This engaging and carefully researched book tells, for the first time, the story of William Marsh (1738-1816), an intriguing but little-known Revolutionary figure whose life crossed borders both national and political. It contributes importantly to the literature on American loyalists about whom few book-length biographies have been written. It traces through myriad sources the life of a founder of Vermont long overshadowed by the ample attention paid to his famed associates, Ethan and Ira Allen.

After the war, Marsh documented to the Loyalist Claims Commission the confiscation of most of his Vermont lands and secured grants for himself and offspring in Upper Canada. In the meantime, his father's Vermont holdings preserved a base for the family in their homeland. Returning finally to Vermont, Marsh spent his last twenty years out of the public sphere, rebuilding his life and livelihood among both old friends and enemies, while retain
