The
Gallipoli Campaign, also known as the
Dardanelles Campaign, the
Battle of Gallipoli or the
Battle of Çanakkale , was a campaign of
World War I that took place on the
Gallipoli peninsula (
Gelibolu in modern Turkey) in the
Ottoman Empire between 25 April 1915 and 9 January 1916. The peninsula forms the northern bank of the
Dardanelles, a
strait that provided a sea route to the
Russian Empire, one of the
Allied powers during the war. Intending to secure it, Russia's allies Britain and France launched a naval attack followed by an amphibious landing on the peninsula, with the aim of capturing the Ottoman capital of
Constantinople (modern
Istanbul). The naval attack was repelled and after eight months' fighting, with many casualties on both sides, the land campaign was abandoned and the invasion force was withdrawn to
Egypt.
