What also made Isis significant is this is where, this is the first time that Darius III, the Shah-in-Shah, the king of Persia, directly confronts Alexander. Well, Alexander once again is able to, or at least here, is able to overcome unlikely odds and defeat the Persian army, sending Darius into retreat. And he retreats so fast, he even leaves an encampment where his mother, his wife, and his two daughters are there. And Alexander then takes them captive, but treats them very nicely, and then eventually marries one of the daughters. So after that defeat, Darius is on the retreat, and Alexander, or after that defeat for Darius, this victory for Alexander, Alexander then goes on into the Levant, modern-day Syria and Lebanon and Israel and Palestine. And you can see he takes siege of the cities of Tyre in Gaza but by the time he gets through that, it's now 332 and he makes his way into Egypt, and he's relatively unopposed. This traps in Egypt to say, okay, you know what?
