Commander-in-Chief, North America
The office of Commander-in-Chief, North America was a military position of the British Army. Established in 1755 in the early years of the Seven Years' War, holders of the post were generally responsible for land-based military personnel and activities in and around those parts of North America that Great Britain either controlled or contested. The post continued to exist until 1775, when Lieutenant-General Thomas Gage, the last holder of the post, was replaced early in the American War of Independence. The post's responsibilities were then divided: Major-General William Howe became Commander-in-Chief, America, responsible for British troops from West Florida to Newfoundland, and General Guy Carleton became Commander-in-Chief, Quebec, responsible for the defence of the Province of Quebec.
This division of responsibility persisted after American independence and the loss of East and West Florida in the Treaty of Paris (1783). One officer was given the posting for Quebec, which later became the Commander-in-Chief of The Canadas when Quebec was divided into Upper and Lower Canada, while another officer was posted to Halifax with responsibility for military matters in the maritime provinces.
Prior to 1784, the Bermuda Garrison had been placed under the military Commander-in-Chief America, but was subsequently to become part of the Nova Scotia Command until the 1860s.
During the War of 1812, Lieutenant-General Sir George Prevost was Captain-General and Governor-in-Chief in and over the Provinces of Upper-Canada, Lower-Canada, Nova-Scotia, and New~Brunswick, and their several Dependencies, Vice-Admiral of the same, Lieutenant-General and Commander of all His Majesty’s Forces in the said Provinces of Lower Canada and Upper-Canada, Nova-Scotia and New-Brunswick, and their several Dependencies, and in the islands of Newfoundland, Prince Edward, Cape Breton and the Bermudas, &c. &c. &c.
Beneath Prevost, the staff of the British Army in the Provinces of Nova-Scotia, New-Brunswick, and their Dependencies, including the Islands of Newfoundland, Cape Breton, Prince Edward and Bermuda were under the Command of Lieutenant-General Sir John Coape Sherbrooke. Below Sherbrooke, the Bermuda Garrison was under the immediate control of the Governor of Bermuda, Major-General George Horsford), New Brunswick was under Major-General George Stracey Smyth, Newfoundland was under Major-General Charles Campbell, and Cape Breton was under Major-General Hugh Swayne.
Following Canadian Confederation in 1867, these commanders were replaced in 1875 by the General Officer Commanding the Forces (Canada), whose post was succeeded in 1904 by the Chief of the General Staff Canada, a position which was established for a Canadian Army commander.
