<human>:  When did the bombing of Darwin, Australia during World War II occur?
<bot>: The bombing of Darwin took place on February 19th, 1942. It was a surprise attack on the city by the Japanese. The Japanese had occupied the Northern Territory of Australia for a few years, but this attack was the first time they attacked an Australian city. The Japanese had been planning to attack Darwin for a long time, but they needed a good reason to justify the attack. The bombing of Darwin was the perfect reason!
