 According to Xenophon's "Cyropaedia" (4.6.1-11), Gobryas, governor of Gutium under the suzerainty of the Babylonians, had a long-standing grudge against the Babylonian king.After Cyrus defeated Croesus, Gobryas came to Cyrus and indicated his allegiance.Gobryas figures prominently in events that follow, giving his advice about how to proceed in the capture of Babylon, and then leading the forces that took the city (5.4.41-50; 7.5.8-33).
