| First Corps - Army of the Mississippi Major General Leonidas Polk |
This corps of two divisions of two brigades each formed Saturday night column of brigades behind the second line, its center on the main Corinth road, the first division in front. In the advance Sunday morning the head of this corps passed Beauregard's headquarters, at the fork of the Bark and Pittsburg roads, at 7.04 a.m. At the Seay Field Stewart's brigade was detached to the right; Russell's brigade was led directly to the front and became engaged under the personal direction of division and corps commanders. General Clark, commanding the division, led in the charge upon the camp of the Fifty-third Ohio, and soon after passing that camp was wounded and left the field. General Stewart succeeded to the command, but did not bring the division under his immediate orders. General Cheatham, commanding second division, sent his first brigade directly to the front, where it was engaged under Polk's orders. He then took personal direction of Stephen's brigade, conducting it first to the left, and then at 10.30 a.m. to the right center, where he moved to the right and joined General Breckinridge and was engaged at Peach Orchard, and on Monday near the extreme left of the line.
