That evening Beric had a long talk with Aska and four or five men from the coast accustomed to the building of large boats. The matter would be easy enough, they said, as the boats would not be required to withstand the strain of the sea, and needed only to be put together with flat bottoms and sides. With so large a number of men they could hew down trees of suitable size, and thin them down until they obtained a plank from each. They would then be fastened together by strong pegs and dried moss driven in between the crevices. Pitch, however, would be required to stop up the seams, and of this they had none.  
"Then," Beric said, "we must make some pitch. There is no great difficulty about that. There are plenty of fir trees growing near the edges of the swamps, and from the roots of these we can get tar."
 
The men were all acquainted with the process, which was a simple one. A deep hole was dug in the ground. The bottom of this was lined with clay, hollowed out into a sort of bowl. The hole was then filled with the roots of fir closely packed together. When it was full a fire was lit above it. As soon as this had made its way down earth was piled over it and beaten down hard, a small orifice being left in the centre. In this way the wood was slowly converted into charcoal, and the resin and tar, as they oosed out under the heat, trickled down into the bowl of clay at the bottom. As little or no smoke escaped after the fire was first lighted, the work could be carried on without fear of attracting the attention of any bodies of the enemy who might be searching the country.
 
Two months passed. By the end of that time the intrenchment on the river bank had been made so strong that it could resist any attack save by a very large body of men. That on the island had also been completed, and strong banks thrown up at the only three points where a landing could be effected from boats.
 
The swamps had been thoroughly explored in the neighbourhood, and another island discovered, and on this three hundred men had been established, while four hundred remained on the great island, and as many in the camp on the river. There were over a thousand women and children distributed among the three stations. Three hundred men had laboured incessantly at the boats, and these were now finished. While all this work had been going on considerable numbers of fish and wildfowl had been obtained by barter from the Fenmen, with whom they had before had dealings, and from other communities living among the swamps to the north. Many of the Iceni, who came from the marshy districts of the eastern rivers, were also accustomed to fishing and fowling, and, as soon as the work on the defences was finished and the tortuous channels through the swamps became known to them, they began to lay nets, woven by the women, across the streams, and to make decoys and snares of all sorts for the wildfowl.
 
The framework for many coracles had been woven of withies by the women, and the skins of all the cattle killed were utilized as coverings, so that by the end of the two months they had quite a fleet of little craft of this kind. As fast as the larger boats were finished they were used for carrying cattle to the islands, and a large quantity of swine were also taken over.
 
During this time the Romans had traversed the whole country of the Iceni. The hamlets were fired, and all persons who fell into their hands put to death; but the number of these was comparatively small, as the greater part of the population had either moved north or taken to the woods, which were so extensive that comparatively few of the fugitives were killed by the search parties of the Romans. From the few prisoners that the Romans took they heard reports that many of the Iceni had taken refuge in the swamps, and several strong bodies had moved along the edge of the marsh country without attempting to penetrate it.
 
Aska and Beric had agreed that so long as they were undisturbed they would remain quiet, confining themselves to their borders, except when they sent parties to search for cattle in the woods or to gather up grain that might have escaped destruction in the hamlets, and that they would avoid any collision with the Romans until their present vigilance abated or they attempted to plant settlers in their neighbourhood.
 
Circumstances, however, defeated this intention. They learned from the Fenmen that numerous fugitives had taken refuge in the southern swamps, and that these sallying out had fallen upon parties of Romans near Huntingdon, and had cut them to pieces. The Romans had in consequence sent a considerable force to avenge this attack. These had penetrated some distance into the swamps, but had there been attacked and driven back with much slaughter. But a fortnight later a legion had marched to Huntingdon, and crossing the river there had established a camp opposite, which they called Godmancastra, and, having collected a number of natives from the west, were engaged in building boats in which they intended to penetrate the swamp country and root out the fugitives.
 
"It was sure to come sooner or later," Aska said to Beric. "Nor should we wish it otherwise. We came here not to pass our lives as lurking fugitives, but to gather a force and avenge ourselves on the Romans. If you like I will go up the river and see our friends there, and ascertain their strength and means of resistance. Would it be well, think you, to tell them of our strong place here and offer to send our boats to bring them down, so that we may make a great stand here?"
 
