Benjamin Littleton Wynn (November 3, 1839 - July 25, 1917) was a Confederate soldier during the American Civil War. He was in Company A of the Twenty-First Regiment of Mississippi, and later, was on signal duty for the Army of Northern Virginia at the outset of the Battle of the Wilderness in 1864. He kept a diary during this latter duty, which survives to this day. After the war, Wynn practiced law and served in the Mississippi state legislature, occasionally writing articles for Civil War educational journals.
Sergeant B.L. Wynn was in charge of a Confederate signals station atop of Clark's Mountain during the winter of 1863-4. General Robert E. Lee was frequent visitor since the summit had an excellent view of the encampments of Army of the Potomac which allowed the general to study their formations and activities. On May 2, 1864 Wynn casually came out of the signals hut to greet Lee and was surprised to find most of the top ranking officers of the Army there too for a conference.
