The August Offensive
With the opposing forces deadlocked, a new offensive was launched in early August. The plan called for allied troops to capture the Sari Bair range north of Anzac, while the British made another effort to break out at Helles. Simultaneously, British troops would land further north at Suvla Bay. It was an overly ambitious plan, but something had to be done to break the stalemate.
On 6 August the Australians launched a diversionary attack at Lone Pine. The main Turkish trenches were captured, but bitter hand-to-hand fighting lasted four days. This terrible battle cost 2,277 Australian casualties. An attack at The Nek early next morning was intended to coincide with the capture of Chunuk Bair. Four waves of Australian light horsemen were ordered to rush this narrow strip of ground. But plans went awry and coordination was lost. They were mown down by machine-gun fire in a futile affair: of the 600 men who went forward, almost 400 became casualties.
The offensive had failed, and the stalemate resumed. The campaign on Gallipoli was eventually abandoned, and the troops withdrawn from the peninsula in December 1915.
