Steve: I believe you may have your Owensville's confused. Yes there was a skirmish at Owensville Missouri on March 31, 1863. However the 2nd Ohio was at Owensville KY on that date having just moved from Mt Sterling KY.

See below from Dyers

Ordered to Columbus, Ohio, December, 1862, and duty there till March, 1863. Moved to Somerset, Ky., and duty there till June 27. Mt. Sterling, Ky., March 19 (3rd Battalion). Owensville March 31. Expedition to Monticello and operations in Southeastern Kentucky April 26-May 12. Action at Monticello May 1. Near Mill Springs May 29. Monticello, Rocky Gap and Steubenville June 9.

Important to note the 2nd Ohio Cav was active early in the war on the Missouri - Kansas - IT border but had been sent back to Ohio for a re fit in December 1862. I'm not aware that any part of the unit was at Owensville Missouri March 31, 1863.
