattack launched on 11 forced the Russians into a retreat, with fighting subsiding by 21 after reinforcements under General Przevalski stabilized the line near the border. The offensive concluded inconclusively, with Russian losses estimated at around 6,000 (including deaths from exposure) and Ottoman casualties exceeding 11,000 killed, wounded, or captured, highlighting the grueling terrain and weather of the Caucasian theater that would define the entire campaign. Despite its failure to achieve lasting gains, the Bergmann Offensive boosted Ottoman morale, encouraged Enver Pasha's subsequent ill-fated Sarikamish Offensive in December 1914, and underscored the strategic importance of the Caucasus front in diverting resources from both empires' primary European commitments.

Background

Strategic Context of the Caucasus Campaign

The Ottoman Empire's entry into World War I against Russia was precipitated by the Black Sea Raid on October 29, 1914, when Ottoman naval forces, under German influence, bombarded Russian Black Sea ports including Odessa, Sevastopol, and Novorossiysk, effectively initiating hostilities. This action prompted Russia to declare war on the Ottoman Empire on November 2, 1914, drawing the Caucasus region into the broader conflict as a secondary theater for both powers. The raid aligned with the Ottoman-German alliance signed on August 2, 1914, and served Ottoman strategic aims to secure influence in the Black Sea while provoking Russian engagement on multiple fronts. Russia's strategic priorities at the outset of the war centered on the European fronts against Germany and Austria-Hungary, viewing the Caucasus as a defensive periphery requiring minimal resources to safeguard against Ottoman incursions. To this end, Russian planners mobilized the Caucasus Military District by late July 1914 but prioritized redeploying experienced corps, such as the 1st and 4th Caucasian, to the main theaters, replacing them with less seasoned units like the 2nd Turkestan Corps. This approach reflected broader Tsarist objectives, including post-war ambitions for Black Sea access via the Straits and control of Constantinople, but initially limited offensive ambitions in the south to containment rather than expansion. The Caucasus theater presented formidable natural obstacles that amplified logistical strains for both sides, characterized by towering mountain ranges exceeding 3,000 meters, deep river valleys like those of the Euphrates, Aras, and Çoruh, and vast, rugged plains in northeast Anatolia. Harsh weather compounded these challenges, with early snowfalls from September onward accumulating to 1.5 meters, temperatures plunging below -30°C, and blizzards reducing visibility to mere meters, fostering widespread frostbite and hindering supply lines across poorly developed infrastructure spanning over 1,250 kilometers. In contrast to Russia's initially defensive stance, Ottoman leadership under War Minister Enver Pasha envisioned an aggressive push into Russian Transcaucasia to reclaim lost territories and ignite pan-Turkic uprisings among Muslim populations, deploying the Third Army for a major offensive supported by irregular forces from the Teşkilat-ı Mahsusa. This ambitious plan, rooted in pre-war pan-Islamic and pan-Turkic ideologies, aimed to extend Ottoman influence toward Turkestan but overlooked the region's environmental rigors, setting the stage for Russian forces under General Georgy Bergmann, commander of the I Caucasian Army Corps, to shift from defense to a preemptive offensive on 1 November 1914.

