All of Alexander's men were practically dying with thirst, in the middle of the desert. Alexander’s men found a small trickle of water and poured it into a helmet and gave it to Alexander. Alexander Dumped the water into the ground in full view of every one of his soldiers.
Had not heard that--thanks.
Relatedly, have you seen the marvelous WW2 movie Sahara with Humphrey Bogart, where lack of water for soldiers in the desert plays such a central role?
