Edmonston House / Knox's Headquarters

The Edmonston House, built in 1754, was used as a headquarters during the American Revolution by Continental Army General Henry Knox, one of George Washington's closest aides.

Knox was a Boston bookseller who became Washington's artillery chief during the Revolutionary War.

Knox became an instant war hero when he helped end the British siege of Boston in 1776. His first assignment, after being named a colonel by Washington, was to go to Ticonderoga and retrieve captured British guns to fight the redcoat stranglehold on Boston.

With sleds and oxen in the dead of winter, Knox's troops ferried almost 120,000 pounds of captured British artillery 300 miles through the mountains to Boston. Once in Boston, the artillery pieces appeared throughout the hills surrounding the city, forcing the British to retreat from their own lost weaponry.

The British retreated to Nova Scotia, and with Knox, Washington found someone he could rely on for the remainder of the war.

After the war, Knox succeeded Washington as commander-in-chief and later became the first secretary of war in Washington's cabinet.
