About Douglas Cochrane, 12th Earl of Dundonald

Lived 1852 – 1935 (aged 82). Douglas Cochrane, 12th Earl of Dundonald was a British military personnel and politician.

Lieutenant-General Douglas Mackinnon Baillie Hamilton Cochrane, 12th Earl of Dundonald, (29 October 1852 – 12 April 1935), styled Lord Cochrane between 1860 and 1885, was a British Army officer and politician.

Early life Cochrane was the second but eldest surviving son of Thomas Cochrane, 11th Earl of Dundonald, by Louisa Harriet Mackinnon, daughter of William Alexander Mackinnon. Thomas Cochrane, 1st Baron Cochrane of Cults, was his younger brother. He was educated at Eton College.

Military career

In April 1902, it was announced that Lord Dundonald would be appointed General Officer Commanding the Militia of Canada, the senior military officer in Canada. He left Liverpool on 15 July, and arrived in Quebec and Ottawa later the same month to take up his position. He and his family stayed at Crichton Lodge in Rockcliffe, Ottawa, Ian McAllister of Morton College, Oxford was appointed as his private secretary whilst in charge. During his time at Canada, he authored a scheme for the reorganisation of the Canadian militia on entirely new lines, which was adopted, he also wrote a drill and training book, directed towards Cavalry and infantry, additionally, he revamped the cadet corps structure and established several other associations aimed at enhancing the militia. He was also able to change the dress codes of many Scottish regiments to align more with their culture. He served in Canada for two years until he was dismissed by the dominion cabinet due to his outburst at a dinner in Montreal, described as "utterances at a banquet" in newspaper articles and officially termed "Indiscretion and insubordination" by the cabinet. In defence of his critics, Dundonald asserted that communication between him and the minister of the militia had been corrupted which left Canada defenceless.
