The 1st Marine Division's landing at Cape Gloucester on 26 December 1943 was successful. The Marines secured the airfields that were the main objective of the operation on 29 December against only light Japanese opposition. Heavy fighting took place during the first two weeks of 1944 when the Marines advanced south to the east of their initial beachhead to secure Borgen Bay. Little fighting took place once this area had been captured and the Marines patrolled extensively in an attempt to locate the Japanese. On 16 February, a Marine patrol from Cape Gloucester made contact with an Army patrol from Arawe at the village of Gilnit. On 23 February, the remnants of the Japanese force at Cape Gloucester were ordered to withdraw to Rabaul.
