Alabama native John Gregg (1828-1864) moved to Texas, served in that state's secession convention and the Provisional Confederate Congress, was elected colonel of the 7th Texas Infantry, and was promoted to brigadier general in August 1862. During the Vicksburg Campaign, he commanded the forces at the Battle of Raymond on May 12, 1863. His brigade was transferred to Longstreet's Corps and fought at Chickamauga, where he was wounded on September 19, 1863. After recovering, he took command of Hood's Texas Brigade in the Army of Northern Virginia. At the Battle of the Wilderness on May 6, 1864, his brigade, leading Longstreet's Corps, arrived in time to blunt a major Union assault that had collapsed A. P. Hill's Corps on the right flank, and his counterattack saved the army from destruction. During that action, General Robert E. Lee appeared to be personally leading the Texans into battle, prompting the cry "Lee to the rear!" through the brigade. Gregg was killed on October 7, 1864, and was buried here on March 27, 1865.
