The British at Saint-Jean and the Americans at the other end of the lake [Champlain] in Skenesborough (present-day Whitehall, New York. While planning Quebec's defenses in 1775, General Carleton had anticipated the problem of transportation on Lake Champlain, and had requested the provisioning of prefabricated ships from Europe. By the time Carleton's army reached Saint-Jean, ten such ships had arrived. These ships and more were assembled by skilled shipwrights on the upper Richelieu River. Also assembled there was HMS Inflexible, a 180-ton warship they disassembled at Quebec City and transported upriver in pieces.
"Rabble in Arms" by Kenneth Roberts is a tremendous tale of the subsequent battle on Lake Champlain and the retreat south.
Yes, he was a tremendous writer. I grew up readign all his historical novels..sadly, 99% of kids today have no idea who he was or of his books..BTW..”Drums Along the Mohawk” is a superb adaptation of the book to the big screen...
