On 13 May, Khmer Rouge forces seized the American-owned container ship, SS "Mayaguez", off Koh Tang Island, Cambodia. Both "Vega" and "Harold E. Holt" made full speed ahead for the area, while American forces soon mobilized to gain the release of the ship and its crew from the hands of the Cambodians. Arriving on the 15th, "Vega" stood by to provide services while "Harold E. Holt" moved in and delivered a detachment of the 1st Battalion 4th Marines]], who boarded the container ship. While the incident was brought to a conclusion by the swift recapture of the ship and her crew, the routine task of conducting underway replenishments to ships of the 7th Fleet in southeast Asian waters continued unabated in the wake of the fall of Vietnam and Cambodia.
