The Macedonians swept down the waving grain with their pikes, to open a way for the advance of the cavalry, and early in the morning Alexander found and attacked the army of his enemies, who were utterly astonished at finding him on their side of the river. As may be easily anticipated, the barbarian army was beaten in the battle that ensued. Their city was taken. The booty was taken back across the Danube to be distributed among the soldiers of the army. The neighboring nations and tribes were overawed and subdued by this exhibition of Alexander's courage and energy. He made satisfactory treaties with them all; took hostages, where necessary, to secure the observance of the treaties, and then recrossed the Danube and set out on his return to Macedon.
