And now Seleucus, who had once been expelled from Babylonia by Antigonus, but had afterwards succeeded in recovering the realm and was now wielding the power there, went up with an army, designing to annex the tribes on the confines of India and the provinces about Mount Caucasus. Demetrius, accordingly, expecting that he would find Mesopotamia unprotected, suddenly crossed the Euphrates and invaded Babylonia before Seleucus could stop him. He expelled from one of its citadels (there were two of them) the garrison left there by Seleucus, got it into his power and established in it seven thousand of his own men.
