Reserve Corps - Army of the Mississippi
Brigadier General John C. Breckinridge

This corps of three brigades bivouacked Saturday night along the Bark road, between Mickey's and the Pittsburg Landing road, in regular order of brigades, the First in advance and the Third in the rear. At the intersection of the Bark and Pittsburg Landing roads the First Brigade was detached on Sunday morning and sent by main road directly to Shiloh Church. The Second and Third Brigade were led by General Breckinridge along the Bark and Eastern Corinth roads, and were put in position about noon by General Johnston in person, south of the Peach Orchard, where they were first engaged about 1 p.m. General Breckinridge served personally all day with his Second and Third Brigades, uniting them to his First Brigade at the time and place of Prentiss's surrender, and then conducted the entire command to the east along the ridge south of Dill Branch to near the river, where it was under fire from gunboats and batteries. At dark Breckinridge withdrew to encampments of the enemy. On Monday he engaged with his three brigades nearly intact on south side of Corinth road behind Duncan Field, his right joining Hardee about the Peach Orchard. When the army retired Breckinridge formed the rear guard. Morgan's squadron of Kentucky cavalry and Phil. Thompson's company (Kentucky cavalry) were attacked to this corps, but do not appear to have been engaged.
