The Britains that dwelt about Chester, through their stoutnesse prouoked the aforesaid Edelferd king of the Northumbers vnto warre: wherevpon to tame their loftie stomachs, he assembled an armie & came forward to besiege the citie of Chester, then called of the Britains [Sidenote: Chester as yet in possession of the Britains. I. Leland. Wil. Malm.] Carleon ardour deue. The citizens coueting rather to suffer all things than a siege, and hauing a trust in their great multitude of people, came foorth to giue batell abroad in the fields, whome he compassing about with ambushes, got within his danger, and easilie discomfited.
[Sidenote: Beda.] It chanced that he had espied before the battell ioined (as Beda saith) where a great number of the British priests were got aside into a place somewhat out of danger, that they might there make their intercession to God for the good speed of their people, being then readie to giue battell to the Northumbers. Manie of them were of that [Sidenote: The number of moonks in the monasterie of Bangor.] famous monasterie of Bangor, in the which it is said, that there was such a number of moonks, that where they were diuided into seuen seuerall parts, with their seuerall gouernors appointed to haue rule ouer them, euerie of those parts conteined at the least three hundred persons, the which liued altogither by the labour of their hands. Manie therefore of those moonks hauing kept a solemne fast for three daies togither, were come to the armie with other to make praier, [Sidenote: Brocmale.] hauing for their defender one Brocmale or Broemael, earle (or consull as some call him) of Chester, which should preserue them (being giuen to praier) from the edge of the enimies swoord.
King Edelferd hauing (as is said) espied these men, asked what they were, and what their intent was; and being informed of the whole circumstance and cause of their being there, he said; “Then if they call to their God for his assistance against vs, suerlie though they beare no armour, yet doo they fight against vs, being busied in praier [Sidenote: The Britains discomfited & slaine.] for our destruction.” Wherevpon he commanded the first onset to be giuen them, and after slue downe the residue of the British armie, not without great losse of his owne people. Of those moonks and priests which came to praie (as before is mentioned) there died at that battell about the number of 12 hundred, so that fiftie of them onelie escaped by flight. Brocmale, or Broemael at the first approch of the enimies, turning his backe with his companie, left them (whom he should haue defended) to be murthered through the enimies swoord. Thus was the prophesie of Augustine fulfilled, though he was long before departed this life (as Beda saith.)
