Goldman, author of the groundbreaking book, "One More War to Fight: Union Veterans’ Battle for Equality through Reconstruction, Jim Crow, and the Lost Cause", discusses how, over four incredible years, raw Northern volunteers evolved into professional soldiers and sailors to rival the finest in the world. In a process that continues to this day, pride in their comrades and units, and what they endured and accomplished together, constituted major components of an evolving, powerful warrior identity.
