Australian Naval History on 26 August 1967

Four members of Clearance Diving Team 3 participated in an unsuccessful assault on strong enemy positions on the banks of a channel near Nui Truong Phi, Vietnam. The force was carried in five motorised junks escorted by patrol boats. As it neared the landing place it came under intense enemy fire. The divers blew up two US patrol boats previously captured by the Viet Cong, before the force was withdrawn. AB D. C. Trompp was wounded in the action and became the first RAN casualty in the Vietnam War.
