EXCERPT:
On February 15, 1863, the 10th Missouri Cavalry joined with the Army of the Tennessee at Grant's forward command post at Corinth, Mississippi. Soon after arriving, a long-running feud erupted between the regimental lieutenant colonel, William D. Bowen, and the senior major, Thomas Hynes, resulting in the court-martial of the latter. Hynes never returned to duty with the 10th Missouri and Benteen became the senior major of the regiment.

Physician was born 8/3/1829, in Bridgeport, Ohio, son of an Irish immigrant who had settled there some years earlier. He was carefully educated, being graduated from St. Mary's Jesuit College, of Marion County, Kentucky, and completing his studies at New York University. After graduating from the last named institution in 1849, he crossed the plains to the Pacific Coast, and was the first physician to open an office, and begin the practice of medicine in Sacramento, California. In 1852 he returned to the states, and settled in St. Louis, where he was engaged in general practice until appointed physician of the City Hospital. After serving three years in that capacity, he resigned to become surgeon of the volunteers of the First Missouri Infantry Regiment, commanded at the beginning of the Civil War by Colonel--afterward General--Frank P. Blair. He was, up to the time that he entered the Union Army, Brigade Surgeon of the Missouri Militia on the staff of General D. M. Frost. In 1862, he resigned the surgeonship of the First Missouri Infantry to raise the Tenth Missouri Cavalry Regiment, of which he was commissioned colonel. He commanded this regiment with skill and ability, and had many engagements with General Forrest, and established an enviable reputation for bravery and gallantry as a commanding officer. He was killed in a personal difficulty by one of his officers, and his remains were afterward brought to St. Louis and buried in Cavalry Cemetery. A monument erected to his memory by admiring friends bears this inscription:
Colonel Florence M. Cornyn
Born 8/3/1829
Died 8/10/1863
"After life's fitful fever, he sleeps well."
"This monument was place here by his friends and comrades in arms" "to perpetuate the memory of a soldier without fear, and a patriot without reproach."
A list of the engagements in which he participated, inscribed on the monument, shows him to have taken part in the capture of Camp Jackson, and the battles at Booneville, Dug Springs, Wilson's Creek, Fort Donelson, Shiloh, Corinth, Tuscumbia, Lundy's Lane, Town Creek, Florence, Iuka, Burton and Leighton.
