Now, you know full well I was going for effect....
:^) My all-time favorite's probably the Nasser fiasco in 1967 -- Israel's one move was to wipe out the adversarial airforces on the ground, then punch through the skin -- Egypt's entire force was staging along the border with Israel, and Nasser had already ejected the UN's observers from the Sinai. I recall reading that Egypt's main losses came from troops fleeing on foot across the Sinai and dying of thirst. Nasser was listening to the Egyptian propaganda broadcast, but when the survivors were starting to swim the Canal and would be in Cairo in short order, someone had to draw the short straw and tell Nasser what had really been happening.
