Thank you George for the response. First I would like to apologize for not posting on the Tn site...I meant too but was half asleep.
So Isom never returned after Vicksburg? Would he have been allowed to live at the confederate home and be buried in the Cemetery,if he had had not eventually gotten his pension? Here is what I found on him from the Hermatige Confederate Soldiers home.

SHEETS Born: 1831 Died: 1922

Front inscription: ISOM SHEETS/ 43 TENN. INF./ 1831 - 1922

Site and gravestone #: 314-393*

The 43rd had an illustrious career, I just hope that Isom served with them untill the end.

Thanks for any and all info
