By January 1945, as the war progressed steadily towards the Japanese homeland, "Trinity" continued her unglamourous but vital job of plying the triangular New Guinea-Shouten Islands-Admiralty Islands route, shuttling cargoes of oil needed to keep the warships of the Fleet in operation. Arriving at Leyte, Philippines, in May 1945, she returned to waters from which she had been driven so unceremoniously in those dark days of December 1941. For the remainder of her active service, she operated in the western Pacific through the end of the war and the early months of the occupation.