"No, I think not," Beric said. "Nothing would suit the Romans better than to catch us all together, so as to destroy us at one blow. We know that in the west they stormed the intrenchments of Cassivellaunus, and that no native fort has ever withstood their assault. I should say that it ought to be a war of small fights. We should attack them constantly, enticing them into the deepest parts of the morass, and falling upon them at spots where our activity will avail against their heavily weighted men. We should pour volleys of arrows into their boats as they pass along through the narrow creeks, show ourselves at points where the ground is firm enough for them to land, and then falling back to deep morasses tempt them to pursue us there, and then turn upon them. We should give them no rest night or day, and wear them out with constant fighting and watching. The fens are broad and long, stretching from Huntingdon to the sea; and if they are contested foot by foot, we may tire out even the power of Rome."
 
"You are right, Beric; but at any rate it will be well to see how our brethren are prepared. They may have no boats, and may urgently need help."
 
"I quite agree with you, and I think it would be as well for you to go. You could offer to bring all their women and children to our islands here, and then we would send down a strong force to help them. We should begin to contest strongly the Roman advance from the very first."
 
Accordingly Aska started up the Ouse in one of the large boats with twelve men to pole it along, and three days afterwards returned with the news that there were some two thousand men with twice that many women and children scattered among the upper swamps.
 
"They have only a few small boats," he said, "and are in sore straits for provisions. They drove at first a good many cattle in with them, but most of these were lost in the morasses, and as there have been bodies of horse moving about near Huntingdon, they have not been able to venture out as we have done to drive in more."
 
"Have they any chief with them?" Beric asked.
 
"None of any importance. All the men are fugitives from the battle, who were joined on their way north by the women of the villages. They are broken up into groups, and have no leader to form any general plan. I spoke to the principal men among them, and told them that we had strongly fortified several places here, had built a fleet of boats, and were prepared for warfare; they will all gladly accept you as their leader. They urgently prayed that we would send our boats down for the women and children, and I promised them that you would do so, and would also send down some provisions for the fighting men."
 
The next morning the twenty large boats, each carrying thirty men and a supply of meat and grain, started up the river, Beric himself going with them, and taking Boduoc as his lieutenant. Aska remained in command at the river fort, where the force was maintained at its full strength, the boat party being drawn entirely from the two islands. Four miles below Huntingdon they landed at a spot where the greater part of the Iceni there were gathered. Fires were at once lighted, and a portion of the meat cooked, for the fugitives were weak with hunger. As soon as this was satisfied, orders were issued for half the women and children to be brought in.
 
These were crowded into the boats, which, in charge of four men in each, then dropped down the stream, Beric having given orders that the boats were to return as soon as the women were landed on the island. He spent the next two days in traversing the swamps in a coracle, ascertaining where there was firm ground, and where the morasses were impassable. He learned all the particulars he could gather about the exact position of the Roman camp, and the spot where the boats were being constructed--the Iceni were already familiar with several paths leading out of the morasses in that neighbourhood--and then drew out a plan for an attack upon the Romans.
 
He had brought with him half the Sarci who had retired with him from the battle. These he would himself command. A force of four hundred men, led by Boduoc, were to travel by different paths through the swamp; they were then to unite and to march round the Roman camp, and attack it suddenly on three sides at once.
 
The camp was in the form of a horseshoe, and its ends resting on the river, and it was here that the boats were being built. Beric himself with his own hundred men and fifty others were to embark in four boats. As soon as they were fairly beyond the swamp, they were to land on the Huntingdon side, and to tow their boats along until within two or three hundred yards of the Roman camp, when they were to await the sound of Boduoc's horn. Boduoc's instructions were that he was to attack the camp fiercely on all sides. The Roman sentries were known to be so vigilant that there was but slight prospect of his entering the camp by surprise, or of his being able to scale the palisades at the top of the bank of earth. The attack, however, was to be made as if in earnest, and was to be maintained until Beric's horn gave the signal for them to draw off, when they were to break up into parties as before, and to retire into the heart of the swamp by the paths by which they had left it.
 
The most absolute silence was to be observed until the challenge of the Roman sentries showed that they were discovered, when they were to raise their war shouts to the utmost so as to alarm and confuse the enemy.
 
The night was a dark one and a strong wind was blowing, so that Beric's party reached their station unheard by the sentries on the walls of the camp. It was an hour before they heard a distant shout, followed instantly by the winding of a horn, and the loud war cry of the Iceni. At the same moment the trumpets in the Roman intrenchments sounded, and immediately a tumult of confused shouting arose around and within the camp. Beric remained quiet for five minutes till the roar of battle was at its highest, and he knew that the attention of the Romans would be entirely occupied with the attack. Then the boats were again towed along until opposite the centre of the horseshoe; the men took their places in them again and poled them across the river.
 
