The History Place. Vietnam war

[Charles Martel]

Nice link there on Vietnam. My father-in-law once told me, in a rare example of willingness to discuss his military service, a bit about the "seeds of the conflict" as noted at the link - particularly the October 1945 time frame.

He was a navigator aboard a USN patrol bomber - a big flying boat (Martin Mariner / PBM). The squadron was activated late in the war and most of the men had low rotation points by VJ Day, so instead of being mustered-out, they were sent into China to help preserve the truce between the Nationalists and the Communists. There were Marines sent into China as well... don't know about Army.

That effort apparently didn't last long, but one of the things that squadron did while there was send a plane into Vietnam to rescue a French diplomat, right around the end of the year.
