Knox, Henry (1750–1806)

US soldier and politician. Having joined the Boston Grenadier Corps in 1772, he became knowledgeable about military tactics and artillery, and he volunteered for the Revolutionary forces at the outbreak of war with England. He soon became a trusted friend and adviser to George Washington and was appointed to command the Continental Army's artillery in November 1775; it was Knox who overcame incredible difficulties in getting the pieces of artillery from Fort Ticonderoga to force the British to evacuate Boston, Massachusetts, in March 1776. From then on he was with Washington in nearly every major engagement of the war, including the crossing of the Delaware to take Trenton, the winter of 1778–79 at Valley Forge, and the final victory at Yorktown.

One of ten sons of a shipmaster who died when Henry was 12, Knox was born in Boston, Massachusetts. He began his career working as a bookseller. Following the American Revolution, it was his suggestion that led to the establishment of a military academy at West Point. He was also a founder of the Society of the Cincinnati in 1783. Knox served as secretary of war from 1785–94, afterward retiring to an estate in Maine, where he lived in great style. He died of complications after swallowing a chicken bone.
