The story of Lt. Wilson is somewhat unclear. A letter from Captain Ed J. Wood from camp near Corinth, MS, April, 1862:
Inventory of the effects of Z. W. Wilson, 2nd lieutenant of Captain E. J. Wood’s Company missing since the Battle of Shiloh on 7th of April, 1862. Due him for 26 days service at $17 per month, $14.75. Due him for 2 months __days as 2nd lieutenant at $80 per month
$192.40. Total amount due $207.15. The above statement is correct to the best of my knowledge.
Signed: Captain Ed J. Wood
However, it is possible that Wilson died as a POW at Camp Chase on May 21st, 1862 as a prisoner of war after being captured at Shiloh. One way or another, whether he was killed outright on April 7th, or died later, possibly wounded, as a POW, Lt. Wilson ultimately died as a result of the Battle of Shiloh.
