Washington's Headquarters at Cambridge, 1775
Washington used the home as his headquarters and home while he planned the Siege of Boston between July 1775 and April 1776. During his time there, Washington was visited by John Adams and Abigail Adams, Benedict Arnold, Henry Knox, and Nathaniel Greene. Martha Washington joined her husband in December 1775 and the two stayed in the house until March 1776. On Twelfth Night in January 1776, the couple celebrated their wedding anniversary in the home.
