In the winter of 1775–1776, General Henry Knox passed through this place while delivering to General George Washington at Cambridge the train of artillery from Fort Ticonderoga that was used to force the British Army to evacuate Boston. Erected by the Commonwealth of Massachusetts in 1927, this monument is dedicated to the thousands of innocent and brave men, women and children killed by terrorist attacks in New York City, Washington D.C. and Pennsylvania on September 11, 2001. They died for our country and our freedom. We shall not forget.
