The regiment reached La Grange on the 20th instant, and their camp near Memphis on the 23d, making thirty days on the expedition, and marching a little over 300 miles. During most of the time we were able to procure about two -THIRDs rations of forage for our horses, mostly sheaf oats, wheat, and rye, with an occasional feed of corn. Our total loss in men has been 1 killed and 15 wounded. Loss of horses, killed and abandoned, 16.

In closing this report, I desire to express my many obligations to Major A. R. Pierce, for his promptness, energy, and good judgment, and to all the officers and men of the regiment for their cheerful acquiescence and ready obedience to orders, their prompt response when at times it seemed that their physical energies had been taxed to their utmost tension.

I have the honor to be, very respectfully, your obedient servant,

J. H. PETERS,

Lieutenant-Colonel, Commanding Fourth Iowa Cavalry.
