When I was going through Quantico in 68, the SNCOs were still having nightmares about the decade prior episode where where some DIs marched a platoon through the swamp and several died of exposure.
When I played ball in HS and college..coaches wouldn't allow us to drink during practice....it was a mark of weakness. Bear Bryant was famous for that. It's amazing that half of the SEC football teams of the 50's didn't drop dead during summer camp.
Your talking about The Ribbon Creek incident.
