Notes from Offbeat, the Police magazine:
After the Japanese surrender in August 1945, Admiral Harcourt of the Royal Navy set up a Military Government in Hong Kong. Mr Pennefather-Evans left for Britain citing health reasons and the British Government appointed Colonel C H Sansom as Commissioner of Police. Colonel Sansom's appointment was a transitional measure in war-ravaged Hong Kong.
At the end of 1946, the British Government appointed as Commissioner of Police the former Deputy Commissioner of Police of Singapore, Duncan MacIntosh. Mr MacIntosh was a man of foresight and progressive instincts. He improved the image and efficiency of the Police Force, whipping the post-war Hong Kong Police Force back into shape. [...]
Contributor Happy Valley notes there's a sketch of DW MacIntosh from his time as a POW, online at: http://www.nas.gov.sg/archivesonline/photographs/record-details/ab4c860…
Comments
Mr. MacIntosh
The gentleman is also remembered by the term “MacIntosh Cathedrals,” the circular 2-storey structures which were erected shortly after WW2 on the Sino-HK border.
These were built to enable the HK Police and the military to conduct surveillance of the border area and to mount anti-illegal immigrant operations in that area.
