Bruce: I really do not have any additional info on either Crabtree, L. P. or L. C. I can say that neither name appears in the list of Missouri Confederate soldiers on file at the National Archives. Thus, the possibility that he, or they, did not serve further, or that he/they became guerrillas.
The Company K recruited by L. C. Crabtree became part of the 10th MO Inf Regt, Confederate.
