U.S. TROOPS ARRIVING IN AUSTRALIA. In March the headquarters of the Allied forces in the Southwest Pacific was established at Melbourne. The Netherlands East Indies had fallen to the enemy and it was necessary to build up a force in the Southwest Pacific area to combat the Japanese threat to Australia. With the Japanese blocking the sea lanes of the Central Pacific, a new line of supply to the Far East was established by way of the Fiji Islands, New Caledonia, and Australia.

COAST ARTILLERY TROOPS entraining at Melbourne, March 1942. The Japanese air attack on Darwin in February proved that the north coast of Australia was too open to attack by enemy planes and thereafter the Allies concentrated their forces along the eastern coast from Melbourne to Townsville.

AIRCRAFT CARRIER USS LEXINGTON burning after the Battle of the Coral Sea. The Japanese planned to strengthen their bases in the Southwest Pacific and to sever the line of communications between the United States and Australia. One enemy task force, sent to take Tulagi in the southern Solomons, was attacked at sea and lost a number of ships, but nevertheless landed troops and captured Tulagi. Another task force intended for Port Moresby did not reach its objective because of an attack by U.S. naval forces. This battle, called the Battle of the Coral Sea, was fought on 7-8 May 1942 and was the first carrier against carrier battle in history.
