Colin Hercules Mackenzie, CMG (1898–1986), a soldier, industrialist, and aesthete, was a Special Operations Executive spymaster who led Force 136 throughout the period of its existence during the Second World War. Origins Mackenzie was the son of Major-General Sir Colin Mackenzie and Ethel Ross, the daughter of Hercules Grey Ross ICS and granddaughter of the sportsman and photographer Horatio Ross. Of Scottish ancestry on both sides of his family, he had the peripatetic childhood typical of many children of British Army officers. Education After Summer Fields and Eton (where he was a King's Scholar), Mackenzie was commissioned into the Scots Guards and was badly wounded at the very end of the First World War, undergoing a series of amputations of his leg in an ultimately successful battle against gangrene. Following the war, Mackenzie went up to King's College, Cambridge. On informing the Provost that he had forgotten his Latin and proposed to read English, Mackenzie was told that "English is a grubby subject" and elected instead to read economics. His tutor was John Maynard Keynes and he graduated with a first-class degree, having also won the Chancellor's Medal for English Verse. He later maintained that Keynes's most useful advice to him had been: "If a book is worth buying at all, it is worth buying in red Morocco." Between the wars After Cambridge, Mackenzie worked for J. and P. Coats in Glasgow. He became a director and played a leading part in the company's global expansion, in particular into South America. In the 1920s he had an intense epistolary relationship with the writer Iris Origo. Spymaster During the Second World War, at the suggestion of his friend Lord Linlithgow, Mackenzie was appointed to set up a Far Eastern mission for Special Operations Executive, which became known in due course as Force 136. Unusually for senior SOE personnel, he remained in his post to the end of the war, despite the numerous political and other challenges that he faced. An official SOE report in 1944 recorded that: No one can visit India without being impressed by Colin Mackenzie; by his exceptional grip on the working and personnel of his group; by his capacity to simplify and without delay go to the root of any problem; and by his remarkable sense of timing and diplomacy.
