Few infantry regiments in the Civil War compiled a more distinguished record than the Fifth Missouri. The unique blending of fiery Irish Confederates from St. Louis with rural pro-Southern Missourians forged an unshakable esprit de corps, making the unit the crack infantry regiment in the western sector. Most of Colonel James C. McCown's troops were young men in their 20s, and their good health and physical conditioning allowed them to carry out their "shock" missions throughout the region. From the perspective of the common soldiers and the unit's leaders the activities and battles of the Fifth Missouri are recounted here.
