When the South bombarded Fort Sumter in April 1861, the Ellithorpe family in rural New York answered President Lincoln's call to defend the Union. For the next four years, the two Ellithorpe brothers and two of their brothers-in-law fought in some of the Civil War's most storied regiments, on nearly every major battlefield in the East. In this utterly unique Civil War historybiography, John A. Simpson reconstructs the intertwined lives and wars of four Union soldiers, from Bull Run to Gettysburg and beyond.
