Shea successfully demonstrates that more attention should be paid to this understudied Union general. Curtis’ wartime emancipation policies should shift historians’ narrowed focus away from the Eastern Theater to more thoroughly integrate the trans-Mississippi West into their analyses of wartime emancipation. Hopefully, Union General will inspire other historians to incorporate Curtis into the current historiography on wartime emancipation, the Missouri and Arkansas home front, and Civil War memory. Ultimately, Union General is a worthy addition to the scholarship on military leadership and will appeal to readers.
