And so they eventually meet again at Gagamella. Once again, a very significant battle in history where once again, Darius is there and has a significant force advantage over Alexander. And this time, doesn't make the mistake of meeting him in a relatively narrow area where his force advantage won't really be an advantage, but even at Gagamella, Alexander is able to decisively defeat him. And Darius has to flee over the mountains to Ekbatana. My apologies, because I know I'm probably not pronouncing it perfectly. And Alexander and his forces then go on to capture Babylon and Susa. And Susa was actually one of the capitals of the Achaemenid Empire.
