When the former German Pacific Island colonies were divided among the victors after World War I, the Melanesia colonies were given to Australia to administer. Rabaul, on the northern tip of New Britain Island in the Bismarck Island chain, was the capital of this mandate. Rabaul had a magnificent harbor, with sheltered access from the north and to the south. Early in 1942, Japanese forces overwhelmed the Australian battalion defending Rabaul. The Japanese soon developed Rabaul into the main Japanese base in the South/Southwest Pacific.

For nearly a year, from June 1943 to March of 1944, American, Australian and New Zealand military actions in the South and Southwest Pacific surrounded Rabaul with air and naval bases. This, combined with bombing raids on Rabaul, made an amphibious attack on Rabaul unnecessary.
These actions neutralizing Rabaul, in the Solomons, on eastern New Guinea, and on southern New Britain and the Admiralty Islands, were collectively called Operation Cartwheel. Below I list the major Operation Cartwheel amphibious landings in the Bismarck and Admiralty Islands.

Arawe, New Britain, 15 Dec 1943 - 24 Feb 1944

Before the larger Cape Gloucester landing in western New Britain, the 112th Cavalry Regiment landed at Arawe to the southeast in a diversionary attack. As the accompanying map shows, Troop A's landing was repelled by Japanese machine gun fire that sank twelve of their fifteen rubber boats. The destroyer Shaw suppressed the enemy fire and Troop A survivors were rescued by the SC-699, a small submarine chaser.
Incidently, just over two two years earlier the Shaw had exploded at Pearl Harbor during the Japanese attack. 118 men died in the 112th Cavalry Regiment's baptism of fire. |

Cape Gloucester, New Britain, 26 Dec 1943 - 15 Jan 1944
|
Eleven days after the Arawe landing, the 1st Marine Division landed at Cape Gloucester. Here they met more determined resistance, and had to fight tropical storms as well as Japanese.
310 Americans died at Cape Gloucester. |

The Admiralty Islands, 24 Feb 1944 -
|
Inaccurate intelligence suggested that the Japanese had abandoned the Admiralty Islands. When the 1st Cavalry Division invaded, they encountered moderate Japanese resistance.
The Admiralties cost 326 American dead. However, Seeadler Harbor and Momote airfield became important American bases. |
