The Battle of Split Rock is really just a continuation of the Battle of Valcour, and a lot of it takes place in a location called Button Mould Bay (or Buttonmold Bay).

So why is it called the Battle of Split Rock?

That’s a fine question. On the western shore of Lake Champlain, just north of Button Mould Bay, is a formation called Split Rock Mountain. It rises sharply from the lake to an altitude of just over 1000 feet, and it’s where the confrontation between the British and the Americans resumed.

Button Mould Bay is an area of shallower water on the opposite side. It gets its name from a series of clay masses which have hardened almost to the point of concrete, into a shape much like an oversize button, or like the molds used in button making. Those concretions actually made it easier for Benedict Arnold to run his ship, and the galleys accompanying him, aground and set ablaze. This was the ship that had all of Arnold’s papers on it that I told you about the other day.
