On this day 250 years ago in Newbury, New Hampshire (now Newbury, Vermont) Captain Thomas Johnson, Frye Bailey, Abial Chamberlain, Silas Chamberlain, and John McLean of the Newbury militia guided by Bill Heath of Rumney, New Hampshire set out on snow shoes to blaze a route to St. Johns, Lower Canada, (now Saint-Jean-sur-Richelieu, Québec) following Indian trails. This was the beginning the beginning of the Bailey-Hazen Military Road, originally authorized by General Washington as a supply route to the Continental Army in Quebec. Johnson recorded in his diary:

Tuesday, March 26. Set out from Newbury, lodged at the last inhabitant’s. . . . waited half a day for the rest of the soldiers to come up; good land for a road. Wednesday, 27. Marched a mile, good country

Frye Bailey and Abial Chamberlain would go on to distinguished service as officers in the Continental Army for the remainder of the War.

On this day 250 years ago in Nantasket Roads off the coast of Massachusetts, the British fleet at long last departed for Halifax, Nova Scotia, never to return in force. The British left only a few ships behind to intercept any supply ships from Britain headed for Boston to redirect them to Halifax, and to cruise for American ships to capture.
