Between The Battle of the Philippine Sea, June 19th and 20th 1944, and The Battle of Leyte Gulf, October 23rd to 26th 1944, the Japanese attempted to reinforce their forces occupying the Philippines. For divers, Coron's history started on 24 September 1944 when a US Navy strike force of fighters and dive bombers attacked a Japanese supply fleet of up to 24 ships, at anchor, in Coron Bay and around Busuanga Island.
