A British-Australian commando operation, Mission 204, was initialized in February 1942 to provide training to Chinese guerilla troops. The mission conducted two operations, mostly in the provinces of Yunnan and Jiangxi. The first phase achieved very little but a second more successful phase was conducted before the withdrawal.
The following month, Szlama Ber Winer escaped from the Chełmno concentration camp in Poland and passed information about it to the Oneg Shabbat group in the Warsaw Ghetto. His report, known by his pseudonym as the Grojanowski Report, had reached London by June 1942.
The Bombing 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's harbor.
