The two key forts captured on Lake Champlain by the Green Mountain Boys were Fort Ticonderoga and Fort Crown Point.

Explanation:

The Green Mountain Boys were a military organization formed at the end of the 1760s in the territory between the provinces of New York and New Hampshire, which later became the state of Vermont. It was led by Ethan Allen.

Some companies of this militia served in the War of Independence of the United States, for example, had a notable role in the capture of Fort Ticonderoga, in the state of New York, on the shores of Lake Champlain on May 10, 1775; the capture of Crown Point; and in the Invasion of Canada that same year. The expenses of this organization were assumed by the Revolutionary Congress of New York.
