September 17, 1864 - battle on the Atchafalaya River
September 20, 1864 - battle at Bayou Ala and Morgan's Ferry

I know this is pretty vague, but I am in hopes these battles are familiar to someone and they can tell me the locations of these battle sites. I cannot find anything that tells the exact locations. These battles involved Terrell's TX Cavalry which I am researching.

Thanks for any help.
