What Can't Brave Men Endure? marks Joseph Lee Boyle's second book dedicated to resurrecting the identities of the heroes of the six-month encampment of the Continental Army at Valley Forge in 1777-1778. His previous volume, Fire, Cake, and Water, identifies the Connecticut soldiers who were among the 30,000 individuals whose names appear on the surviving monthly muster and payroll records for the beleaguered Valley Forge encampment. Boyle's latest volume examines the New Jersey contingent. Like his earlier Connecticut volume, however, What Can't Brave Men Endure? is composed essentially of an alphabetical list of some 2,500 New Jersey soldiers abstracted from Revolutionary War muster and payrolls at the National Archives. Each patriot is identified by name, rank, date and term of enlistment or commission, names of regiment and company, and a variety of supporting details, such as date of furlough or discharge, when wounded, when and where promoted, etc.
