Thomas Henderson of Henderson's Scouts was shot twice by accident. The first time was just before Shiloh when his gun got caught up in brush/limbs as he was riding. Took off his ankle and he was crippled throughout the war. So now we have four men hanging out after Shiloh and one says I missed the battle because I had the trots, another says I missed the battle because I was stepped on by a mule, the third says I missed the battle because I shot myself by accident, and finally the fourth says none of those happened to me and I had to go into battle.... No wonder there are arguments today about the number of men who actually took the field in any given battle and why it is almost impossible to say if any particular person actually fought in a given battle.
