Early on the morning of 25 April 1915, Allied forces landed on the Gallipoli peninsula in Ottoman Türkiye. The British Army landed at Cape Helles. Troops of the Australian and New Zealand Army Corps (ANZAC) landed north of Gaba Tepe (Kabatepe) headland, on a beach later called ‘Anzac Cove’. French troops landed in a feint at Kum Kale on the Dardanelles Asian shore before moving to the Helles sector on Gallipoli.

Ferocious Turkish resistance resulted in protracted trench warfare through the forbidding scrubby slopes and ravines. Fighting in the landings and early battles resulted in heavy casualties on both sides.

The unhygienic conditions for soldiers on Gallipoli caused serious illnesses. As the campaign moved into summer, more men were evacuated because of illness than wounds sustained during the conflict.
