Gallipoli 1915

The Gallipoli Campaign, also known as the Dardanelles Campaign,
the Battle of Gallipoli was a campaign of WW1
that took place on the Gallipoli peninsula (Gelibolu in modern Turkey) in
the Ottoman Empire between 17 Feb.1915- 9 Jan.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was abandoned and the invasion force was withdrawn to Egypt.
