I am not aware of a possible skirmish but, in general that would of been during the Tullahoma Campaign.Which some might say started upon Braggs retreat to Shelbyville-Duck River after the battle of Murfreesboro Dec.31-Jan.5,1863.Both armies took winter camp and the campaign started in ernest early June of 1863.Confederate forces were scattered between Wartrace and Shelbyville.Look up Tullahoma Campaign for more information.
