GW at American headquarters in Cambridge, Massachusetts. In his General Orders for the day, GW instructed Col. Samuel Gerrish to purchase all livestock in and around Chelsea, Massachusetts.  He also ordered all adjutant generals to inform him of location of their regiments.

Jonathan Trumbull Sr., governor of Conn., wrote GW on this day. In the letter, Trumbull congratulated GW on his election as General and Commander-in-Chief of the army, and gave advice regarding the division of troops in Boston. Trumbull wrote a second letter which warned him of the Congress changing the arrangement of the army’s generals, which could have inconveniences.
