Lieutenant Governor and Superintendent of Indian Affairs at Fort Detroit In 1775, Henry Hamilton was appointed as Lieutenant Governor and Superintendent of Indian Affairs at
Fort Detroit,
Province of Quebec (it then extended from the Atlantic to this area),
British North America. (The fort site is now within the borders of
Detroit, Michigan). This was one of five newly created lieutenant governorships in the recently expanded eastern territory of Canada. When Governor Hamilton reached his base at Fort Detroit to assume his government duties in the
Great Lakes region, the American Revolutionary War was already underway. Hamilton was in a difficult position: as a civil official, he had few British Army regulars at his command, and the loyalty of local
Canadians and
Indians was far from assured.
Normand Macleod, a local fur trader and army officer, acted as the temporary "town major", a British government official in command of a fortified town, before Hamilton's arrival.
British war policies on the western frontier Governor Henry Hamilton became adept at diplomacy with the Indians, establishing good relations with local Indian leaders of the Huron and Odawa tribes. An amateur artist, Hamilton also sketched portraits of many Indians while in Detroit, leaving what has been called the "earliest and largest collection of life portraits of Native Americans of the Upper Great Lakes." This is now held by Houghton Library at Harvard University. At the beginning of the war, British policy encouraged neutrality among the Indians leaders. But in 1777 Hamilton received instructions to encourage Indian raids against American frontier settlements in
Pennsylvania,
Virginia, and
Kentucky. Hamilton responded to
Lord Germain, "Would to God this storm which is ready to fall on the Frontiers could be directed upon the guilty heads of those wretches who have raised it, and pass by the miserable many who must feel its fatal effects." This was a controversial policy, because he and other British officials realised that
Loyalists would inevitably be killed in these raids. Hamilton tried to limit civilian casualties by sending British Army regulars and Canadian militia alongside Indian raiding parties. Despite this, Indian warriors carried out their own customs during the raids, resulting in hundreds of women and children in
Kentucky and western Pennsylvania being killed and
scalped during the war. This, as feared, led to an increase in anti-British sentiment in the region. According to an early 20th-century local history, Americans on the frontier accused Hamilton of paying bounties for prisoners and scalps brought in by the Indian warriors, calling him the "Hair-buyer General". Hamilton denied ever paying Indians for scalps. He did, however, accept scalps as evidence of success, for which Indian war parties were rewarded with additional supplies.
George Rogers Clark and Illinois Regiment, Virginia state forces in the Illinois Country In 1778, Patriot Colonel
George Rogers Clark, commanding Virginia state forces, captured several undermanned British posts in the
Illinois Country, including
Fort Sackville at
Vincennes (then in Virginia-claimed land, now in present-day Indiana). Hamilton led an armed party from Detroit on 7 October 1778 to recapture the British post, 600 miles away. His small force gathered Indian warriors along the way, and entered Vincennes on 17 December 1778. They captured Fort Sackville and the American commandant, Captain
Leonard Helm. In February 1779, however, Colonel Clark returned to Vincennes in a surprise march, recapturing the outpost and taking Hamilton prisoner.
Defeat and prisoner in Virginia In early March, General George Rogers Clark ordered Hamilton to be taken to the Virginia state capital in
Williamsburg as a prisoner of war. Poor travel conditions on the Ohio River forced the group—led by Captain Williams and Lieutenant Rogers—to travel most of the way by foot through the Moccasin Gap between what is now Kentucky and Virginia, finally arriving in Williamsburg in the middle of June. Once in Virginia's capital, he was jailed and placed in irons by order of Governor
Thomas Jefferson and the Virginia Executive Council. Hamilton was held from 16 June – 29 September 1779. Hamilton rejected an offer of parole on the grounds that the terms violated his freedom of speech in restraining him from "saying anything to the prejudice of the United States." Jefferson refused to treat Hamilton and other British prisoners as
prisoners-of-war and handled them as he would have handled escaped slaves: putting them in irons for 18 months in Williamsburg and Chesterfield. Governor Jefferson eventually dropped charges of scalp-buying, but did not release Hamilton until October 1780, and only after
George Washington during several months had entreated him to accept his parole. Hamilton was sent to New York to await a prisoner exchange. This took place in March 1781. He immediately sailed to
London, England on a British ship. ==Later career as British royal governor==
