David Mercer MacDougall (Chinese: 麥道高; 8 December 1904 – 13 May 1991) was a Colonial Secretary of Hong Kong between 1945 and 1949.
These helped in keeping the local Chinese population on-side, controlling the Triad gangs and identifying Japanese sympathisers.
During the Battle of Hong Kong he worked directly with Admiral Chan Chak who had been brought in to assist in matters of the Chinese public morale and civil order within the British colony.
MacDougall and Chan were among a total of sixty eight British, Chinese and Danish intelligence, naval and marine personnel saved from the Japanese occupation of Hong Kong by a dramatic break-out in five small torpedo boats on Christmas Day 1941.
[1] After Japan surrendered on 15 August 1945 McDougall arrived back in Hong Kong on 7 September 1945 as Chief Civil Affairs Officer with the rank of Brigadier.
