I found something in the OR's that helps explain the relationship of Poe's Cav BN, 11th Ark Cav, and Logan's Arkansas Cavalry...In the actions around Princeton just prior to the battle at Hurricane Creek, a report was made that states "Major Poe, commanding a portion of the 11th Ark Cavalry,"... so my analysis seems to be correct. Poe raised his battalion late in 1863. When Logan came over, he and Poe evidently linked up with men they had enlisted as well as men from the 11th and 17th who remained west of the Miss R. and joined up with their former officers they had served under previously. And in a nutshell they are all the same and exact unit...Poe's/Logan's/11th Ark Cavalry.
