Arrian

“ Those of the Thebans who had been drawn up opposite the temple of Amphion stood their ground for a short time; but when the Macedonians under the command of Alexander were seen to be pressing hard upon them in various directions, their cavalry rushed through the city and sallied forth into the plain, and their infantry fled for safety as each man found it possible. ”

“ Then indeed the Thebans, no longer defending themselves, were slain, not so much by the Macedonians as by the Phocians, Plataeans and other Boeotians, [4] who by indiscriminate slaughter vented their rage against them. Some were even attacked in the houses, having there turned to defend themselves from the enemy, and others were slain as they were supplicating the protection of the gods in the temples; not even the women and children being spared.
