On December 12 Kerck Kelsey presented “A Tale of Two Cavalry Raids” that compared and contrasted Col. Abel Streight’s raid into Mississippi and northern Alabama and Col. Benjamin Grierson’s raid into central Mississippi. The bold incursions deep into Confederate territory had common objectives, to cut critical rail lines and stymie the resupply of Confederate forces operating in the western theater. The two raids also revealed important variables – the consequence of command decisions, military preparation, and ingenuity. Col. Streight’s raid would end in a tactical failure. Col. Grierson’s raid was a tactical success. But both raids, in their own way, facilitated General Grant’s victory at Vicksburg, a conspicuous strategic victory. Many thanks to Kerck for sharing his insights.
