The captain, concerned about the warnings of war, left the island without refueling. The smaller tug had to refuel and remained to do so. "Arthur Foss" was about twelve hours into the voyage to Honolulu when word of the attack on Pearl Harbor was received. The tug's crew repainted the tug with what paint was available and kept radio silence. The tug, overdue and thought lost, was spotted by Navy patrol planes and made Pearl Harbor on 28 December with fuel for less than a day's operation left. The crew of "Justine Foss" were captured when the island was taken by the Japanese with all but one eventually executed. The Navy put "Arthur Foss" in service as a yard tug under the name "Dohasan" from early 1942 until February 1945. The tug was laid up until 1947 when it was returned to Foss and transported to its home area where it was rehabilitated for company service in 1948. It served the company for twenty more years until retirement in July 1968.
