The following map shows the South Pacific area sometimes known as Melanesia.  This area was under Australian administration before the Japanese invasions of early 1942. Cape York, on the bottom left, is part of Australia itself.​

• Between January and July of 1942, Japanese forces occupied key locations in Melanesia.
• From the beginning of the Solomon Islands campaign on Guadualcanal in August 1942, and until the Gilbert Islands campaign to the east in November 1943, most Allied combat in the Pacific was in the area shown above.
• United States, Australian, and New Zealand forces painfully forced the Japanese from the occupied areas in brutal battles sometimes lasting for months. Over twenty Pottawattamie County area servicemen, Army, Air Force, Navy and Marine, died.
