Only 12 of 36 company officers had yet been appointed, all by Department Commanding General William Rosecrans upon their arrival in Louisville, and only two-thirds of the non-commissioned officers had been named, so that widespread discontent with the lack of leadership spread through the regiment when it was sent on December 8 to Nashville, Tennessee. Making its march mounted and in inclement weather, when it reached Bowling Green, Kentucky, it was sent on an all-night march to Glasgow, Kentucky, where Confederate General John Hunt Morgan was reported camped with part of his regiment, but when the Anderson Cavalry charged into the town at dawn Morgan had left an hour before.
