The Jack Carr Book Club April 2025 selection is THE UNVANQUISHED by bestselling author Patrick K. O’Donnell.
THE UNVANQUISHED pulls back the curtain on a little-known shadow war that raged alongside the Civil War’s better-known battles. At its center: Lincoln’s special forces, the Jessie Scouts—Union soldiers who disguised themselves in Confederate uniforms to carry out daring raids, intelligence gathering, and high-risk missions behind enemy lines.
Through vivid storytelling and never-before-published firsthand accounts, O’Donnell shines a light on the Scouts' deadly cat-and-mouse game with Mosby’s Rangers, uncovering espionage operations, plots to kidnap Abraham Lincoln, and a postwar proxy fight in Mexico.
Patrick K. O’Donnell is a combat historian, public speaker, and the bestselling author of 13 critically acclaimed books spanning from the American Revolution to Iraq. He is a leading authority on special operations and irregular warfare, having embedded with troops in Fallujah and advised on projects like BAND OF BROTHERS and MEDAL OF HONOR. His research blends archival discovery with thousands of oral history interviews, bringing lost stories back to life with intensity and precision.
