The end came in the second week of May, a week hot with sunshine that seemed to come from June, and interrupted by showers left over from April—a borrowed week, and, for the Saxons, a debt called in by fate. Hengist, with his preparations for ambush half complete, was caught by Ambrosius at Maesbeli, near Conan’s Fort, or Kaerconan, that men sometimes call Conisburgh. This is a hilly place, with the fort on a crag, and a deep ravine running by. Here the Saxons had tried to prepare an ambush for Ambrosius’ force, but Ambrosius’ scouts got news of it from a Briton they came across lurking in a hilltop cave, where he had fled to keep his woman and two small children from the axes of the Northmen. So Ambrosius, forewarned, increased the speed of his march and caught up with Hengist before the ambush could be fully laid, thus forcing him into open battle.

Hengist’s attempt to lay an ambush had turned the luck against him; Ambrosius, where he halted and deployed his army, had the advantage of the land. His main force, Bretons, Gauls, and the island British from the south and south-west, waited on a gentle hill, with a level field ahead over which they could attack unimpeded. Among these troops, medleywise, were other native British who had joined him, with their leaders. Behind this main army the ground rose gently, broken only by brakes of thorn and yellow gorse, to a long ridge which curved to the west in a series of low rocky hills, and on the east was thickly forested with oak. The men from Wales—mountain men—were stationed mainly on the wings, the North Welsh in the oak forest and, separated from them by the full body of Ambrosius’ army, the South Welsh on the hills to the west. These forces, lightly armed, highly mobile and with scores to settle, were to hold themselves in readiness as reinforcements, the swift hammer-blows which could be directed during battle at the weakest points of the enemy’s defence. They could also be relied upon to catch and cut down any of Hengist’s Saxons who broke and fled the field.

The Saxon’s, caught in their own trap, with this immense winged force in front of them, and behind them the rock of Kaerconan and the narrow defile where the ambush had been planned, fought like demons. But they were at a disadvantage: they started afraid—afraid of Ambrosius’ reputation, of his recent ferocious victory at Doward, and more than both—so men told me—of my prophecy to Vortigern which had spread from mouth to mouth as quickly as the fires in Doward tower. And of course the omens worked the other way for Ambrosius. Battle was joined shortly before noon, and by sunset it was all over.
