Major General John S. Bowen’s Missouri Confederate command is presented through the organization and casualties of its First and Second Brigades and attached batteries during the Vicksburg campaign. In the First Brigade under Colonel Francis M. Cockrell, the First and Fourth Consolidated, the Second, the Third, the Fifth, and the Sixth regiments each suffered heavy killed, wounded, and missing, and numerous officers were killed or mortally wounded, including Colonel A.C. Riley, Lieutenant Colonel Pembroke S. Senteny, Captain William P. McIlvane, Colonel Eugene Erwin, and others. Guibor’s Battery, Landis’ Battery, and Wade’s Battery also sustained losses, while Colonel William Wade was killed at Grand Gulf on April 29 and Captain John C. Landis acted as division chief of artillery from May 13. In the Second Brigade, Brigadier General Martin E. Green was killed in the trenches on June 27, and the brigade included the First Cavalry dismounted, the Third Cavalry Battalion dismounted, the Third Battery, Lowe’s Battery, Bledsoe’s Battery, and Clark Artillery. Additional losses at Grand Gulf on April 29, at Port Gibson on May 1, and at Big Black River Bridge on May 17 could not be distributed among the several Missouri Confederate regiments and batteries engaged and were therefore excluded from the individual command totals, except where specifically noted.
