The American Revolution began with the “Shot Heard Round the World” on the morning of April 19, 1775. Within days of the Battles at Lexington and Concord and subsequent British withdrawal to Boston, over 20,000 men poured into Cambridge from all over New England. Abandoned Tory homes and the empty Christ Church became temporary barracks and field hospitals. Even Harvard College shut down, its buildings becoming quarters for some 1,600 Patriots.
The Continental Congress appointed George Washington General of this “Army” on June 15, two days before the British assault on Farmer Breed’s hill. The action would take its name from that of a neighboring farmer, and went into history as the Battle of Bunker Hill.
Shortly after arriving in July, General Washington discovered that his army had enough gunpowder for nine rounds per man, and then they’d be done.
At the time, Boston was a virtual island, connected to the mainland by a narrow strip of land. British forces were effectively penned up in Boston, by a force too weak to do anything about it.
The stalemate dragged on for months, when a 25-year-old bookseller came to General Washington with a plan. His name was Henry Knox. His plan was a 300-mile, round trip slog into a New England winter, to retrieve the guns of Forts Ticonderoga, and Crown Point.
Washington’s advisers derided the idea as hopeless, but the General approved. Henry Knox set out with a column of men on December 1.
Located on the New York banks of Lake Champlain, Fort Ticonderoga was captured by a small force led by Ethan Allen and Colonel Benedict Arnold, in May of that year. In it were brass and iron cannon, howitzers, coehorns and mortars, 30 pieces in all and another 29, from Fort Crown Point. Arriving on December 5, Knox and his men set about disassembling the artillery, making it ready for transport. A flotilla of flat bottom boats was scavenged from all over the countryside, the guns loaded and rowed the length of Lake George, arriving barely before the water began to freeze over.
Local farmers were enlisted to help and by December 17, Knox was able to report to General Washington “I have had made forty two exceedingly strong sleds & have provided eighty yoke of oxen to drag them as far as Springfield where I shall get fresh cattle to carry them to camp. . . . I hope in 16 or 17 days to be able to present your Excellency a noble train of artillery.”
Bare ground prevented the sleds from moving until Christmas morning, when a heavy snow fell and the column set out for Albany. Two attempts to cross the Hudson River on January 5 each resulted in cannon being lost to the river, but finally Knox was able to write “Went on the ice about 8 o’clock in the morning & proceeded so carefully that before night we got over 23 sleds & were so lucky as to get the Cannon out of the River, owing to the assistance the good people of the City of Albany gave.”
Continuing east, Knox and his men crossed into Massachusetts, over the Berkshires, and on to Springfield. With 80 fresh yoke of oxen, the 5,400lb sleds moved along much of what are modern-day Routes 9 and 20, passing through Brookfield, Spencer, Leicester, Worcester, Shrewsbury, Northborough, Marlborough, Southborough, Framingham, Wayland, Weston, Waltham, and Watertown.
It must have been a sight when that noble train of artillery entered Cambridge on this day in 1776. By March, Henry Knox’ cannon would be manhandled to the top of Dorchester Heights, resulting in the British evacuation of Boston and a peculiar Massachusetts institution which exists to this day: “Evacuation Day”, March 17.
It is doubtful whether Washington possessed either powder or shot in quantities sufficient for a sustained campaign, but British forces occupying Boston didn’t know that. The mere presence of those guns moved British General Howe to weigh anchor and sail for Nova Scotia, but that must be a story for another day.
During WW1, Winthrop Massachusetts artist and bronze foundry operator Henry L. Norton served with the Canadian army “over there” where he was wounded, seven times. In 1926, 150 years after Knox’s march through New York and Massachusetts, Norton and Albany sculptor Henry James Albright designed commemorative plaques to be installed on 56 stone monuments, marking the path of that noble train of artillery. The project was completed in 1927.
Marker locations were updated in 1975 to reflect new research, concerning Knox’s route between Kinderhook New York and Alford, Massachusetts,
A new marker was added in 2009, adjacent to a house owned by General John Thomas at the Roxbury Heritage State Park, in Boston. It was he who guided the weapons from Cambridge to their final placement on Dorchester Heights.
