Here is an 11-minute travelogue showing the colony in happy times, 3 years prior to hostilities in the Second World War.
On November 16th, 1941, Canadian reinforcements from the Winnipeg Grenadiers and the Royal Rifles of Canada arrived in Hong Kong to bolster the colony’s garrison. The Japanese launched their invasion on December 8th, and three days later, D Company of the Winnipeg Grenadiers became the first Canadian Army unit to see ground combat in the Second World War.
CBC has an interesting audio account from survivors of the battle, along with some interesting nuggets of information. Perhaps most illuminating is the fact that more Canadians sent to Hong Kong died as prisoners of war (550+) than in the fighting (290).
