Although little is mentioned in his military records, Richwood was wounded at Shiloh, though the nature and severity of his wounding is unknown. The only indication that he was wounded is the fact that it was noted in his military records because of loss of equipment. It was noted that he lost a cartridge box and bayonet, but the note was made in under "remarks", he lost them because he was wounded and unable to carry them. The 1st Florida Infantry Battalion served in Gen. Patton Anderson's brigade alongside the 17th Louisiana Infantry, the 20th Louisiana Infantry, the Confederate Guards Response Battalion and the 9th Texas Infantry, along with the famed 5th Company of the Washington Artillery of New Orleans. The brigade was involved in fighting at Rhea Field and near Shiloh Church, and later at the Hornet's Nest. They made it as far as Dill Branch. Richwood was appointed 1st Sergeant on 1 April 1862, just 5 days before the Battle of Shiloh.
