Gallipoli Campaign in the context of "Battle of Sari Bair"

Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term amphibious first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.

Amphibious warfare includes operations defined by their type, purpose, scale and means of execution. In the British Empire at the time these were called combined operations which were defined as "...operations where naval, military or air forces in any combination are co-operating with each other, working independently under their respective commanders, but with a common strategic object." All armed forces that employ troops with special training and equipment for conducting landings from naval vessels to shore agree to this definition. Since the 20th century, an amphibious landing of troops on a beachhead is acknowledged as the most complex of all military maneuvers. The undertaking requires an intricate coordination of numerous military specialties, including air power, naval gunfire, naval transport, logistical planning, specialized equipment, land warfare, tactics, and extensive training in the nuances of this maneuver for all personnel involved.

ANZAC Cove (Turkish: Anzak Koyu) is a small cove on the Gallipoli peninsula in Turkey. It became famous as the site of World War I landing of the ANZACs (Australian and New Zealand Army Corps) on 25 April 1915. The cove is 600 metres (2,000 ft) long, bounded by the headlands of Arıburnu to the north and Little Arıburnu, known as Hell Spit, to the south. Following the landing at ANZAC Cove, the beach became the main base for the Australian and New Zealand troops for the eight months of the Gallipoli campaign.

Herbert Henry Asquith, 1st Earl of Oxford and Asquith (/ˈæskwɪθ/ ASS-kwith; 12 September 1852 – 15 February 1928), generally known as H. H. Asquith, was a British statesman and Liberal politician who was Prime Minister of the United Kingdom from 1908 to 1916. He was the last prime minister from the Liberal Party to command a majority government, and the most recent Liberal to have served as Leader of the Opposition. He played a major role in the design and passage of major liberal legislation and a reduction of the power of the House of Lords. In August 1914 Asquith took the United Kingdom of Great Britain and Ireland and the British Empire into the First World War. During 1915 his government was vigorously attacked for a shortage of munitions and the failure of the Gallipoli Campaign. He formed a coalition government with other parties, but failed to satisfy critics, was forced to resign in December 1916 and never regained power.

After attending Balliol College, Oxford, he became a successful barrister. In 1886 he was the Liberal candidate for East Fife, a seat he held for over thirty years. In 1892 he was appointed Home Secretary in William Ewart Gladstone's fourth ministry, remaining in the post until the Liberals lost the 1895 election. In the decade of opposition that followed, Asquith became a major figure in the party, and when the Liberals regained power under Sir Henry Campbell-Bannerman in 1905, Asquith was named Chancellor of the Exchequer. In 1908 Asquith succeeded him as prime minister. The Liberals were determined to advance their reform agenda. An impediment to this was the House of Lords, which rejected the People's Budget of 1909. Meanwhile, the South Africa Act 1909 passed. Asquith called an election for January 1910, and the Liberals won, though they were reduced to a minority government. After another general election in December 1910, he gained passage of the Parliament Act 1911, allowing a bill three times passed by the Commons in consecutive sessions to be enacted regardless of the Lords. Asquith was less successful in dealing with Irish Home Rule. Repeated crises led to gun running and violence, verging on civil war.

Stanley Melbourne Bruce, 1st Viscount Bruce of Melbourne (15 April 1883 – 25 August 1967) was an Australian politician, statesman and businessman who served as the eighth prime minister of Australia from 1923 to 1929. He held office as the leader of the Nationalist Party, having previously served as the treasurer of Australia from 1921 to 1923.

Born into a briefly wealthy Melbourne family, Bruce studied at the University of Cambridge and played a leading role in his family's softgoods firm following the suicide of his father John Munro Bruce. He served on the front lines of the Gallipoli Campaign in World War I and returned to Australia wounded in 1917, becoming a spokesman for government recruitment efforts. He gained the attention of the Nationalist Party and prime minister Billy Hughes, who encouraged a political career. He was elected to the House of Representatives in 1918, becoming member of parliament (MP) for the seat of Flinders. He was appointed as treasurer in 1921, before replacing Hughes as prime minister in 1923. He established an anti-socialist coalition government with the agrarian Country Party, working closely with Country leader Earle Page in an arrangement that pioneered the modern Liberal–National coalition.

Lieutenant-General Sir Frederick William Stopford, KCB, KCMG, KCVO (2 February 1854 – 4 May 1929) was a British Army officer, best remembered for commanding the landing at Suvla Bay in August 1915, during the Gallipoli Campaign, where he failed to order an aggressive exploitation of the initially successful landings.
