The War Office, also once known as the Capt. Joseph Trumble Store and Office, is a historic commercial building on the Lebanon Green in Lebanon, Connecticut. It is located near the Governor Jonathan Trumbull House, a National Historic Landmark. It is a 1-1/2 story gambrel-roofed wood frame structure, built c. 1732 by Captain Joseph Trumbull as a place from which to conduct his merchant business. The building is most significant for its use during the American Revolutionary War. It served as the war office of Connecticut Governor Jonathan Trumbull, with more than 1,000 councils of war taking place there. Visitors to the office included George Washington, Rochambeau, Lauzun, Lafayette, Admiral de Ternay, Generals Henry Knox, John Sullivan, and Israel Putnam, also Thomas Jefferson, Benjamin Franklin, John Adams and John Jay. The Lebanon Green was also where cavalry of the French Army wintered in 1780-81, before joining the rest of their army for the march to Yorktown, Virginia in 1781. The War Office was, like the Trumbull House, moved a short distance in 1824. It is now part of the museum property managed by the Connecticut chapter of the Daughters of the American Revolution that also includes the Trumbull House and the Wadsworth Stables.
