Ticonderoga in Essex County, New York — The American Northeast (Mid-Atlantic)
Mount Defiance at War
In 1758 British officers and engineers examined Ticonderoga's defenses from low on Mount Defiance prior to the July 8th Battle of Carillon. During the battle, Mohawk, Delaware, and Choctaw warriors allied to the British army, positioned themselves on the mount's lower slopes. They were positioned to fire at the right flank of the French lines across the La Chute River, although they were largely out of range.
During the American Revolution, Mount Defiance received renewed scrutiny for its important location. Although it had not been fortified by the summer of 1776, Deputy Adjutant General John Trumbull felt that Ticonderoga might be vulnerable to guns mounted on Mount Defiance. With Major Ebenezer Stevens, he conducted experiments firing cannon from Mount Independence and Fort Ticonderoga that proved it was within artillery range. Trumbull, accompanied by Benedict Arnold, Anthony Wayne, and others climbed the Mount, finding it challenging, but possible and urged a fortification to be erected near the summit to cover the narrows of the lake. His report was not followed.
Mount Defiance became a critical position as General John Burgoyne's British army encircled Ticonderoga in July of 1777. With astonishing speed, the British surprised the Americans by cutting a road up Mount Defiance and hauling up two 12-pound cannon. The Continentals noticed the British activity and it contributed to their decision to abandon Ticonderoga early in the morning of July 6, 1777, before the British cannon had even opened fire.
General Burgoyne left one British and one Brunswick regiment to garrison the strategic prize, completed the battery on Mount Defiance, and began work on a more permanent blockhouse closer to the summit. Early in the morning of September 18th an American raid led by Colonel John Brown struck the British positions at the Lake George landing. The raiders successfully captured the British post on Mount Defiance and turned the artillery on Fort Ticonderoga. During the ensuing bombardment - the only direct attack on Fort Ticonderoga itself - one Brunswick musketeer in the Fort was killed. Despite controlling Mount Defiance, Brown's men were not prepared for a long siege and faced resistance from the remaining German and British garrison. Brown's men withdrew on September 22nd. Less than a month later, Burgoyne's army capitulated at Saratoga.
With Burgoyne's surrender, the small garrison at Ticonderoga was dangerously exposed and in early November of 1777, they burned the remaining
structures and fell back to Canada. Mount Defiance was garrisoned by Hessen-Hanau Jaegers (riflemen) during the brief capture of Ticonderoga by General Barry St. Leger in late October of 1781, its last military role in the 18th century.
