"Our regiment, after the battle of Pittsburg Landing, was detached from the Western army and ordered to the Potomac. We had scarcely been there a week before we were sent out on a scout, with orders to capture Mosby, who was constantly harassing us, and scatter his command. We were out about ten days, without accomplishing our object. Not a single glimpse did we get of a reb, and finally we turned our faces toward the camp. Our horses, as well as ourselves, were nearly jaded, and the way we do there, when a horse gives out, is to put a bullet through his head, shoulder our saddles, and trudge along after the column on foot, until we can find another animal to ride. I had command of the rear guard; and when we had arrived within a day's march of camp, my horse suddenly gave out--laid right down in the middle of the road, and couldn't go a step further. I was in something of a fix, and my feelings were none of the pleasantest when I found myself sprawling in the dusty road, and saw that my horse was used up. It was something of an undertaking to find my way back to camp, through a country infested with guerrillas, and with which I was entirely unacquainted. It is true that I could have had a horse, as several were at once offered me by my men; but I could not be mean enough to save my own bacon by leaving one of those brave fellows behind; so I told Ben to go ahead with the company, keeping a good look-out for a horse, and if he could find one, to send it back to me. I then shot my animal; and it was a job I hated to do, I tell you, for he was as fine a horse as ever stepped; he had carried me many a long mile, and being my constant companion for almost a year and a half, I had become very much attached to him. But there was no help for it; our orders were strict; and I shouldered my saddle, and marched after the column, which was soon out of sight. "I walked along at a pretty lively pace, keeping a good look-out on each side of the road for horses, and now and then looking behind, half expecting to see a squad of Mosby's cavalry in pursuit, until I was startled by the report of a pistol directly in front of me, and, coming suddenly around a bend in the road, I found Ben sitting beside his horse, which had also given out, waiting for me to come up. As I approached, glad enough that I was not left to find my way back to camp alone, Ben picked up his saddle, and glancing sorrowfully at the work he had done, said: "'There's an end of poor Thunderbolt--the best horse in the regiment. It has no doubt saved him many a long scout, but I never felt so sorry for any thing in my life.'
