Alexander the Great: The fall of Tyre
"The extent of the bloodshed can be judged from the fact that 6,000 fighting-men were slaughtered within the city's fortifications. It was a sad spectacle that the furious king {Alexander} then provided for the victors: 2,000 Tyrians, who had survived the rage of the tiring Macedonians, now hung nailed to crosses all along the huge expanse of the beach.
Alexander was a constitutional monarch who had to be proclaimed in office according to the Macedonian constitution. Thus he was not a tyrant-see my post#11.
