December 31 those in camp were ordered to perform wagon train escort duty but again refused. 415 soldiers were arrested and confined for insubordination. They submitted a list of grievances as cause, alleging a failure to appoint a sufficient number of company officers (which was true; seven companies had no captain and four had no officers at all), being improperly mustered into federal service (or not at all), inadequate equipment and weapons, and enlistment inducements they claimed had not been honored. On January 19, 1863, Rosecrans offered to release from confinement those immediately willing to be restored to duty. 208 confined in the city workhouse still refused, but the others were returned to the ranks. Those returning to duty did so with recalcitrance and four were returned to confinement when they refused to perform picket duty. Battle of Stones River The 300 troopers who had marched with the army scouted the advance of the Union right wing, determining that the Confederate army was concentrating on Murfreesboro. It twice encountered Confederate forces, skirmishing with dismounted Texas cavalry units at Nolensville on December 27. In the second engagement, on December 29 at Wilkinson's Cross Roads west of Murfreesboro, its skirmishers were ambushed by Confederate pickets of the 10th South Carolina Infantry, leading to an impetuous mounted charge with carbines by the battalion under Rosengarten. However two regiments of Confederates concealed in a corn field were drawn up in line of battle behind a fence paralleling the pike. Stopped by the fence and receiving aimed volleys of musket fire at point-blank range, the regiment quickly lost 11 men killed, 50 wounded and 9 missing. Rosengarten was killed and Major Frank B. Ward, another former sergeant in the Anderson Troop, was mortally wounded, dying on January 11, 1863. Ward was barely 20 at the time he was wounded. Under the command of a captain, the survivors of the regiment deployed with Stanley's cavalry on the right of the Union position, taking part without loss in two mounted saber charges late on the first day of the Battle of Stones River that drove a brigade of Confederate cavalry from the field, with troopers of the Anderson Cavalry capturing the colors of the 3rd Alabama Cavalry. On New Year's Day it escorted the army's supply wagons back to Nashville, repulsing several attempts by the Confederate cavalry of Gen. Joseph Wheeler to destroy the train. Privates John
