Near Prairie Mound, Chickasaw County
April 27, 1863
Brigadier-General Chalmers
   My information this morning is that the enemy was last evening southwest of Houston; would probably take the Pittsborough road, and endeavor to escape between Pontotoc and Oxford {on the Mississippi Central RR}. The force of the enemy is small, not exceeding 250. The main column has been driven back. The damage done to the Southern Railroad is not as extensive as first reported. The enemy did not get to the Mobile & Ohio Railroad. Cars came up from Meridian this morning. I will send you all the information of the enemy's whereabouts I may be able to get, and will keep in the most perfect readiness to act where it may be necessary. I will send one command on to the Pontotoc and Houston road; will keep one here, and Major Inge at Okolona {on the Mobile & Ohio RR}, to scout down the railroad until it fully appears no longer necessary.
I am, sir, your obedient servant,
C. R. Barteau
