Alfred John Shout, VC, MC (8 August 1882 – 11 August 1915) was a New Zealand–born soldier and an Australian recipient of the Victoria Cross (VC), the highest decoration for gallantry "in the face of the enemy" awarded to members of the British and Commonwealth armed forces. Shout was posthumously awarded the VC for his actions at Lone Pine in August 1915, during the Gallipoli campaign of the First World War. After Ottoman forces had counterattacked and seized a large stretch of the Australians' front line, Shout gathered a small party of men and charged down one trench throwing bombs. He killed eight Turkish soldiers, and managed to clear others to retake the trench. In a similar action later that day, and supported by another officer, he recaptured further ground amid heavy fighting. In the final push forward, Shout simultaneously lit three bombs to lob at the enemy. He successfully threw two, but just as the third left his hand it detonated. Shout was severely wounded and died two days later.

Born in Wellington, Shout had served in the Second Boer War as a teenager. He rose to sergeant and was mentioned in despatches for saving a wounded man before being discharged in 1902. He remained in South Africa for the next five years, serving as an artilleryman in the Cape Colonial Forces from 1903. With his Australian-born wife and their daughter, Shout immigrated to Sydney in 1907. The family settled in Darlington, where Shout worked for Resch's Brewery as a carpenter and joiner. He was also active in the part-time Citizens' Forces, being commissioned just prior to the outbreak of the First World War. In August 1914, he joined in the Australian Imperial Force (AIF) for active service overseas and was appointed a lieutenant in the 1st Battalion. After training in Egypt, he took part in the Anzac landings at Gallipoli on 25 April 1915. For his leadership during the invasion and its immediate aftermath, Shout was awarded the Military Cross and later mentioned in despatches. Shout's three gallantry awards at Gallipoli made him the most highly decorated member of the AIF for the campaign.

Alfred John Shout was born in Wellington, New Zealand, on 8 August 1882. He was the eldest of nine children to an English-born father, John Richard Shout, and Irish mother, Agnes Mary (née Kelly, formerly McGovern). Information on Alfred Shout's early life is rather scant and the details differ between sources, but according to his First World War attestation form he was privately educated. In early 1900, Shout travelled to South Africa with his elder half-brother, William McGovern. The brothers sought to join one of the colonial contingents then engaged in the Second Boer War; Alfred enlisted in the newly raised Border Horse on 17 February 1900, while William (using the surname Shout) found a place in Bethune's Mounted Infantry. The Border Horse was an irregular colonial force formed in eastern Cape Colony, and Shout was allotted to the unit's No. 1 Company with the service number 9216.

Serving at Wittebergen, Transvaal, and in the Cape Colony with the Border Horse, Shout was twice wounded, including once in the chest. In an action at Thabaksberg on 29 January 1901, the then Lance Corporal Shout assisted in maintaining the position of his men. At one point during the engagement, he ventured out under heavy rifle fire to retrieve a wounded man, and brought him back to a covered position; Shout's bravery in this action earned him a mention in despatches. He was promoted to sergeant on 7 May 1901, and discharged from the Border Horse 16 days later. He then served with the Stellenbosch District Mounted Troop until 1902. Shout was issued the Queen's South Africa Medal with "Wittebergen", "Transvaal" and "Cape Colony" clasps, and the King's South Africa Medal with the clasps "South Africa 1901" and "South Africa 1902" for his service in the Boer War.

Shout decided to remain in South Africa after his discharge and, in 1903, enlisted in the Cape Colonial Forces. He was made a sergeant in Prince Alfred's Own Cape Field Artillery, with which he served until 1907. While living in Cape Town, Shout married Rose Alice Howe, an Australian from Sydney, in 1905; the couple had a daughter named Florence in June that year. In 1907, the Shout family immigrated to Australia, settling in the Sydney suburb of Darlington. Here, Shout gained employment as a carpenter and joiner at Resch's Brewery. He also joined the 29th Infantry Regiment of the part-time Citizens' Forces shortly after arriving in Sydney, was a foundation member of the 29th Infantry Club, and a regular visitor at the Randwick rifle range, where he gained a reputation as an excellent shot. Shout was commissioned as a second lieutenant in the Citizens' Forces on 16 June 1914.

Following the outbreak of the First World War, Shout applied for a commission in the newly raised Australian Imperial Force (AIF) on 18 August 1914. The AIF was formed as Australia's expeditionary force to fight in the war, as the Citizens' Forces were restricted to home defence per the Defence Act (1903). Shout's application was accepted on 28 August and he was posted to the 1st Battalion as a second lieutenant in F Company, commanded by Lieutenant Cecil Sasse. According to his medical assessment at the time, Shout stood at 5 feet 11 inches (1.80 m), weighed 12 stone (170 lb; 76 kg), and was recorded as having "good" eyesight. On 18 October, the 1st Battalion embarked for the Middle East, with Shout boarding HMAT Afric at Sydney. Sailing via Albany, Western Australia, the troopship arrived in Egypt on 2 December. Shortly after, the 1st Battalion was reorganised into four companies; Shout was allotted to D Company as a platoon commander. The battalion spent the next four months training in the Egyptian desert, during which time Shout was promoted lieutenant on 1 February 1915.

As part of an endeavour to defeat the Ottoman Empire and force a supply route through to Russia via the Bosporus and the Black Sea, the British War Council formulated a plan to invade the Gallipoli Peninsula. On 25 April 1915, the men of the 1st Australian Brigade—of which the 1st Battalion was part—landed at Anzac Cove between 05:30 and 07:30 among the second and third waves of Australian troops. The 1st Battalion was meant to be held in reserve, but due to heavy casualties and confusion the unit soon went into action. Following a request for reinforcements, Shout moved up with one of the 1st Battalion's companies to the hill feature Baby 700. Arriving at the position around 11:00, he led a party to hold the rear left flank of the hill as part of the Australians' rearguard action. The Australian position on Baby 700 had become dire by that afternoon, a situation compounded by the small number of available infantry in the area and the complete lack of artillery support, when the Turkish forces launched a counter-assault. By this time, Shout and Lieutenant Leslie Morshead of the 2nd Battalion were the only two surviving officers in their sector of the line. At 16:30, the Turks broke through the defensive line and the Australians were forced to abandon their position on the hill. Shout was one of the last to evacuate, and withdrew down towards the beach. During his retreat, Shout encountered Lieutenant Colonel George Braund, commanding officer of the 2nd Battalion, on Walker's Ridge. Braund dispatched Shout to the beach with a request for reinforcements. Shout duly relayed the message, and was immediately tasked with leading 200 stray men to reinforce the thin defensive line near Braund's position. Shout established a post at the base of the ridge as dusk began to fall, and his men started to dig in.

... Lieutenant Shout was a hero. Wounded himself several times, he kept picking up wounded men and carrying them out of the firing line. I saw him carry fully a dozen men away. Then another bullet struck him in the arm, and it fell useless by his side. Still he would not go to the rear. "I am here with you boys to the finish", was the only reply he would make ... A little later Lieutenant Shout was wounded again, and fell down. It was cruel to see him. He struggled and struggled until he got to his feet, refusing all entreaties to go to the rear. Then he staggered and fell and tried to rise again. At last some men seized him and carried him away, still protesting.
