special mention for their gallant conduct during the battle of Chickamauga:

Second Lieutenant Wirt Davis, Fourth U. S. Cavalry, commanded the squadron of his regiment which covered the retreat of the Seventh Pennsylvania Cavalry over Reed's Bridge, on the afternoon of the 18th September. This officer has invariably performed his duties in the most satisfactory and gallant manner.

Second Lieutenant J. H. Simpson, Fourth Michigan Cavalry, commanded a squadron of his regiment of picket duty on the Harrison road, on the 18th September, and was cut off by the rapid advance of the enemy. After fighting as long as possible, he swam the Chickamauga, and brought in his squadron with no casualties but 1 man and 1 horse slightly wounded.

I am, respectfully, your obedient servant,

ROBT. H. G. MINTY,

Colonel 4th Mich. Cav.,late Comdg.1st Brig.,2nd Cav. Div.