Russian Initiative and Planning

Following the Ottoman Black Sea Raid on 29–30 October 1914, which targeted Russian ports and precipitated Russia's formal declaration of war on 2 November, General Georgy Bergmann, commander of the I Caucasian Army Corps, initiated a preemptive strike by ordering his forces to cross the Ottoman border on 1 November. This decision reflected Russia's intent to seize the initiative in the Caucasus sector amid the broader entry of the into World War I. Russian intelligence assessments highlighted Ottoman vulnerabilities, estimating that the Third Army required a minimum of 40 days to concentrate troops effectively due to logistical and mobilization constraints in the region. These evaluations, informed by pre-war of Ottoman activities through consuls and emissaries, suggested a temporary weakness that Bergmann sought to exploit before full Ottoman reinforcements could arrive. The primary objectives were to capture Doğubeyazıt, thereby securing the southern flank against potential Ottoman incursions from Persia, and to advance toward Köprüköy to disrupt enemy lines of communication and fortifications along the frontier. These aims aligned with the broader strategic goal of protecting the Caucasus Military District while tying down Ottoman forces. Logistical preparations were anchored at the fortified base in Kars, with supply lines drawn from the Caucasus rail network and regional depots to sustain operations in the rugged terrain. By late October, Bergmann's corps mustered 51,700–71,700 men, including 100 battalions and 117 sotnias of cavalry, supported by 256 field guns and four Armenian volunteer druzhinas numbering in the hundreds to a thousand each. Reinforcement plans called for the integration of the 2nd Turkestan Corps, dispatched in August, to provide additional infantry and artillery for sustained pressure on Ottoman positions.

Opposing Forces

Russian I Caucasian Army Corps

The Russian I Caucasian Army Corps was commanded by General Georgy Bergmann, who directed approximately 51,700–71,700 men organized into four infantry divisions supported by artillery units during the early stages of the Caucasus Campaign. This included 100 battalions, 117 sotnias, and 256 field guns, with support from four combat and one reserve Armenian volunteer druzhinas. Bergmann, drawing on his prior service in the region, emphasized rapid advances through mountainous terrain to exploit Ottoman vulnerabilities, though his planning role remained subordinate to the overall Caucasus Army command under General Nikolai Yudenich. The corps' key units comprised the 20th, 21st, 25th, and 26th Infantry Divisions, each consisting of two brigades with multiple regiments equipped for combined arms operations, alongside Cossack cavalry detachments for reconnaissance and flanking maneuvers. These divisions formed the core striking force, with the infantry divisions providing the bulk of maneuver elements and the Cossacks adding mobility in the rugged landscape. Equipment included standard-issue Mosin-Nagant rifles for infantrymen, for suppressive fire, and field artillery such as 76 mm Model 1902 guns, supplemented by lighter mountain artillery pieces to navigate the Caucasus' steep valleys and passes. This armament was well-suited for the theater's demands, enabling sustained fire support despite logistical challenges posed by the terrain. The corps' composition incorporated local Armenian volunteers, organized into druzhinas (squads) that numbered several thousand and enhanced operational effectiveness through their familiarity with the local geography. Morale was generally high, reinforced by these volunteers' enthusiasm and the troops' prior experience in pre-war border skirmishes along the Russo-Ottoman frontier, which had honed skills in irregular warfare and high-altitude operations.

Ottoman III Army Composition

The Ottoman Third Army was commanded by Lieutenant General Hasan İzzet Pasha from November to December 1914, during which it opposed the Russian advance in the initial phases of the Caucasus Campaign. The army was structured around three main corps—the IX, X, and XI Corps—with an estimated total strength of 75,000 to 95,000 men assigned to the theater, though effective frontline forces were lower due to logistical constraints and the dispersed nature of deployments along the rugged frontier. The XI Corps, bearing the brunt of the initial Russian pressure, was positioned forward at Hasankale, while elements of the IX Corps held key positions at Köprüköy; additional units, including the 17th and 28th Infantry Divisions from the IX Corps, were stationed near Bayazit to guard southern approaches. The Ottoman forces faced significant equipment shortcomings that hampered their readiness for mountain warfare. Many troops were equipped with outdated Mauser and Gras rifles, with shortages in ammunition and modern small arms leaving some units underarmed; artillery support was limited to obsolete Krupp field guns from the late 19th century, numbering around 60 pieces for the XI Corps alone, insufficient for sustained defensive actions. Transport in the Caucasus terrain proved particularly challenging, as the army lacked adequate pack animals and vehicles suited for high altitudes, relying instead on overburdened local mules and human porters, which slowed resupply and mobility. In adopting a defensive posture, the Third Army fortified critical passes and river lines, such as those at Köprüköy, with entrenched positions and improvised barriers to channel enemy advances into kill zones. Scouting and flank security depended heavily on tribal irregulars from Kurdish and local militias, who provided intelligence on Russian movements but often proved unreliable in coordinated operations. This setup reflected Hasan İzzet's preference for a cautious defense over 's ambitious plans for a wider offensive into Russian territory.

