Two Ashley brothers, W.A.(Walter Alexander) and H.C. (Henry) C. Ashley served in Dobbins 1st Ark. Cav.

Henry was taken prisoner and paroled at Wittsburg, Ark. May 25, 1865. Can anyone tell me what precipitated Henry's capture and the circumstances of his parole.

Would also like to know what battles these 2 brothers fought in, and maybe just some general info abt. Dobbins 1st Ark. Cav.
Thank You,
Mary
