Bede. 679. In the aforesaid battle, wherein Elfwin, the king's (age 34) brother, was killed, a memorable fact is known to have happened, which I think ought not to be passed by in silence; for the relation of the same will conduce to the salvation of many. In that battle, one Imma, a youth belonging to the king, was left as dead, and having lain so all that day and the next night among the dead bodies, at length he came to himself, and sitting, bound up his wounds in the best way he could. Then having rested awhile, he stood up, and began to go off to seek some friends that might take care of him; but in so doing he was discovered and taken by some of the enemy's army, and carried before their lord, who was an earl belonging to King Ethelred. Being asked by him who he was, and fearing to own himself a soldier, he answered, "He was a peasant, poor and married, and that he came to the army with others to bring provisions to the soldiers." The earl entertained him, and ordered his wounds to be dressed; and when he began to recover, to prevent his escaping, he ordered him to be bound; but that could not he performed, for as soon as they that bound him were gone, his bonds were all loosened.

Battle of the Trent

Anglo-Saxon Chronicle. 679. This year Elwin was slain, by the river Trent, on the spot where [his half-brother] Everth (age 34) and Ethelred fought. This year also died St. Etheldritha (age 43); and the monastery of Coldingiham was destroyed by fire from heaven.

Around 679 King Æthelred of Mercia defeated the Northumbrian army led by [his half-brother] King Ecgfrith of Northumbria (age 34) at the Battle of the Trent somehere in Lindsey [Map]. King Aelfwine of Deira was killed.


In the ninth year of the reign of [his half-brother] King Egfrid, a great battle was fought between him and Ethelred, king of the Mercians, near the river Trent, and Elfwin, brother to King Egfrid, was slain, a youth about eighteen years of age, and much beloved by both provinces, for King Ethelred had married his sister [his half-sister] Osthrid. There was now reason to expect a more bloody war, and more lasting enmity between those kings and their fierce nations; but Theodore, the bishop beloved of God, relying on the Divine assistance, by his wholesome admonitions extinguished the dangerous fire that was breaking out; so that the kings and their people on both sides being appeased, no man was put to death, but only the usual mulct paid to the king for his brother that had been killed; and this peace continued long after between those kings and their kingdoms.
