The news had been sent rapidly along the chain of forts on either side of the swamp, and fifty men from each had been despatched to repair and reoccupy the camp, which was now held by a thousand men, who had already begun to repair the palisades that had been fired by the Britons.
This disaster at once depressed and infuriated the Roman soldiers, while it showed to the general commanding them that the task he had been appointed to perform was vastly more serious than he had expected. Already, as he had traversed mile after mile of the silent river, he had been impressed with the enormous difficulty there would be in penetrating the pathless morasses, extending as he knew in some places thirty or forty miles in width. The proof now afforded of the numbers, determination, and courage of the men lurking there still further impressed him with the gravity of the undertaking. Messengers were at once sent off to Suetonius, who was at Camalodunum, which he was occupied in rebuilding, to inform him of the reverse, and to ask for orders, and the general with five hundred men immediately set out for the camp of Godman.
Suetonius at once proceeded to examine for himself the extent of the Fen country, riding with a body of horsemen along the eastern boundary as far as the sea, and then, returning to the camp, followed up the western margin until he again reached the sea. He saw at once that the whole of the Roman army in Britain would be insufficient to guard so extensive a line, and that it would be hopeless to endeavour to starve out men who could at all times make raids over the country around them. The first step to be taken must be to endeavour to circumscribe their limits. Orders were at once sent to the British tribes in south and midlands to send all their available men, and as these arrived they were set to work to clear away by axe and fire the trees and bush on the eastern side of the river Ouse.
As soon as the intentions of the Romans were understood, the British camp at the junction of the rivers was abandoned, as with so large a force of workmen the Romans could have made wide roads up to it, and although it might have resisted for some time, it must eventually fall, while the Romans, by sending their flotilla of boats down, could cut off the retreat of the garrison. For two months thirty thousand workmen laboured under the eyes of strong parties of Roman soldiers, and the work of denuding the swamps east of the Ouse was accomplished.
Winter had now set in, but the season was a wet one, and although the Romans made repeated attempts to fire the brushwood from the south and west, they failed to do so. Severe frost accompanied by heavy snow set in late, and as soon as the ground was hard enough the Romans entered the swamps near Huntingdon, and began their advance northwards. The Britons were expecting them, and the whole of their fighting force had gathered to oppose them. Beric and Aska set them to work as soon as the Roman army crossed the river and marched north, and as the Romans advanced slowly and carefully through the tangled bushes, they heard a strange confused noise far ahead of them, and after marching for two miles came upon a channel, where the ice had been broken into fragments.
They at once set to work to cut down bushes and form them into faggots to fill up the gaps, but as they approached the channel with these they were assailed by volleys of arrows from the bushes on the opposite side. The light armed troops were brought up, and the work of damming the channel at a dozen points, was covered by a shower of javelins and arrows. The Britons, however, had during the past month made shields of strong wicker work of Roman pattern, but long enough to cover them from the eyes down to the ankles, and the wicker work was protected by a double coating of ox hide. Boys collected the javelins as fast as they were thrown, and handed them to the men. As soon as the road across the channel was completed the Romans poured over, believing that now they should scatter their invisible foes; but they were mistaken, for the Britons with levelled spears, their bodies covered with their bucklers, burst down upon them as they crossed, while a storm of darts and javelins poured in from behind the fighting line.
Again and again they were driven back, until after suffering great loss they made good their footing at several points, when, at the sound of a horn, resistance at once ceased, and the Britons disappeared as if by magic. Advancing cautiously the Romans found that the ice in all the channels had been broken up, and they were soon involved in a perfect network of sluggish streams. Across these the Britons had felled trees to form bridges for their retreat, and these they dragged after them as soon as they crossed. Every one of these streams was desperately defended, and as the line of swamp grew wider the Roman front became more and more scattered.
Late in the afternoon a sudden and furious attack was made upon them from the rear, Beric having taken a strong force round their flank. Numbers of the Romans were killed before they could assemble to make head against the attack, and as soon as they did so their assailants as usual drew off. After a long day's fighting the Romans had gained scarce a mile from the point where resistance had commenced, and this at a cost of over three hundred men. Suetonius himself had commanded the attack, and when the troops halted for the night at the edge of an unusually wide channel, he felt that the task he had undertaken was beyond his powers. He summoned the commanders of the two legions to the hut that had been hastily raised for him.
“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.
