Major Japanese advances during the first six months of the War with Japan

In December 1941, Japan launched a coordinated series of suprise attacks in the Central Pacific and in eastern and southeastern Asia. For the next five months, the Japanese military was successful beyond their expectations in portions of the central, south, and southwestern Pacific and in southeast Asia, the Philippines, and the Dutch Indies.

Japanese Empire - Mid 1942

The First American Carrier Raids

When the Japanese attacked Pearl Harbor in December 1941, the American aircraft carriers based at Pearl were at sea, and thus survived. In Februrary and March of 1942, US carrier and cruiser forces made a series of attacks on Japanese positions in the central and southwest Pacific. Although these air raids and shore bombardments failed to inflict major damage, they did not incur major losses and served as valuable training exercises.

1 Feb '42 - Marshall & Gilbert Islands, USS Enterprise & USS Yorktown
20 Feb '42 - off Rabaul
24 Feb & 4 Mar '42 - Wake & Marcus Islands
10 Mar '42 - Lae & Salamaua, New Guinea - USS Lexington & USS Yorktown

Preserving the Australian Lifeline

In early 1942 it became apparent that neither the Philippines or the Dutch Indies could be held. Thus attention turned to the protection of the giant island nation of Australia, most of whose combat troops were away fighting with England against German and Italian forces.

The sea links to Australia from the west coast of the United States and from the Panama Canal were in jeopardy. Thus, as the first ground troops were dispatched from the United States west across the Pacific, priority was given to protecting these sea links.

Triangles denote bases developed to provide support and security for shipping.
Until the later part of 1944, Brisbane, Australia and the French colony of New Caledonia were major rear-area American bases.

The arrows denote the WWII sea route from Hawaii to Australia.
