United States Army Officer. Original burial site of Lt Reily, who was killed at the Battle of the Little Big Horn. His last name has also been spelled Reilly. But all school and military records spell his last name with one l. When Reily was only 9 months old, his father, William Reily, a naval officer, died. On September 24, 1854, his ship, the USS Porpoise, went down in a typhon off of the coast of Formosa. His mother remarried on July 11, 1861 to a Col L.M. Johnson. Reily attended Georgetown University, but left for an appointment to the United States Naval Academy, He attended the academy from 1870 to 1872, before being dismissed for deficiencies in math and the sciences. Reily returned to Georgetown. While at Georgetown, he traveled abroad to Dresden Germany. When Reily returned to the US in 1875, he accepted a commission as a 2nd Lt with the 10th US Cavalry Regiment. On January 26, 1876, Reily was transferred to Company E, 7th US Cavalry Regiment. Reily was described as a "dashing and handsome officer". He was also one of the most junior officers in the regiment. Legend has it that Reily had just barley learned to ride a horse, when the 7th Cavalry departed Ft Lincoln on the Yellowstone Expedition and the Battle of the Little Big Horn. His family estate was known to raise and breed horses. In addition, he had already served in another cavalry regiment. So it is very likely that Reily already knew how to ride. Reily was killed with Custer's command at the Battle of the Little Big Horn. His body was found near the crest of Last Stand Hill with several other officers. He was buried, where his body had been found. Two years after the battle, a Cheyenne warrior surrendered at Ft. Robinson. He was found to be in possession of Reily's ring. The ring was recovered and sent to his mother. In 1887, all known officer burials (except for Lt. Crittenden) were disinterred and returned to their families or buried elsewhere. Reily was reburied on August 3, 1877, at Mount Olive Cemetery, Lot 2 West, Section R37 in Washington DC.
