Twenty-First Brigade - Colonel George D. Wagner (OR Report)
Fifteenth Brigade - Colonel Milo S. Hascall
There will not be individual posts for brigades as there are no brigade monuments. Instead I will simply do posts for the regiments that have monuments.
From Reed's history of the battle:
This division arrived upon the field about 2 p.m. It was ordered into line on Crittenden's right. When it got into position the battle was about over, and only Wagner's brigade became engaged, and that only for a few minutes, the Fifty-seventh Indiana having four men wounded. The division bivouacked in rear of the right of Prentiss'' division camps.
