Troops land at Anzac Cove in the Dardanelles during the battle between Allied forces and Turkish forces at the Gallipoli Peninsula for access to the strategic Sea of Mamora and eventually to Constantinople (Istanbul). In February 1915 Turkish mines sank 6 British battleships, causing the naval assault on the Dardanelles to stall. A second Allied landing at Gallipoli failed in August and British forces evacuated Gallipoli in November 1915.
