If you have not read the first half, look here.
Below are two images from reenactments of the battle. I doubt they recreate the massacre for family audiences.
Final Push
On
the Union left Companies C and I, 1st Kansas Colored, saw about a
hundred men in blue coats pass along their front. They assumed they were from
the 2nd Kansas Cavalry as well as sharpshooters from the 18th
Iowa. They were soon corrected when hundreds of Confederate cavalry appeared
alongside them Cabell had ordered Crawford, who to this point had only
skirmished, to move all of his available men forward. Gibbons “immediately
ordered the men to fire, which was kept up for a few minutes only, but with
such effect as to check the enemy’s advance.” Among the men commended in
Gibbons’ report was First Sergeant Berry, a black officer who urged his men to
think of freedom and hold their place.[1]
Gibbons ordered his men 60 yards back. They fired a volley, but made another withdrawal when they saw the rest of the regiment in retreat. Crawford’s Confederates “moved rapidly and steadily forward, firing volley upon volley” at the black troops. Gibbons attempted to mount his horse. He tripped on his saber halfway up and the horse “became scared and dragged me about 5 yards.” His infantry left him behind and he was left alone against the on-rush of screaming Rebels. “I need not say I mounted quick and rode away quicker.”[2]
