This plan of Kennebeck & Sagadahock Rivers & country adjacent

Just a year after producing a map supporting the Brunswick Proprietors’ claim, Thomas Johnston issued this plan supporting the position of their opponents in the Plymouth Company. The map depicts the Company’s grant extending to Casco Bay and includes a long note justifying its title to the land. It also places the dispute in the broader context of Anglo-French tensions by highlighting the Company’s role in establishing Forts Franckfort and Western to protect the Maine frontier from French attacks.
