"Jack Amos and other Choctaw Indians demonstrated much bravery during a train wreck that occurred on the Little Chunky Creek between Chunky and Hickory, Mississippi on February 19, 1863. A troop train bound for Vicksburg, Mississippi derailed at the last bridge three miles east of Hickory. Heavy rains had washed out the railroad bridge and the engineer failed to heed warnings that the bridge was out. It was reported by a Jackson, Mississippi newspaper “The Daily Southern Crisis” on February 26, 1863 that 60-plus solders and civilians died in the accident and were buried on the railroad right-of-way. Jack Amos, with other Indians, stripped and plunged into the water to save upwards of twenty-two people involved in the accident. Spann’s Battalion had been stationed in a nearby training camp when the accident occurred, and as reported by Spann, his troops were on the scene of the accident shortly after the wreck happened."
