Wong Nei Chong Gap PB 3, Wong Nei Chong Gap [1940- ]
This pillbox is shown as 'PB3' on a hand drawn map included in the War Diary of Major E.G. Stewart. I'm not sure if 'PB3' was the 'official' reference for the pillbox or just his personal numbering system, as there was another Pillbox number 3 on the Western shore of HK island, between Sandy Bay and Telegraph Bay.
The pillbox overlooks Wong Nai Chung Gap, one of the fiercely contested areas during the war. It is mentioned in the diary entry for 0645 on December 19th:
Enemy rushed Wong Nei Chung Gap and Police Station Knoll. Message to Field, "Enemy massed below Police Station in Gap." Field opened fire with great accuracy despite poor visibility, target being in the shadow. Enemy again caught 'en masse' and casualties heavy. L/Cpl Lau's section also opened fire. PB3 on Black's Link, close to Gap, did not open fire, for some unexplained reason - possibly not occupied!
