Jules Garesche "Gary" Ord (September 9, 1866 – July 1, 1898) was a United States Army First Lieutenant who was killed in action after leading the charge of Buffalo Soldiers of the 10th U.S. Cavalry up San Juan Hill. History now records that Ord was responsible for the "spontaneous" charge that took the San Juan Heights during the Spanish–American War in Cuba on July 1, 1898.
