Correspondence of (ho GazetteLetter from the 70th Indiana.Field Hospital, May 17th, 1804.Fiukxd Callls :—In order to eorroctany false reports that may be circulated in relation to the late casualities in the 70th Indiana, 1 will endeavor to give you the facts pertaining' to the ease. On Saturday and Sunday we were under a hot lire for seven hours. On Saturday the regiment lost 3 killed and J3 wounded : Killed, Win. W. Weaver; wounded, .John It. Asher and Daniel Davidson—from Morgan county.— Davidson’s wound was very slight, and he is now waiting on his wounded companions in the hospital. Sunday’s tight commenced about half-past one o’clock in the afternoon, where the rebels had repulsed our men the evening before. (Jen. Hooker moved his corps from the centre to the extreme left, at which time we were all formed in line of battle by battallions on masse, at forty paces, with bayonets fixed. Our brigade was in the centre; 3d brigade, on the left; 2d brigade, Col. Coburn, oil our right. The old 70th went in gallantly, led by our noble Colonel. Gen. Hooker'says there never was such successful fighting, under so murderous a lire, as we made. I will now give you the names of the killed and wounded belonging to Co. 11.. from Morgan county, during the two days’ lighting : Killed, Scrgt. W. II. Gibbs, private Win. W. Weaver. Wounded : Corporal II. Cox, privates W. S. Cramer, John B. Asher, E. L. Kay, Hiram Yoyles, itobcrb Wheeler, John T. Hammans and Daniel Davidson. I was also wounded—shot just below the knee, and got a slight rip in tlie side with the beak of a musket. My sword was knocked out of my hand, either with a canister or a piece of shell. Lieut. Record is safe. While I was being carried olf the field, he was rallying Co. JL, to “ go in on their muscle.” Hammans’ wound was but a slight scratch, and lie has re-joined his company. As I am suffering considerably from pain, T am unable to give you further particulars. 1 hope the sympathies of our friends arc with us all, both well and suffering. Lieut. Uaiidlnrkook,Co. II.. 70th Indiana Yols.
