While in transit, as a result of overcrowding in training camps in the United Kingdom, the 1st Division was diverted to Egypt with the intention that it would complete its training there before moving to the Western Front at a later date. The decision by the Allies to force a passage through the Dardanelles interrupted this process, as the 1st Division was allocated to take part in the Gallipoli Campaign. During the landing at Anzac Cove on 25 April 1915, Bennett fought on the southern flank of the Anzac beachhead. He led 300 men of his battalion to an advanced position on Pine Ridge, south of Lone Pine. While directing the defence of this position, Bennett was wounded in the shoulder and wrist and forced to retire to the beach for treatment. When the Turkish forces counter-attacked in the evening, the 6th Battalion force on Pine Ridge was isolated and killed to the last man, including Bennett's younger brother, Godfrey. Instead of accepting evacuation on a hospital ship, after having his wounds treated, Bennett returned to his battalion.
