A couple weeks ago I was at the US Naval Academy at Anapolis. While there, I learned about John W. Ripley, USMC Ret.
My host at the Academy spoke about Col. Ripley, who lived nearby and came to Mass there.
Now I understand from the site of talk radio host Hugh Hewitt that Col. Ripley died recently.
Here is the diorama at the Academy of what Col. Ripely did.
During the Easter Offensive of 1972, he dangled for three hours under a bridge near the South Vietnamese city of Dong Ha in order to attach 500 pounds of explosives to the span, ultimately destroying it. His action, under fire while going back and forth for materials, is thought to have thwarted an onslaught by 20,000 enemy troops.
