Interesting. I was aware of Operation Vulture but not discussion of using three atom bombs to relieve the French surrounded at Dien Bien Phu.
But I read your Wikipedia reference a little differently. Eisenhower did not want American pilots to drop the bombs. Churchill wanted nothing to do with the intervention requested by Eisenhower. Basically, without Britain and Congressional consent Eisenhower would not sign off on Operation Vulture.
An article published in the
Bulletin of the Atomic Scientists, discusses both Operation Vulture planning and Dulles offer to Bidault. The Americans were gung ho. The French not so much.
According to Bidault, the American took him aside during an intermission and asked him whether atomic bombs could be effective at Dien Bien Phu. If so, Dulles allegedly went on, his government could provide two such bombs to France. Bidault said he turned down the suggestion flat, on the grounds that the bombs would destroy the garrison as well as the Viet Minh, while dropping them farther away, on supply lines, would risk war with China. When informed a few months later of Bidault’s claim, Dulles said he could not recall making such an offer and insisted there must have been a misunderstanding.
Bidault’s version is supported by senior French official Jean Chauvel in his memoirs, and by French general Paul Ely in his diary, which was kept on a daily basis. Ely, a key player on Indochina strategy in these months, wrote that he was of two minds about “the offer of two atom bombs. The psychological impact would be tremendous, but the [military] effectiveness would was uncertain, and it carries the risk of generalized warfare.” --
“We might give them a few.” Did the US offer to drop atom bombs at Dien Bien Phu? Fredrik Logevall, Bulletin of the Atomic Scientists, February 21, 2016
What's the truth? As with most controversies probably somewhere between. Good article. Read it if you have the chance.
