David Hume - The History of England, Vol.I. Part A. ( Chap 3.2) lyrics

Edmond Ironside This prince, who received the name of Ironside from his hardy valor, possessed courage and abilities sufficient to have prevented his country from sinking into those calamities, but not to raise it from that abyss of misery into which it had already fallen. Among the other misfortunes of the English, treachery and disaffection had crept in among the nobility and prelates; and Edmond found no better expedient for stopping the further progress of these fatal evils, than to lead his army instantly into the field, and to employ them against the common enemy. After meeting with some success at Gillingnam, he prepared himself to decide, in one general engagement, the fate of his crown: and at Scoerston, in the county of Glocester, he offered battle to the enemy, who were commanded by Canute and Edric. Fortune, in the beginning of the day, declared for him; but Edric, having cut off the head of one Osmer, whose countenance resembled that of Edmond fixed it on a spear, carried it through the ranks in triumph, and called aloud to the English, that it was time to fly; for, behold! the head of their sovereign. And though Edmond, observing the consternation of the troops, took off his helmet, and showed himself to them, the utmost he could gain by his activity and valor was to leave the victory undecided. Edric now took a surer method to ruin him, by pretending to desert to him; and as Edmond was well acquainted with his power, and probably knew no other of the chief nobility in whom he could repose more confidence, he was obliged, notwithstanding the repeated perfidy of the man, to give him a considerable command in the army. A battle soon after ensued at Assington, in Ess**; where Edric, flying in the beginning of the day, occasioned the total defeat of the English, followed by a great slaughter of the nobility. The indefatigable Edmond, however, had still resources. Assembling a new army at Glocester, he was again in condition to dispute the field; when the Danish and English nobility, equally hara**ed with those convulsions obliged their kings to come to a compromise, and to divide the kingdom between them by treaty. Canute reserved to himself the northern division, consisting of Mercia, East Anglia, and Northumberland, which he had entirely subdued. The southern parts were left to Edmond. The prince survived the treaty about a month. He was murdered at Oxford by two of his chamberlains, accomplices of Edric, who thereby made way for the succession of Canute the Dane to the crown of England.
