Washington Taking Command of the Army
Although he did not explicitly seek the office of commander and even claimed that he was not equal to it, there was no serious competition. Congress created the Continental Army on June 14, 1775; the next day, on the nomination of John Adams of Massachusetts, Washington was appointed Major General and elected by Congress to be Commander-in-chief.
