I am presently doing extensive research on the Confederate artillery used at Poison Spring and later Guesses Creek. I know Capt. Samuel S. Harris Mo. battery was at both engagements. Specifically, I need to know if any of our readers may have any information detailing the types of cannon Harris' battery used during these engagements. I know from field work that Confederate 3 inch rifled shells have been excavated at Poison Spring. Aside from both 6 and 12 pounder Smoothbores I have read that there may have been Prairie Rifles used but very little is known about them. Any information would be greatly appreciated.