Course of the Offensive

Initial Russian Advance

The Bergmann Offensive commenced on November 2, 1914, when elements of the Russian I Caucasian Army Corps, numbering approximately 51,700 to 71,700 men with supporting artillery, crossed the Ottoman border in the southern sector near the Aras River, initiating the first major engagement of the Caucasus Campaign. This advance marked Russia's preemptive strike ahead of the formal declaration of war, aiming to secure key positions and disrupt Ottoman defenses along the frontier. In the southern detachment under General Przhevalsky, Russian troops forded the Aras River and pushed toward Doğubeyazıt (Bayazit), capturing the strategically vital town and surrounding outposts, including Azap, following initial skirmishes with scattered Ottoman border guards and irregulars. These early clashes involved light resistance, allowing the Russians to overrun forward positions and establish a foothold in the region by mid-November. To exploit the element of surprise and outmaneuver Ottoman reinforcements, Russian commanders employed flanking tactics, directing infantry and cavalry units through rugged mountain passes to envelop enemy outposts and accelerate the advance beyond the river valley. This approach leveraged the corps' mobility in the initial phase, though it exposed supply lines to the difficult terrain of the Armenian highlands. Logistical difficulties soon emerged due to the severe November weather, as early snowfalls and subzero temperatures in the high altitudes hampered infantry progress, strained equipment, and complicated the movement of artillery and provisions across the frozen passes. Despite these setbacks, the initial gains positioned Russian forces for deeper penetration into Ottoman territory.

Battles at Köprüköy and Surroundings

The Russian I Caucasian Corps, under General Georgy Bergmann, launched its main assaults on Ottoman positions at Köprüköy between November 7 and 10, 1914, following an initial unopposed advance into Ottoman territory. These attacks involved coordinated infantry charges supported by artillery barrages, targeting the Ottoman Third Army's defensive lines along the Aras River valley near the town. The Russians sought to outflank the Ottoman positions by maneuvering through surrounding villages and elevated terrain, but encountered stiff resistance that turned the engagements into prolonged close-quarters fighting. Key combat unfolded in the vicinity of Köprüköy, where Ottoman forces under Hasan Izzet Pasha had established prepared defenses utilizing the natural barriers of the rugged Caucasus landscape. Russian infantry pressed forward with bayonet charges and hand-to-hand combat in narrow passes and village outskirts, but Ottoman artillery effectively disrupted these advances, as demonstrated by individual acts such as that of Corporal Ali Rıza Eti, who fired multiple rounds from a mountain gun to target Russian officers and halt an assault. The Ottomans supplemented their regular troops with local tribal auxiliaries familiar with the local terrain, enabling them to delay Russian progress through ambushes and rapid repositioning. The battles devolved into a stalemate by mid-November, as the Russians proved unable to achieve a decisive breakthrough despite their numerical superiority in the sector. Harsh weather conditions, including cold rains and muddy roads, compounded supply difficulties for the advancing Russians, while the steep heights and narrow valleys around Köprüköy favored the defenders and limited maneuverability. This tactical impasse highlighted the challenges of offensive operations in the mountainous frontier, forcing Bergmann's forces to consolidate rather than press further.

