Well, eventually, Alexander catches up with Bessus in 329. He's really angry that Bessus has killed Darius. He's also likely angry that Bessus is claiming that he is the Shah-in-Shah. And so he kills Bessus in fairly brutal form. And there's different accounts of how the killing happened, but all of them are various degrees of brutal. But from there, Alexander's troops continued on eastward, continued on eastward into what we now consider to be Afghanistan and Pakistan. And there he has the famous battle with the king of Porus, where he encounters these 200 war elephants.
