Thanks so much! It appears that they were in prison together, and all three did survive the war. William even made a fortune when Aurora Springs was "discovered" as a health spa in the 1880's. Very interesting to tie all the pieces together.
I haven't been able to find out when John enlisted, but here's my guess as to what happened. All comments are welcome. Crabtree convinced the youngest brother, James, who would have been about 17, to go with him to Thomasville on his run in August 1862. William found out and followed, enlisting in his little brother's unit at West Plains a couple of weeks later. Either John came with James (Jim) or with William (Billy) and also enlisted in this unit.
Jim got seriously ill in Arkansas and his mother traveled from Mary's Home to Arkansas to care for him. During the time she was gone, there was an event at the home with their three younger siblings when soldiers came searching for guns, said to be 100 camped out in the yard. At some point Jim re-joined his unit and continued with his brothers until they were all taken prisoner. I'm still trying to research the history of Pindall's Sharpshooters to figure out when that happened. They were all released at the same time and their history after the war is a matter of record. I don't have any background researching Confederate units - only Missouri State Guard - so I don't really have a guess where to look for more information.
