- The Royal Navy seaplane carrier Ben-my-Chree is sunk by Ottoman artillery while in harbour at Kastellorizo Island in Greece. Ben-my-Chree is the only aviation ship of any nationality to be sunk by enemy action during World War I.
- The last Allied troops left Cape Helles, bringing the Gallipoli campaign to an end. In just over a week, 35,000 soldiers, 3,689 horses and mules, 127 guns, 328 vehicles, and 1,600 tons of stores had been evacuated. Approximately 508 horses and mules were slaughtered or left behind. The evacuation is the only real Allied success; during the 259 days of the campaign, they had sustained more than 252,000 casualties, 26,000 of which were Australian. Turkish casualties numbered about 251,000. Allied military command was greatly discredited by the failure of the Gallipoli campaign.
