Royal Navy Hong Kong 1951-54

My fatherw as based at HMS Tamar during teh Korean War, he got polio wnd was assigne dto the Navy Station instead of going to Korea. He was a Lieutenant RNVR George William Maycock. My elder brother Nicholas was born there in 1953 an dhe had quarters on the Peak.

He made reference to an attack on a Patrol Boat by Chinese pirates who slaughtered the crew but I can only find reference to the ML1323 taht was sheleld by Chinese forces. Can anyone enlighten me as to the date, location and casualties involved please.

Many thanks
