"Ark Royal"s aircraft provided support to the Australian and New Zealand troops at Anzac Cove as they landed on 25 April on the Gallipoli Peninsula. Two days later, the ship was taken under fire by the Ottoman predreadnought , firing across the peninsula, and she had to move in a hurry to avoid being hit. A month later, the battle on the peninsula had bogged down and the success of the German submarine in sinking two British predreadnoughts forced "Ark Royal" to move to a safer anchorage at Imbros at the end of May. There she became a depot ship for all the seaplanes in the area, while her own aircraft continued to support operations at Gallipoli. On occasion, aircraft were loaned out to other ships for reconnaissance or observation missions.
