French and Indian War James Clinton's military experience began in the
French and Indian War (the North American front of the Seven Years' War), where he served in the
provincial troops of New York in the British cause. He was commissioned an ensign in 1757 and achieved the rank of captain in the New York Regiment in 1759. Commanding a company in 1758, he participated, along with his father (Colonel) and brother George (Lieutenant), in General
John Bradstreet’s capture of
Fort Frontenac (now
Kingston, Ontario). He and his brother played a key role in capturing a French vessel. Clinton remained in the army, and was stationed at various frontier posts. In 1763 he raised and commanded a corps of two hundred men, who were designated as "Guards of the Frontier". After the war, he retired and married Mary De Witt. During the
Saratoga Campaign in 1777, he commanded
Fort Clinton in the Hudson Highlands. He participated in a successful effort to prevent British General Sir
Henry Clinton from rescuing General
John Burgoyne at Saratoga, but he and his troops were unable to hold Forts Clinton and Montgomery. Clinton sustained a bayonet wound in the leg during the assault. In 1778 he was stationed in Albany to oppose Indian and
Tory forces. In 1779, Clinton led an expedition down the
Susquehanna River after making the upper portion navigable by damming up the river's source at
Otsego Lake, allowing the lake's level to rise, and then destroying the dam and flooding the river for miles downstream. This event is described by
James Fenimore Cooper in the introduction to his popular novel
The Pioneers (1823). It is commemorated by an annual Memorial Day canoe race. At
Tioga, New York, Clinton met up with General
John Sullivan's forces, who had marched from
Easton, Pennsylvania. Together, on August 29, they defeated the
Tories and British-allied
Iroquois at the
Battle of Newtown (near today's city of
Elmira, New York). This became known as the "Sullivan-Clinton Campaign" or the "
Sullivan Expedition." They also attacked Iroquois villages throughout western New York, destroying 40 as well as the winter stores of the people. Around 5,000 Iroquois fled to British controlled Niagara and mortality was high that winter because of starvation with several hundred deaths. ==Personal life==
