This first full-length treatment of the Revolutionary War battle recounts British general Charles Grey's brutal attack on Anthony Wayne's division of 1,500 Continentals in September 1777. The detailed account follows the action from the arrival of Wayne's division south of the Schuylkill River, near Paoli Tavern, to defend Philadelphia against Howe's encroaching troops to Grey's discovery of Wayne's position, the bloody battle that ensued, and the subsequent court-martial of Wayne, who had been accused of negligence.
