"What think you?" he asked. "This is a warfare even more terrible than that we waged with the Goths in their forests. This Beric, who is their leader, has indeed profited by the lessons he learned at Camalodunum. No Roman general could have handled his men better. He is full of resources, and we did not reckon upon his breaking up the ice upon all these channels. If we have had so much trouble in forcing our way where the swamps are but two miles across, and that with a frost to help us, the task will be a terrible one when we get into the heart of the morasses, where they are twenty miles wide. Yet we cannot leave them untouched. There would never be peace and quiet as long as these bands, under so enterprising a leader, remained unsubdued. Can you think of any other plan by which we may advance with less loss?" The two officers were silent. "The resistance may weaken," one said after a long pause. "We have learnt from the natives that they have not in all much above three thousand fighting men, and they must have lost as heavily as we have." Suetonius shook his head. "I marked as we advanced," he said, "that there was not one British corpse to four Romans. We shoot at random, while they from their bushes can see us, and even when they charge us our archers can aid but little, seeing that the fighting takes place among the bushes. However, we will press on for a time. The natives behind us must clear the ground as fast as we advance, and every foot gained is gained for good." Three times during the night the British attacked the Romans, once by passing up the river in their coracles and landing behind them, once by marching out into the country round their left flank, and once by pouring out through cross channels in their boats and landing in front. All night, too, their shouts kept the Romans awake in expectation of attack. For four days the fighting continued, and the Romans, at the cost of over a thousand men, won their way eight miles farther. By the end of that time they were utterly exhausted with toil and want of sleep; the swamps each day became wider, and the channels larger and deeper. Then the Roman leaders agreed that no more could be done. Twelve miles had been won and cleared, but this was the mere tongue of the Fenland, and to add to their difficulties that day the weather had suddenly changed, and in the evening rain set in. It was therefore determined to retreat while the ground was yet hard, and having lighted their fires, and left a party to keep these burning and to deceive the British, the Romans drew off and marched away, bearing to the left so as to get out on to the plain, and to leave the ground, encumbered with the sharp stumps of the bushes and its network of channels, behind them as soon as possible.
