On the morning of 19 February 1942, 188 aircraft launched from four Japanese carriers in the Timor Sea and turned south toward Darwin. By day's end, 236 people were dead, nine ships lay on the harbor floor, and Australians understood something that distance had long allowed them to deny: the war had reached home. The Axis naval campaign against Australia would stretch from 1940 to 1945, encompassing German surface raiders laying mines off Sydney, Japanese midget submarines penetrating Sydney Harbour, aerial bombardments of northern towns, and a lone German U-boat prowling the southern coast on Christmas Eve 1944. About 40 Allied merchant ships were damaged or sunk in Australian waters, and the campaign forced Australia to devote substantial military resources to defending a coastline most had assumed was too remote to threaten.
