The details of this bloody encounter, as we gather them from the Poem, were as follow: At the call of Mynyddawg, lord of Eiddin, whose dominions lay peculiarly exposed, both by sea and land, to the attack of the enemy, the native chieftains of Prydyn, aided by many of their relatives and friends from Gwynedd and Cernyw, entered into a mutual alliance in behalf of their common country. {6a} In one place the daughter of Eudav {6b} is joined with Mynyddawg, as one upon whose errand the expedition was undertaken, but whether she was his wife, or ruled over a territory adjacent to, or equally threatened with his own, does not appear. The troops under their respective leaders arrived at Eiddin, where they were sumptuously entertained by Mynyddawg, {6c} and where they established their head quarters. The generals named in the Poem amount in number to about ninety, but this was not the third part of the whole, which consisted of “three hundred and sixty three chieftains wearing the golden torques.” {6d} The aggregate number of men that followed these illustrious leaders is not told, but if an average may be formed from what we know respecting a few cases, it will appear to have been immense. Mynyddawg’s retinue consisted of “three hundred;” {6e} there were “five battalions of five hundred men each,” “three levies of three hundred each;” “three bold knights” had each “three hundred of equal quality;” {6f} thus averaging about four hundred for each commander, which, multiplied by three hundred and sixty three, would exhibit an overwhelming army of a hundred and forty five thousand, and two hundred men! Yet the Poet describes the numerical advantages possessed by the enemy as greatly superior. These forces, being all placed on the western side of the dyke, would approach the land of their enemies as they marched to the field of battle, hence the reason why Aneurin uses the expressions “Gwyr a aeth Gattraeth,” and “Gwyr a aeth Gododin,” as synonymous. The enemies, as before observed, were the Saxons, aided on this occasion by many of the Lloegrians, namely, such of the natives as had submitted to their sway in the provinces they had already conquered. They concentrated their forces in Gododin, and marched westward in the direction of the great fence, where the Britons were awaiting them. Aneurin has not thought fit to record the names of any of their generals, with the single exception of Dyvnwal Vrych, {7a} who, to entitle him to that distinction, must have figured prominently on the field of battle.
