Weather historian and reenactor John Horrigan will retrace the “Knox Cannon Trail,” the historic military expedition that helped free Boston from British occupation during the Revolutionary War. He will present a slide show about the amazing engineering feat of Henry and William Knox, whose men and oxen dragged 59 cannons 300 miles in 56 days in 1775 and 1776, culminating in a clandestine battery placement at Dorchester Heights overlooking Boston Harbor. This forced the British to evacuate Boston on March 17th, 1776.Mr. Horrigan will speak at the Westford Museum at 2 Boston Road. This program is not only free to the public, but refreshments will be served.
Mr. Horrigan will also discuss the favorable weather conditions encountered during the operation, a massive blizzard that barely missed Boston in January of 1776 (but gave Quebec twenty-foot snowdrifts!) and a freak gullywasher that hit early on March 6th and thwarted a planned British counter-attack on Dorchester Heights.