The fifty men who accompanied the Sarci carried bundles of rushes dipped in pitch, and in each boat were burning brands which had been covered with raw hides to prevent the light being seen. They were nearly across the river when some sentries there, whose attention had hitherto been directed entirely to the walls, suddenly shouted an alarm. As soon as the boats touched the shore, Beric and his men leapt out, passed through the half built boats and the piles of timber collected beside them, and formed up to repel an attack. At the same moment the others lighted their bundles of rushes at the brands, and jumping ashore set fire to the boats and wood piles. Astonished at this outburst of flame within their camp, while engaged in defending the walls from the desperate attacks of the Iceni, the Romans hesitated, and then some of them came running down to meet the unexpected attack.
 
But the Sarci had already pressed quickly on, followed by some of the torch bearers, and were in the midst of the Roman tents before the legionaries gathered in sufficient force to meet them. The torches were applied to the tents, and fanned by the breeze, the flames spread rapidly from one to another. Beric blew the signal for retreat, and his men in a solid body, with their spears outward, fell back. The Romans, as they arrived at the spot, rushed furiously upon them; but discipline was this time on the side of the Sarci, who beat off all attacks till they reached the river bank. Then in good order they took their places in the boats, Beric with a small body covering the movement till the last; then they made a rush to the boats; the men, standing with their poles ready, instantly pushed the craft into the stream, and in two minutes they were safe on the other side.
 
The boats and piles of timber were already blazing fiercely, while the Roman camp, in the centre of the intrenchment, was in a mass of flames, lighting up the helmets and armour of the soldiers ranged along the wall, and engaged in repelling the attacks of the Iceni. As soon as the Sarci were across, they leapt ashore and towed the boat along by the bank. A few arrows fell among them, but as soon as they had pushed off from the shore most of the Romans had run back to aid in the defence of the walls. Beric's horn now gave the signal that the work was done, and in a short time the shouts of the Iceni began to subside, the din of the battle grew fainter, and in a few minutes all was quiet round the Roman camp.
 
There was great rejoicing when the parties of the Iceni met again in the swamp. They had struck a blow that would greatly inconvenience the Romans for some time, would retard their attack, and show them that the spirit of the Britons was still high. The loss of the Iceni had been very small, only some five or six of Beric's party had fallen, and twenty or thirty of the assailants of the wall; they believed that the Romans had suffered much more, for they could be seen above their defences by the light of the flames behind them, while the Iceni were in darkness. Thus the darts and javelins of the defenders had been cast almost at random, while they themselves had been conspicuous marks for the missiles of the assailants.
 
In Beric's eyes the most important point of the encounter was that it had given confidence to the fugitives, had taught them the advantage of fighting with a plan, and of acting methodically and in order. There was a consultation next morning. Beric pointed out to the leaders that although it was necessary sometimes with an important object in view to take the offensive, they must as a rule stand on the defensive, and depend upon the depth of their morasses and their knowledge of the paths across them to baffle the attempts of the Romans to penetrate.
 
"I should recommend," he said, "that you break up into parties of fifteens and twenties, and scatter widely over the Fen country, and yet be near enough to each other to hear the sound of the horn. Each party must learn every foot of the ground and water in the neighbourhood round them. In that way you will be able to assemble when you hear the signal announcing the coming of the Romans, you will know the paths by which you can attack or retreat, and the spots where you can make your way across, but where the Romans cannot follow you. Each party must earn its sustenance by fishing and fowling; and in making up your parties, there should be two or three men in each accustomed to this work. Each party must provide itself with coracles; I will send up a boat load of hides. Beyond that you must search for cattle and swine in the woods, when by sending spies on shore you find there are no parties of Romans about.
 
"The parties nearest to Huntingdon should be always vigilant, and day and night keep men at the edge of the swamp to watch the doings of the Romans, and should send notice to me every day or two as to what the enemy are doing, and when they are likely to advance. Should they come suddenly, remember that it is of no use to try to oppose their passage down the river. Their boats will be far stronger than ours, and we should but throw away our lives by fighting them there. They may go right down to the sea if they please, but directly they land or attempt to thrust their boats up the channels through the swamp, then every foot must be contested. They must be shot down from the bushes, enticed into swamps, and overwhelmed with missiles. Let each man make himself a powerful bow and a great sheath of arrows pointed with flints or flakes of stone, which must be fetched from the dry land, although even without these they will fly straight enough if shot from the bushes at a few yards' distance.
