For the space of three days the Lombards strove so valiantly that they slew a very great company of Charles's men. But on the third day Charles set in order the hardiest and bravest of his host and said to them--
"Go now, and win this battle, or return no more."
So King Didier together with the host of the Lombards fled to the place called Mortara, which was then known as Belle-Forêt, because the country was so fair, there to refresh themselves and their horses. On the morning of the next day King Charles with his army drew near the town, and found the Lombards arrayed for the battle. So fierce was the combat that a great multitude of men were slain, both of one party and the other, and for reason of this slaying was the place named Mortara. There, too, on that field died Amis and Amile, for as it had pleased God to make their lives lovely and pleasant together, so in their deaths they were not divided. There also many another hardy knight was slain with the sword. But Didier, together with his Justiciary, and all the multitude of the Lombards, fled to Pavia; and King Charles followed closely after him and lay before the city, and invested it on every side; and lying there he sent to France to seek the Queen and his children. But St. Albin, the Bishop of Angers, and many another bishop and abbot counselled the King and Queen that they should bury those who fell in that battle, and build in that place a church. This counsel greatly pleased the King, so that on the field were built two churches, one by bidding of Charles in honour of St. Eusebius of Verceil, and the other by bidding of the Queen in honour of St. Peter.
Moreover the King caused to be brought the two coffins of stone wherein were buried Amis and Amile, and Amile was carried to the church of St. Peter, and Amis to the church of St. Eusebius. But on the morrow the body of Amile in his coffin of stone was found in the church of St. Eusebius near by the coffin of his comrade, Amis. So have you heard the story of this marvellous fellowship which could not be dissevered, even by death. This miracle did God for His servants--that God Who gave such power to His disciples that in His strength they might move even mountains. Because of this wonder the King and Queen tarried there for thirty days, giving fit burial to the bodies of the slain, and honouring those ministers with many rich gifts.
