In 1776 a massive British fleet of more than 400 ships carrying tens of thousands of soldiers arrived outside New York Harbor. Many of these soldiers were German, hired from their princes by the British government. Americans then and now have called them Hessians. For the next seven years, these German soldiers marched, fought, and suffered seemingly everywhere in eastern North America, from the walls of Quebec City to the sandy beaches of Pensacola Bay. When the British army left, many Germans were left behind–both the living, deserters who had found new lives or others who settled with Loyalists in Canada, and the dead. Just this summer, on the battlefield of Fort Mercer, across from Philadelphia, an archaeological dig discovered a grave with the remains of thirteen German soldiers–and that just a fraction of the Germans who died in that place on October 22nd, 1777. 

With me to describe the Hessians and their American odyssey is Friederike Baer, Associate Professor of History  at Pennsylvania State University, Abington College, and author of the new book Hessians: German Soldiers in the American Revolutionary War.
