The tribes longest conquered by the Romans first gave way, and the movement rapidly spread. Many for some time desperately opposed the advance of the Romans, whose triumphant shouts rose loudly; but gradually these melted away, and the vast crowd of warriors became a mob of fugitives, the Romans pressing hotly with cries of victory and vengeance upon their rear. Beric's little band was swept away like foam before the wave of fugitives. For a time it attempted to stem the current; but when Beric saw that this was in vain he shouted to his tribesmen to keep in a close body and to press towards the left, which was comparatively free. Fortunately the Roman horse had plunged in more towards the centre, and the ground was open for their retreat. Thousands of flying men were making towards the rear, but with a great effort they succeeded in crossing the tide of fugitives, and in passing through outside the semicircle of wagons. Here they halted for a moment while Beric, climbing on the end wagon, surveyed the scene. There was no longer any resistance among the Britons. The great semicircle within the line of wagons was crowded by a throng of fugitives behind whom, at a run now, the Roman legions were advancing, maintaining their order even at that rapid pace. Outside the sweep of wagons women with cries of terror were flying in all directions, and the horses, alarmed by the din, were plunging and struggling, while their drivers vainly endeavoured to extricate them from the close line of vehicles. "All is lost for the present," he said to Aska, "let us make for the north; it is useless to delay, men; to try to fight would be to throw away our lives uselessly, we shall do more good by preserving them to fight upon another day. Keep closely together, we shall have the Roman cavalry upon us before long, and only by holding to our ranks can we hope to repel them." Many of the women from the nearest wagons rushed in among the men, and, placing them in their centre, the band went off at a steady trot, which they could maintain for hours. The din behind was terrible, the shouts of the Romans mingled with the cries of the Britons and the loud shrieks of women. The plain was already thick with fugitives, consisting either of women from the outside wagons or men who had made their way through the mass of struggling animals. Here and there chariots were dashing across the plain at full gallop. Looking back from a rise of the ground a mile from the battlefield, they saw a few parties of the Roman horse scouring the plain; but the main body were scattered round the confused mass by the wagons.
