Historical Background
The events are described in the epic poem "Gilgamesh and Agga". The king of the city of Kish, Agga sent ambassadors to the city of Uruk, demanding to participate in irrigation works. The Council of Elders of Uruk offered King Gilgamesh to obey and fulfill Agga's demand. But Gilgamesh refused to submit. The people's assembly proclaimed Gilgamesh a military leader - a lugal. Agga arrived with an army on rooks, traveling down the Euphrates. He laid siege to Uruk. The siege ended in the defeat of the army of Kish, and King Agga was captured. The victor treated the captives graciously and let Agga go free. According to one version, Gilgamesh benefited from having an ally against the powerful king of Ur, Mesanepad.
The scenario shows what a battle between the militia of Uruk and the army of Kish might have looked like.
