Eugene Procknow has written a biography of William Hunter--son of a British sergeant who spent his childhood and teen years accompanying the British army, was taken as a prisoner of war, became a printer and returned to America in the 1790s to edit a series of newspapers in Pennsylvania and Kentucky defending freedom of the press before becoming a Jacksonian political figure.  At some point Hunter sat down to write a memoir, which contains one of the few observations by a child of the war, as well as other episodes  of his memorable life, and Procknow has now published a biography, William Hunter:  Finding Free Speech:  A British Soldier's Son who Became an Early American.   
To help with his own research, Procknow has compiled a terrific bibliography of sources on the Revolution, available on his Researching the American Revolution website.
