In Rebels at Sea, best-selling historian Eric Jay Dolin corrects that significant omission, and contends that privateers, as they were called, were in fact critical to the American victory. Privateers were privately owned vessels, mostly refitted merchant ships, that were granted permission by the new government to seize British merchantmen and men of war. As Dolin stirringly demonstrates, at a time when the young Continental Navy numbered no more than about sixty vessels all told, privateers rushed tofill the gaps. Nearly 2,000 set sail over the course of the war, with tens of thousands of Americans serving on them and capturing some 1,800 British ships. Privateers came in all shapes and sizes, from twenty-five foot long whaleboats to full-rigged ships more than 100 feet long. Bristling with cannons, swivel guns, muskets, and pikes, they tormented their foes on the broad Atlantic and in bays and harbours on both sides of the ocean.
