This book critically examines archival materials to investigate the driving force behind the 1779 Sullivan-Clinton Campaign: the destruction of Iroquoia. This book shows that these coordinated attacks were designed to destroy Haudenosaunee political cohesion, clear the Indigenous population from the land, and replace it with a non-Indigenous one. In 1778, George Washington, Philip Schuyler, army officers, and New York officials began planning invasions against Iroquoia, the homeland of the Haudenosaunee and several other allied Indigenous nations. This invasion was one of the largest American offensives of the Revolutionary War, curated to punish the Haudenosaunee for raids against frontier settlements in New York and Pennsylvania. However, the resulting 1779 campaigns of Goose Van Schaick, Daniel Brodhead, and Generals John Sullivan and James Clinton were not simple retaliation. Clearing Iroquoia: New York’s Land Grab in the 1779 Campaigns of the American Revolution by Travis M. Bowman and Matthew A. Zembo critically examines archival materials from these campaigns to investigate the driving force behind the campaigns: removal. Through their research, Bowman and Zembo explore how colonial leaders ignored peace efforts and how George Washington ordered his officers to do the same – prioritizing the destruction of Iroquoia and placing native peoples at the lower end of a racial hierarchy to justify their actions. Using letters, journals, speeches, and reports, this book brings the buried truths to light, exploring these series of coordinated attacks that were designed to destroy Haudenosaunee political cohesion, clear the Indigenous population from the land, and replace it with a non-Indigenous one.
