Joshua Chamberlain did not receive his MOH until 1883. Thirty years after his action on Little Round Top.
Battlefield promotion to Brig.General, by Grant, and at Appamattox, selected to receive the surrendering infantry, and did so with great dignity and honor. His wounds eventually caught up with him at 85, having volunteered for the Spanish American War at 70, and been rejected. Tough individual, mentally and all else.
