The Battle of Wong Nai Chung Gap was the largest sustainment of casualties in a single day, on both sides, in the whole conflict. Its subsequent capture by the Japanese effectively led to the downfall of Hong Kong Island, splitting the forces there in two (Separating East/West Brigades). At the time of this Battle, the Wong Nai Chung Gap area included defenders of the Middlesex Regiment, The Winnipeg Grenadiers and the HKVDC. Canadian Army Brigadier John K. Lawson was present at the HQ and involved in the Battle.
