LOL, it seems you have a little hero worship there, actually I would consider this North Vietnamese Colonel and journalist’s take on the situation, over what ever Giap may have tried to sell for the future of communist history, years after the war, especially since the Colonel’s take matches what is believed to be the truth of the situation.
The man that you sneeringly call a “defector” left Vietnam in 1990, not exactly in the heat of battle.
It seems that you have a lot more interest in this than correcting a quote, it seems that you have a side in the war, and no, Giap is not credible on anything.
