黃泥涌峽
On 18 December, the Japanese had conquered North Point, reaching Wong Nai Chung Gap on the next day. English and Scottish forces and the Canadian Winnipeg Grenadiers vigorously defended the crucial point of Wong Nai Chung Gap, and for a while successfully secured the passage between Central and the secluded southern parts of the island. Japanese casualties were about 600. However, Allied forces there were ultimately defeated by the Japanese on 23 December, and Wong Nai Chung Reservoir was lost – the only one in Hong Kong at the time. As Wan Chai Gap had also fallen that same day, the British had no choice but to surrender.
