You left off the 3rd Ark Cav, dismounted. Was the 2nd really there or was that supposed to be the 3rd you think?? My relative lies in that grave no doubt as he was captured from Corinth battlefield, and died one month later at Iuka per his CSR. 3rd Ark Cav were in vicinity of Battery Robinette and I believe brigaded with some of the Texans but cant remember for sure without looking it up. Quite a few bit the dirt there and the wounded were taken to Iuka by the Feds with quite a few dying there no doubt. Just another thought you might want to include.
