In early May, the 2nd Brigade was selected to move to Cape Helles to reinforce the British forces for the Second Battle of Krithia. After being transferred by boat, on 8 May, Bennett advanced with his battalion in impossible conditions. Bennett was the only officer of the 6th, and one of few in the 2nd Brigade, to survive the advance unscathed, although he was lucky do so; as he led the charge, a Turkish bullet hit the ammunition pouch he wore, exploding the ammunition in it. He was knocked off his feet, but otherwise unharmed. With a handful of men, he achieved the furthest advance of the attack. He became commander of the 6th Battalion the next day. The battalion was then returned to Anzac by a trawler, and shortly afterwards, Bennett's command of the battalion was confirmed and he was promoted to lieutenant colonel.
