invaders were never safe except when within their own entrenchments; for they had now to deal with an enemy who had grown too wary to trust himself again in the open field, but contented himself by harassing and hanging upon the detached masses which he could waylay. He was well acquainted with all the secret passes and intricate roads, and kept the Roman guards in a continual state of alarm; and when it was not safe to attack them, the Britons would at times suddenly assemble at the outskirts of the woods, and shaking their javelins, to the foot of which a hollow ball of copper, containing lumps of metal or pebbles, was affixed, commence such a sudden thundering and shouting as startled the horses, and caused them to run affrighted in every direction; they then seized upon the forage, and ere the heavy legions could overtake them, they were off at full speed far away in the forest passes, along paths known only to themselves. Such a system of warfare was new even to Cæsar, and as yet he had only gained the ground he encamped upon--that which contained his army, for the time, was all he could call his own. But the Britons could not long remain true to themselves; petty jealousies and long-stifled murmurs began at last to find vent; one tribe after another came to the Roman camp; to all he made fair promises, took their corn and their hostages, sowing no doubt the seeds of dissension deeper amongst them at the same time, and getting them also to inform him where the capital of their warlike chief was situated, which secret they were base enough to betray; for many of the petty princes envied the renown which Cassivellaunus had won by his valour. Even Cæsar's narrative at this turn of events enlists our sympathies on the side of the British general, and the handful of brave followers who still remained true to their country's cause. His capital, which is supposed to have stood on the site of St. Albans, and which in those days was surrounded by deep woods and broad marshes, was attacked; many were slain, some prisoners taken, and numbers of cattle driven away; for the forest town of this courageous chief appears to have been nothing more than a cluster of woodland huts surrounded by a ditch, and strengthened by a rampart of mud and trees, a work which the Roman legions would level to the earth in a brief space of time. Though beaten and forced from his capital, the British prince retreated upon another fortress further into the wood; from this he was also driven. Still his great heart buoyed him up; and although defeated, he determined to have another struggle for the liberty of his unworthy country, and despatched messengers into Kent, bidding the Britons to fall at once upon the Roman camp and fleet. Had the prince himself been present, it is not improbable that this daring deed would have been executed, for he was unequalled in falling upon the enemy, and carrying his point by surprise: but he was not; and although the attack did
