The Battle of Lone Pine was fought between Australian and New Zealand Army Corps (ANZAC) and Ottoman Empire forces during the Gallipoli Campaign of the First World War, between 6 and 10 August 1915. The battle was part of a diversionary attack to draw Ottoman attention away from the main assaults being conducted by British, Indian and New Zealand troops around Sari Bair, Chunuk Bair and Hill 971, which became known as the August Offensive.

The Battle of Sari Bair, also known as the August Offensive, represented the final attempt made by the British in August 1915 to seize control of the Gallipoli peninsula from the Ottoman Empire during the First World War.
