Attila had already arrived before Orleans, and was laying siege to it. The bishop, St. Anianus, sustained awhile the courage of the besieged by promising them aid from Aetius and his allies. The aid was slow to come; and the bishop sent to Aetius a message: "If thou be not here this very day, my son, it will be too late." Still Aetius came not. The people of Orleans determined to surrender; the gates flew open; the Huns entered; the plundering began without much disorder; "wagons were stationed to receive the booty as it was taken from the houses, and the captives, arranged in groups, were divided by lot between the victorious chieftains." Suddenly a shout reechoed through the streets: it was Aetius, Theodoric, and Torismund, his son, who were coming with the eagles of the Roman legions and with the banners of the Visigoths. A fight took place between them and the Huns, at first on the banks of the Loire, and then in the streets of the city. The people of Orleans joined their liberators; the danger was great for the Huns, and Attila ordered a retreat. It was the 14th of June, 451, and that day was for a long while celebrated in the church of Orleans as the date of a signal deliverance. The Huns retired toward Champagne, which they had already crossed at their coming into Gaul; and when they were before Troyes, the bishop, St. Lupus, repaired to Attila's camp, and besought him to spare a defenceless city, which had neither walls nor garrison. "So be it," answered Attila; "but thou shalt come with me and see the Rhine; I promise then to send thee back again." With mingled prudence and superstition the barbarian meant to keep the holy man as a hostage. The Huns arrived at the plains hard by Chalons-sur-Marne; Aetius and all his allies had followed them; and Attila, perceiving that a battle was inevitable, halted in a position for delivering it. The Gothic historian Jornandes says that he consulted his priests, who answered that the Huns would be beaten, but that _the general of the enemy_ would fall in the fight. In this prophecy Attila saw predicted the death of Aetius, his most formidable enemy; and the struggle commenced. There is no precise information about the date; but "it was," says Jornandes, "a battle which for atrocity, multitude, horror, and stubbornness has not the like in the records of antiquity."
