Indian Ocean raid
"Hermes" was berthed in Trincomalee on 8 April when a warning of an Indian Ocean raid by the Japanese fleet was received, and she sailed that day for the Maldives with no aircraft on board. On 9 April a Japanese scout plane spotted her near Batticaloa, and she was attacked by several dozen dive bombers shortly afterwards. With no air cover, the carrier was quickly sunk by the Japanese aircraft. Most of the survivors were rescued by a nearby hospital ship, although 307 men from "Hermes" were lost in the sinking.
