[CIVIL WAR]. BEAUREGARD, Pierre G.T. General C.S.A. Autograph letter signed ("G.T. Beauregard") to an unknown correspondent, Charleston, S.C., 25 November 1862. 1 page, 12mo, unevenly trimmed at lower margin. BEAUREGARD SENDS PLANS OF SHILOH. On the morning of April 6, a Confederate army had surprised Grant's forces in camp; command fell to Beauregard after Gen. A.S. Johnston was killed. That evening Beauregard halted what should have been the final attack, believing Grant could not be reinforced in time to prevent a decisive rebel victory. The timely arrival of Union reinforcements under Buell enabled Grant to regain the initiative and force Beauregard to withdraw. Assigned to a new post defending the Carolina and Georgia coasts, Beauregard encloses "a copy of the Plans of the Battle of Shiloh made to accompany my Report of said Battle. It will enable you better to understand my explanation of the other day. With my best respects to Mrs. B."
