The Slamat disaster is a succession of three related shipwrecks during the Battle of Greece on 27 April 1941. The Dutch troopship Slamat and the Royal Navy destroyers HMS Diamond and HMS Wryneck sank as a result of air attacks by Luftwaffe Junkers Ju 87 dive bombers. The three ships sank off the east coast of the Peloponnese during Operation Demon, which was the evacuation of British, Australian and New Zealand troops from Greece after their defeat by invading German and Italian forces. The loss of the three ships caused an estimated 983 deaths. Only 66 men survived.
