Tweedale (Company B) and John Gregory Bourke (Company D, and just 16 years old), both of whom became officers in the regular army after the war, were later honored for gallantry at Stones River, two of the six troopers of the Anderson Cavalry who eventually received the Medal of Honor. In the week after it arrived in Nashville, total casualties of the 15th Pennsylvania Cavalry were 14 dead, 10 wounded, and 57 captured, many of whom had been wounded on December 29 and were in a hospital captured early on the first day of battle at Stones River. Subsequent campaigning 1863 reorganization Colonel Palmer was exchanged in January 1863 and resumed command of the now dismounted regiment on February 7. It moved it into a new camp at Murfreesboro, Camp Garesché, named for Rosecrans' chief of staff killed at Stones River, where Palmer assembled his command and promised it a complete reorganization by the end of the month. Nine of the 12 company officers originally appointed by Rosecrans resigned February 27 and were not re-appointed. The regiment was expanded to 12 companies with the old companies broken up and the men redistributed. Palmer chose permanent officers to fill all vacancies, the majority of whom came from the enlisted ranks of the Anderson Troop and had been serving as temporary officers since December 28. A new lieutenant colonel from outside the regiment, Charles B. Lamborn, arrived on March 7 to replace Spencer, who resigned in poor health on February 6. A few days later new equipment was issued and 200 horses received. Mounted drill resumed and by April the regiment was again conducting scouting operations for the Army of the Cumberland east of Murfreesboro. The remaining 212 confined men were returned to duty with charges against them suspended on condition of good behavior henceforth. A final organizational crisis occurred on May 8, 1863, when 13 officers appointed on March 1 resigned as a group because their commissions from Pennsylvania Governor A. G. Curtin had not yet been acted upon. Palmer accepted the resignations and promoted replacements from the ranks of the regiment. Department of the Cumberland For the remainder of the war, the 15th Pennsylvania remained in the Department of the Cumberland, with Companies B, H, and K tasked as escort for department headquarters. The remaining nine companies scouted, conducted periodic raids, and frequently engaged in skirmishes under Palmer. The regiment
