Gail,
I would like very much to get a copy of the letter for the Fort DeRussy Library. If you would send it to Friends of Fort DeRussy, 7162 Hwy 29, Cottonport, LA 71327, we would be happy to reimburse you for copying and postage. Thanks.
Would you know if your great-grandfather was on the Webb in 1863, when it attacked USS Indianola?
