Louis Jeanottelle Sacriste (June 15, 1843 – August 18, 1904) was a first lieutenant (also brevet major) in the United States Army who was awarded the Medal of Honor for gallantry during the American Civil War.

[1][2] Sacriste later described these actions in writing:[3] I was a second lieutenant commanding Co. D, One hundred and sixteenth Pennsylvania Volunteers, Meagher's Irish Brigade, Hancock's First Division, Second Corps.

At Chancellorsville, Saturday night, May 2nd, 1863, our brigade deployed near Scotts Mills and when General 'Stonewall' Jackson charged the Eleventh Corps under Howard, we had orders to prevent a possible stampede, but met with little success.

As we were forming, the Fifth Maine Battery under Captain Le Peine took up position between our left and the Chancellor House and opened fire at once with excellent effect, which, however, was only temporary.

Men and horses of our battery were mowed down with such rapidity, that in less than an hour every gun, with one exception, was silenced, and but two noble fellows, Corporal Charles Lebrooke and Private John F. Chase, remained at their posts.

A few minutes later the enemy had possession of the field.Second action: On the night of the 13th of October, 1863, during a retrograde movement of the army, I was ordered, with twenty-five picked men from my regiment (One hundred and sixteenth Pennsylvania Volunteers) to report to Colonel James A. Beaver, commanding the picket line of the First Division, Second Corps.

Colonel Beaver, seeing the critical position and danger of capture or destruction of his entire command, and perceiving but one avenue of escape, requested me to proceed along the line, which was heavily engaged and stubbornly contesting the ground, inform the officers of the situation, and direct them as to the route of march, which was to fall back slowly on the same side of the creek with the enemy, cross the stream south of the ford, and then march diagonally across the country to rejoin the division.

Considering all the circumstances, the escape of the line was remarkable, and our action and stubborn courage made us the ideal of a rear guard.Sacriste was mustered out of service on March 6, 1865, in Alexandria, Virginia, and was awarded the Medal of Honor, accredited to Nebraska, on January 31, 1889.
