I have a cousin who did that. Hey Al, thanks for the memories.
It should be noted that the Viet Minh shelled the french with US 105 mm artillery shells and guns captured from the 1st Cav in Korea. They still had the bumber numbers on them.
Morale: Destroy your guns before you bug out!
There is also a story that Charles Degaulle wanted the US to drop nuclear bombs, thereby writing a new page of glory for the Foreign Legion. Ike refused. DeGaulle used that as his excuse to pull French Military out of NATO.
I don't think the timeline is right, but it is an old rumble.
During the Korean War, the 1st Cavalry Division suffered 16,498 casualties, in 18 months of continuous fighting. Some units were completely wiped out by the Communist Chinese.
