“June 6 – Promoted to Corporal. Left Florida and arrived at Fort Beny. Harrison Indiana on the 9th” He did not have time to write for so long because of his training. For those of you who do not know military ranks Corporal is an E – 4 rank, meaning it is the fourth highest rank(if you look at the ranks from an ascending order starting with the lowest which is private). Fort. Beny is short for Fort Benjamin Harrison, it was used during WWI and WWII for training purposes. It is currently a state park you can visit.
