to say that he held to his colors as long as a man would fight with him; also Private Fielder, who took charge of Companies B and G, which were left without a commissioned officer. He led these two companies all day in the thickest part of the battle. The casualties of both days will be given in a supplementary report.

All of which is most respectfully submitted.

I have the honor to be, colonel, your obedient servant,

HDQRS. THIRTEENTH REGIMENT TENNESSEE VOLUNTEERS,
April 10, 1862.

On the evening of April 2, in obedience to orders, I caused to be put in motion the Thirteenth Regiment in the direction of Pittsburg, in the vicinity of which place I encamped on the night of the 5th.

The next morning I advanced upon the enemy, who was strongly posted with a battery of six guns, commanding every avenue of approach, and supported by strong detachments of infantry. While in this position I was told by General Bragg that this battery was a source of great annoyance to our troops, and that it must be taken at all hazards. I was ordered to take this battery by a right flank movement. I had proceeded but a short distance when I discovered that I would be exposed to a heavy fire from two of the enemy's camps.

At this time heavy firing commenced on our right, and I was ordered to support it. I did so, when I met with General Cheatham, who ordered me to remain where I was until further orders.

It being now near about dark, I was ordered to fall back to an encampment, where we took up quarters for the night.

Early next morning I took position in line of battle and under the immediate command of our brigade commander; remained but a short time before we discovered the enemy making a flank movement on our left; planted a battery, which opened a deadly fire upon us, when we fell back out of range of the battery.

At this time, my horse being disabled by a cannon-shot, I was dismounted, and turned the command over to Lieutenant-Colonel Morgan, who reformed the regiment and took position to the rear, when I wan again mounted and resumed command. I then, under the immediate
