I cannot find the note, but my answer I have kept: Chewalla, Jane 6, 1862.
Major-General GRANT.
My DEAR SIR: I have just received your note, and am rejoiced at your conclusion to remain; for you could not be quiet at home for a week when armies were moving, and rest could not relieve your mind of the gnawing sensation that injustice had been done you.
My orders at Chewalla were to rescue the wrecked trains there, to reconnoitre westward and estimate the amount of damage to the railroad as far as Grand Junction, about fifty miles.

We camped our troops on high, healthy ground to the south of Chewalla, and after I had personally reconnoitred the country, details of men were made and volunteer locomotive engineers obtained to superintend the repairs.

I found six locomotives and about sixty cars, thrown from the track, parts of the machinery detached and hidden in the surrounding swamp, and all damaged as much by fire as possible.

It seems that these trains were inside of Corinth during the night of evacuation, loading up with all sorts of commissary stores, etc., and about daylight were started west; but the cavalry-picket stationed at the Tuscumbia bridge had, by mistake or panic, burned the bridge before the trains got to them.

The trains, therefore, were caught, and the engineers and guards hastily scattered the stores into the swamp, and disabled the trains as far as they could, before our cavalry had discovered their critical situation.
