I知 in the end stages of researching a book on the Confederate exodus to Mexico in 1865, with an emphasis on Shelby痴 Expedition. So far I have spent over 5 years researching as much material as possible, but I知 looking for anything I might have missed. I知 especially interested in obscure references, as well as unpublished manuscripts and primary source material, such as letters or reminiscences from post-war newspapers. I previously posted a message on the Missouri board and got some great responses. Texans also played a large role in the exodus, so any help would be greatly appreciated!
