What does the Blaskowitz Map tell us about Portsmouth in the days before the War for Independence? We continue our exploration of the map south of Sprague Street.
What features are marked on the map?
Natural features:
There are two points labeled “Black Point.” One is in the Newtown area and the other is what we call “Black Point” today. “Sandy Point” is what our modern day McCorrie Point is labeled. “Little Sandy Pt.” is our Sandy Point beach area today. Coggeshall Point and Arnold’s Point are on the map. There are two Weaver’s Coves – one in Portsmouth and one at Middletown. The Cove in Portsmouth is by the entrance to Lawton’s Valley.
Man-made features:
There is a Tavern around East Main and Dexter Street. The 1700 Quaker Meeting House is on the map. During the Occupation it was used to house British troops and ammunition was stored in the basement. A fulling mill (to wash and dress wool) was located off of Union Street in the Lawton area. Fogland Ferry is off of Glen Road and heads across to Tiverton. A grist mill (to grind grain) is located within the Glen. Butts Hill is not labeled, but there seems to be troops located there. The orderly rows of dots around the Butts Hill area and to the south of what would be McCorrie Lane today suggest Patriot reinforcements. Blaskowitz’s text mentions that he has included works and batteries raised by the Americans. The location between McCorrie Lane and Glen Road would be a defense against invasion from across the narrow strait of Fogland Ferry. We know that Hessian troops were encamped around there during the Occupation.

Roads: These are listed with the modern names because Blaskowitz did not label the roads.
