Considered one of the most stupendous logistical feats of the American Revolution, an expedition organized by Col. Henry Knox transports fifty-eight tons of brass and iron weaponry from Fort Ticonderoga (where they had been left behind by the British) down the Hudson River, over the Berkshire hills, across today’s Massachusetts to Cambridge, and finally to Dorchester Heights overlooking Boston. Author Mary Ames Mitchell, a former elementary school teacher and a descendant of Henry Knox, wrote and illustrated this story as a sing-along ballad for her grandchildren.