Ottoman Counteractions and Russian Retreat

Following the intense fighting at Köprüköy, the Ottoman Third Army under Commander Hasan Izzet Pasha adopted a deliberate strategy of ordered withdrawal, enticing the Russian forces deeper into Ottoman territory to overextend their supply lines while preserving Ottoman strength for a subsequent counteroffensive. This approach allowed the Ottomans to avoid decisive engagements in unfavorable positions and regroup effectively. On November 11, 1914, the Ottomans launched a coordinated counterattack with approximately 150,000 troops from the Third Army, targeting the exposed flanks of the Russian I Caucasian Army Corps and threatening encirclement. The assault, involving four infantry divisions and a cavalry division along the Aras River, exploited the Russians' overstretched positions and logistical vulnerabilities, forcing General Georgy Bergmann's forces to abandon Köprüköy by November 12. Ottoman reinforcements, bolstering the Third Army's capabilities, arrived in the region and contributed to stabilizing the defensive lines by mid-November, preventing further Russian penetration. Under mounting Ottoman pressure and severe supply shortages, the Russian retreat commenced on November 16, 1914, as Bergmann's corps faced the risk of collapse. The arrival of Russian reinforcements under General Przevalsky temporarily checked the Ottoman momentum on November 16–17, but could not reverse the overall withdrawal. Sporadic skirmishes persisted as the Russians fell back, ultimately reestablishing positions near by late November 1914, marking the effective end of the .

Aftermath

Casualties and Material Losses

The Bergmann Offensive resulted in substantial casualties for the Russian I Caucasian Army Corps, with estimates placing total losses at approximately 6,000 to 7,000 killed, wounded, missing, or dead from exposure. Ottoman forces from the III Army incurred approximately 12,000 casualties during the engagement, including killed, wounded, captured, and deserters, primarily from the defensive stands and counteractions at Köprüköy and surrounding areas. Material losses for the Ottomans included captured prisoners and equipment during the Russian advance. In contrast, the Russians experienced some material setbacks during the disorganized withdrawal, though specific captures of artillery by Ottomans are not well-documented. High Russian attrition was exacerbated by exposure to severe cold weather in the mountainous terrain, outbreaks of disease among troops, and the unrelenting intensity of close-quarters combat. These casualty levels aligned with broader norms in the Caucasus Campaign, where environmental hardships frequently compounded combat-related injuries and non-combat losses across both sides.

Strategic and Operational Impact

The Bergmann Offensive, launched by under General Georgy Bergmann in early November 1914, ultimately failed to achieve a deep penetration into Ottoman territory, stalling after an initial advance capturing Köprüköy, approximately 50 km into Ottoman territory. While the Russians secured some border areas and disrupted Ottoman defensive preparations around Köprüköy, the operation exposed significant logistical vulnerabilities, including supply shortages and difficulties in coordinating infantry and artillery across rugged terrain, leading to a retreat by mid-November. This short-term outcome tied down Ottoman resources on the eastern front, preventing immediate redeployments elsewhere, but prevented the Russians from threatening key positions like Erzurum. The offensive's lessons profoundly influenced subsequent Russian command under General Nikolai Yudenich, who assumed leadership of the Caucasus Army in early 1915 and emphasized improved logistics, defensive consolidation, and surprise maneuvers to mitigate the vulnerabilities revealed at Köprüköy and Azap. Yudenich's adaptations, informed by Bergmann's setbacks in winter operations and supply lines, enabled more effective campaigns later, such as the 1916 Erzurum offensive. For the Ottomans, the successful repulsion of the Russian thrust—despite heavy casualties at engagements like Azap—provided a temporary morale boost to the Third Army, encouraging Enver Pasha to launch the ambitious Sarıkamış Offensive in December 1914 to capitalize on the perceived weakness of Russian forces. In the long term, the offensive exacerbated ethnic tensions in the Caucasus by highlighting the role of Armenian volunteers, who provided intelligence and auxiliary support to Russian units during the advance, contributing to Ottoman suspicions and reprisals. This dynamic set the stage for the 1915 Armenian deportations and massacres, as Ottoman authorities viewed Armenian communities as a security threat amid the Russian incursions, resulting in widespread displacement and violence that reshaped regional demographics and alliances. The operation's estimated 7,000 Russian casualties underscored the high cost of frontier warfare, further straining both sides' resources in the broader Caucasus Campaign.
