HENRY, Alexander, traveller, born in New Brunswick, New Jersey, in 1739; died in Montreal, Canada, 4 April, 1824. He accompanied the expedition of Sir Jeffrey Amherst in 1760, and was present at the capture of Fort de Levi, on the St. Lawrence river, and the surrender of Montreal. A new market having been thus thrown open to English merchants, Henry embarked in the fur-trade, and in 1761 went to Fort Mackinaw. On 4 June, 1763, the majority of the garrison were massacred by the Indians, and Henry, with others, was carried into captivity, but finally escaped death by the intervention of Wawatam, a Chippewa, who had previously adopted him as a brother. Henry now assumed the Indian garb, and lived among the savages till June, 1764, when he went to Fort Niagara, and was given the command of an Indian battalion of ninety-six men, with which he accompanied the army of General John Bradstreet to Detroit. After the relief of that city and the flight of Pontiac, Henry resumed the fur-trade, and until 1776 travelled in that employment in the northwest, between Montreal and the Rocky mountains. In 1770, with the Duke of Gloucester and others in England, and Sir William Johnson, Henry Bost-wick, and a Mr. Baxter, in the colonies, he formed a company for working the mines on Lake Superior, but after various unsuccessful attempts the company was dissolved in 1774. Masses of copper weighing as much as three pounds were found, but Henry concluded that the " copper ores of Lake Superior can never be profitably sought for but for local consumption. The country must be cultivated and peopled before they can deserve notice." Henry published "Travels and Adventures in Canada and the Indian Territories between the Years 1760 and 1776" (New York, 1809).
