He looked eagerly about him, striving to divine the French intentions, but he could make nothing of them.

He believed that the French would withdraw to Crown Point, at least, and might retreat all the way to Canada, leaving Lake Champlain, as well as Lake George, to the complete control of the Anglo-American forces.
