In The First Fleets, Benjamin C. Schaffer reveals how, contrary to widespread beliefs, the American colonies had a long tradition of independent naval defense decades before the Revolution. He demonstrates that Anglo-American governments established and maintained significant provincial naval forces and that the history of provincial navies illuminates broader aspects of colonial history and the colonies' ultimate break with the British Crown. Based on meticulous research, Schaffer recounts the sea-borne threats that American colonies faced from the French, Spanish, pirates, and others. He reviews colonial governance and the relationships between colonial governments and Great Britain. Highlighting Britain's scant naval power in North America, Schaffer demonstrates how the vulnerable coastal colonies undertook their own self-defense.

Schaffer's study offers many fascinating episodes from colonial history. Establishing a navy was controversial in pacifist-minded, Quaker-dominated Pennsylvania. South Carolina deployed its scout-boat navy to pursue enslaved Africans who fled colonial capture. The first paper money issued in North America was an initiative to pay for a naval expedition against French Quebec. These and other episodes show the intimate connection between these little-known provincial navies and the major sociopolitical developments of their day.
