I keep running into this story and I was wondering if this had any truth to it I would also like to see any evidence that proves this is fact.

The story goes that during the battle of Fredricksburg in December 1862 Sgt. Richard Kirkland of the 2nd South Carolina climbed over the stone wall and took canteens of water to wounded federals on the other side while under fire.

Sgt. Kirkland was killed in the battle of Chickamuaga in 1863 from what I can gather.
