Well you piqued my curiosity. I’d forgotten what they all mean, or how many there are.
I found a pretty good website (Lawforveterans.org) that lays out the different discharges, a DD is usually or often recieved in conjunction with serving time in a prison. Maybe Leavenworth would be of some assistance in this matter. Here are some of the possibilities, to achieve a Dishonorable Discharge:
Murder
Fraud
Desertion
Treason
Espionage
Rape
We're Irish, and my father had that Irish temper when we kids were growing up, but when he became a grandpa, then a great grandpa, wow did he become a big softy.
But back then, if he was somehow traumatized by something that happened on the battlefield, well, I dunno, but who knows, maybe he snapped. I just find it odd that his first DD214, which was for five years, was honorable, but the second one, which was for 28 months, was dishonorable. It doesn't make sense.
I sent a request to the NPRC for a copy of his military records. Guess we'll see if they shed any light on it.
Thanks for your help, and your kind words.
