Colonel Lyons.
Fort Donelson, August 3, 1863.—I have finally applied for a leave of absence. I have but little hope of getting it . If granted, I can not go to Racine before the 20th.
Mounted infantry from Clarksville were here on Thursday, and on their way home were fired into by guerillas in ambush about eight miles from here, and five of them badly wounded. One has since died and another will die. One of my companies, commanded by Hollister, was in that section and went after them, driving them several miles.
