Description: Revolutionary War researcher and weather historian John Horrigan will retrace the steps of a historic military expedition that helped free Boston from British occupation during the Revolutionary War. Horrigan will present a slide show about the amazing engineering feat undertaken by the Knox brothers (Henry and William) in the Winter of 1775-76. The brothers used 80 yoke of oxen to drag 59 cannons a total of 300 miles in 56 days, which culminated in a clandestine battery placement at Dorchester Heights overlooking Boston Harbor. This swayed the British to evacuate Boston on March 17th, 1776. Mr. Horrigan will also discuss the favorable weather conditions that the expeditionary force encountered during the operation. He'll digress about a massive blizzard that just missed Boston in January of 1776 - but gave Quebec and the besieged Benedict Arnold expedition twenty-foot snowdrifts! John will expound upon a freak 'gullywasher' that hit Boston early on March 6th, 1776 and consequently thwarted a planned British counter-attack on Dorchester Heights. Because his marines were ill from the rolling sea conditions, General Howe then decided to evacuate his 7,000 troops from Boston and relocate them to Nova Scotia. John has a version of this lecture ("Evacuation Day For Kids") that is a good learning tool for students ages 9 through 15 as it gives a broad and basic background of the American Revolution. Listen to the speech in the audio archive.
