The Bombing of Darwin, also known as the Battle of Darwin, on 19 February 1942 was the largest single attack ever mounted by a foreign power on Australia. On that day, 242 Japanese aircraft, in two separate raids, attacked the town, ships in Darwin Harbour and the town's two airfields in an attempt to prevent the Allies from using them as bases to contest the invasion of Timor and Java during World War II.
