After Ross departed to meet with President Lincoln in Washington, traditionalist Cherokee helped maneuver the selection of Ross supporter Thomas Pegg as Acting Principal Chief. Three or four of Ross's own sons fought for the Union. However, Ross's nephew by marriage, John Drew, had organized and served as Colonel of the 1st Cherokee Mounted Rifles in the Confederate Army. Most of Drew's regiment would later twice desert rather than follow Confederate orders to kill other Indians. Many leaders of the northern faction, still led by Ross, went to Fort Leavenworth, Kansas for the duration of the war.
