Sherlock, of the RAN Clearance Diving Team 3, carried out an underwater night search of the hull of MV HERADIA at Vung Tau, Vietnam, after the capture of a Viet Cong diver alongside the ship. Knowing that another enemy diver was in the vicinity, they continued their search until they found an explosive charge secured alongside the ship. After removal of the charge they re-entered the water and captured the enemy diver.
