In one reconstructed account,[citation needed] a battle was fought at Opis in the month of June, where the Babylonians were defeated; and immediately afterwards Sippar surrendered to the invader. Nabonidus fled to Babylon, where he was pursued by Gobryas, and on the 16th day of Tammuz, two days after the capture of Sippar, "the soldiers of Cyrus entered Babylon without fighting." Nabonidus was dragged from his hiding place, where the services continued without interruption.
