to be Oswald's undoing. He was killed in 642, by the Mercians at the Battle of Maserfield, in Oswestry (although other candidates for the location of the battle have been suggested) and his body was dismembered. Bede mentions the story that Oswald "ended his life in prayer": he prayed for the souls of his soldiers when he saw that he was about to die. Oswald's head and limbs were placed on stakes. The traditional identification of the battle site with Oswestry, probably in the territory of Powys at the time, suggests that Penda may have had British allies in this battle, and this is also suggested by surviving Welsh poetry which has been thought to indicate the participation of the men of Powys in the battle. It has also been considered that, if the traditional identification of the site as Oswestry is correct, Oswald was on the offensive, in the territory of his enemies. This could conflict with Bede's saintly portrayal of Oswald, since an aggressive war could hardly qualify as a just war, perhaps explaining why Bede is silent on the cause of the war—he says only that Oswald died "fighting for his fatherland"—as well as his failure to mention other offensive warfare Oswald is presumed to have engaged in between Heavenfield and Maserfield. Oswald may have had an ally in Penda's brother Eowa, who was also killed in the battle, according to the Historia Britonnum and Annales Cambriae; while the source only mentions that Eowa was killed, not the side on which he fought, it has been speculated that Eowa was subject to Oswald and fighting alongside him in the battle, in opposition to Penda. Veneration and legacy Oswald soon came to be regarded as a saint. Bede says that the spot where he died came to be associated with miracles, and people took dirt from the site, which led to a hole being dug as deep as a man's height. Reginald of Durham recounts another miracle, saying that his right arm was taken by a bird (perhaps a raven) to an ash tree, which gave the tree ageless vigour; when the bird dropped the arm onto the ground, a spring emerged from the ground. Both the tree and the spring were, according to Reginald, subsequently associated with healing miracles. Aspects of the legend have been considered to have pagan overtones or influences—this may represent a fusion of
