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.
