Parties of men were at once sent down to hold the intrenchments erected to cover the approaches. Some of those who knew the swamps best were sent out singly, but they found the Romans everywhere. They had formed a complete circle round the island, all the channels being occupied by the boats, while parties had been landed upon planks thrown across the soft ground between the channels to prevent any from passing on foot. "They will not attack until broad daylight," Aska said, when all the men who had been sent out had returned with a similar tale. "They must fight under the disadvantage of not knowing the ground, and would fear that in the darkness some of us would slip away." Contrary to expectation the next day passed without any movement by the Romans, and Beric and Aska agreed that most likely the greater portion of the boats had gone back to bring up more troops. "They will not risk another defeat," Aska said, "and they must be sure that, hemmed in as we are, we shall fight to the last." The practicability of throwing the whole force against the Romans at one point, and of so forcing their way through was discussed; but in that case the women and children, over a thousand in number, must be left behind, and the idea was therefore abandoned. Another day of suspense passed. During the evening loud shouts were heard in the swamp, and the Britons had no doubt that the boats had returned with reinforcements. There were three points where boats could come up to the shore of the island. Aska, Boduoc, and another chief, each with a hundred men, took their posts in the intrenchments there, while Beric, with a hundred of the Sarci, remained in the great intrenchment on the summit, in readiness to bear down upon any point where aid was required. Soon after daybreak next morning the battle began, the Romans advancing in their flat bottomed boats and springing on shore. In spite of a hail of missiles they advanced against the intrenchments; but these were strongly built in imitation of the Roman works, having a steep bank of earth surmounted by a solid palisade breast high, and constructed of massive timber. For some hours the conflict raged, fifty of the defenders at each intrenchment thrusting down with their long spears the assailants as they strove to scale the bank, while the other fifty rained arrows and javelins upon them; and whenever they succeeded in getting up to the palisade through the circle of the spears, threw down their bows and opposed them sword in hand. Again and again the Romans were repulsed with great slaughter, the cries of exultation from the women who lined the upper intrenchment rose loud and shrill.
