There is some difficulty in determining the exact date of this celebrated engagement. Sharon-Turner gives it as 934. Worsaae in his "Danes and Norwegians in England," says 937. Ethelwerd's Chronicle says 939. Sharon-Turner refers to the fact that one MS. of the Anglo-Saxon Chronicle gives the date 937, notwithstanding which he prefers 934. Dr. Freeman in his "Old English History" adheres to 937, which seems to be the most probable date. We find that British Christians, as on previous occasions, espoused the cause of the heathen Danes, rather than fraternize with their hated Anglo-Saxon rivals, the disciples of Augustine and Paulinus. Thus many elements combined to render this battle one of the bloodiest and most destructive ever fought on British soil. The great struggle did not take place immediately on the arrival of Anlaf and his allies. Athelstan's two governors, Gudrekir and Alfgeirr first confronted the invaders. The former was slain and the latter fled to his sovereign, with the news of their discomfiture. Athelstan, with wise forethought, tried the effect of diplomacy, if only for the purpose of gaining sufficient time for the assembling of all his forces before staking his sovereignty upon the issue of a single battle. The authorities, contemporary or nearly so, for the details of this decisive campaign, although meagre in comparison with those of more recent struggles, are nevertheless fuller than usual for the period. We have the poem in the Anglo-Saxon Chronicle, a notice in Ethelwerd's Chronicle, and some Scandinavian accounts, notably Egil's Saga. Sharon-Turner, however, regards the northern authorities as not entitled to implicit reliance, as their great object was the laudation of Egil and Thorolf, Scandinavian mercenaries in the pay of Athelstan, who, they contend, mainly contributed to the victory by the annihilation of the "disorderly Irish" contingent.
