Explanation: Sargon conquered Ur and E-Ninmar and "laid waste" the territory from Lagash to the sea, and from there went on to conquer and destroy Umma, and he collected tribute from Mari and Elam. He triumphed over 34 cities in total. Ships from Meluhha, Magan and Dilmun, rode at anchor in his capital of Akkad. Submitting himself to the (Levantine god) Dagan, Sargon conquered territories of Upper Mesopotamia and the Levant, including Mari, Yarmuti (Jarmuth?) and Ibla "up to the Cedar Forest (the Amanus) and up to the Silver Mountain (Aladagh?)", ruling from the "upper sea" (Mediterranean) to the "lower sea" (Persian Gulf). He entertained a court or standing army of 5,400 men who "ate bread daily before him".
