The Battle of Sari Bair is also known as the August Offensive. This battle was the last attempt, fail attempt, by the Britain, to take over control over the Gallipoli peninsula in the World War I. The Ottoman Empire had control over the Gallipoli peninsula. Since the invasion (25 April 1915), the Gallipoli Campaign had two fronts. They were: Helles and Anzac. The Allies wanted to carry the offensive to the Helles battlefield. This plan was responsible for many casualties, but there were little gain. The British command made a new plan in August 1915. They wanted to capture the Sari Bair ridge. This was the high ground, above the Anzac landing. It also was in the middle of the peninsula.
The operation began with a landing north of Anzac. The exact spot was 8 kilometers from the Anzac at Suvla Bay. It was made in conjunction with the New Zealand and Australian forces. Together, they wanted to capture the high land and connect with the Suvla landing.
The battle was finished on 21 August. The front lines, at Anzac and Suvla stayed, as the reminder of this campaign. Fighting still lasted, but there were no major advances anymore.
General Hamilton planned to execute one more attack in order to link Anzac and Suvla. In order to achieve this, they had to gain control over the Hill 60, 'W' Hills from Suvla and Scimitar Hill. The attack should start on 21 August. De Lisle had 2nd Mounted Division and 29th Division, as they were moved, as additional reinforcement, to Suvla. Britain, Australia and New Zealand lost 20.155 soldiers in this battle. The Ottoman Empire lost 12.000.
