On Sunday morning, the 6th, at about 9 o'clock a. m., I ordered the squadron to deploy as skirmishers on the right flank of our army, to annoy a rebel battery than kept shelling our camps, and at the same time keeping the communications open between the expected re-enforcements under the command of Major General L. Wallace and the army, which position i held against superior force until the arrival of the above-mentioned general, and then i bivouacked for the night in the rear of our right flank.

On Monday morning, the 7th, I received to support a battery under the immediate command of Major-General Wallace. I kept that position during the day, following up the enemy and taking several prisoners. I remained with this division during the night.

Tuesday, the 8th, I received orders to proceed on the road to Corinth; found the enemy in force; returned and reported accordingly.

Casualties during the action: Private Frederick Rhyman, I, Fourth Cavalry, killed, and four horses; wounded, Privates Herberick, Ahrus, McWilliams, Grew, and Hastings, all slightly.
