Cause

Britain sought to force open the Dardanelles straits to knock the Ottoman Empire out of the war. After a failed naval assault in March 1915, an amphibious operation was planned to seize the Gallipoli peninsula, with Cape Helles selected as the primary landing zone for the 29th Division to advance inland and capture the forts guarding the straits.

Event

On 25 April 1915, British forces landed across multiple beaches at Cape Helles under Royal Navy gunfire support, accompanied by diversionary landings at Bulair, Kum Kale, and Besika Bay. Despite meagre Ottoman defences, V and W beaches turned into bloodbaths due to mismanagement by Hunter-Weston, while opportunities at less-contested beaches were not exploited. The British established a narrow foothold but failed to reach their first-day objectives.

Consequence

For two months following the initial landing, British forces fought expensive battles to achieve the objectives set for the first day, including the capture of Achi Baba. They were ultimately repulsed by Ottoman defenders, leaving the campaign mired in stalemate. The failure contributed to the eventual Allied withdrawal from Gallipoli and the broader collapse of the Dardanelles strategy.
