I have said too much, I think, but I can trust you, my dear mother, not to let the story go any farther. Burn this when you have read it.
There was no more news from Marsus and I did not get an answer from Herod himself before I sailed for Britain for, a fortnight after: landing, Aulus was indeed obliged to send for me. But I reckoned that Herod would read between the lines of my letter that I suspected him, though I was careful not to mention
Marsus in it, or the wedding celebrations at Tiberias; and that he would be very careful about his next step. I also strengthened the garrison at Alexandria and told Marsus to call up all Greek levies in Syria and give them an intensive drilling letting the rumour go about that a Parthian invasion was expected. He was to do this as if on his own initiative, and not to tell anyone that the orders came from me.
Chapter 18
AULUS, as I have already related, landed in Britain without meeting any opposition. He built a strong base camp at Richborough, which he garrisoned with veterans from each regiment, pulled up his transport on the shore, well out of the reach of storms, and began a cautious advance through Kent, taking the route followed by Julius on his second expedition - the route indeed that all the invaders of the island have naturally, taken. At first he met with less resistance than Julius, because the passage: of the Stour did not need to be forced. The King of East Kent, a vassal of Caractacus and Togodumnus, decided not to man the prepared positions there. His overlords had withdrawn their main army to Colchester when they heard that our invasion could not possibly take place that-year, and his own forces were insufficient to defend the river successfully. He came to meet Aulus with tokens of peace and after an exchange of presents swore alliance and friendship with Rome. The King of East Sussex, which lies to the west of Kent, came into camp on the same errand a few days later. Between the Stour and the River Medway, the next natural barrier, Aulus encountered little serious resistance. But small parties of chariot-fighters disputed the frequent barriers of felled trees and thorn bushes that had been thrown across the track. Aulus's advance-guard commander was now instructed not to force these barriers, but as soon as they were sighted to envelop them with cavalry detachments and capture the defenders. This slowed down progress, but no lives were wasted. Most of the Kentish men seemed to have retired into the Weald - thick forest-land from which it would be most difficult to dislodge them. But increasingly large forces of chariotry began to appear on the flanks of the advancing column, charging down on foraging parties and forcing them to fall back on the main body. Aulus was aware that the mood in which the Kentish men would finally emerge from the Weald, whether meekly to offer their submission or valiantly to cut off his retreat, depended on his success against the Catuvellaunians. However, his base camp was well defended.
When he came to the tidal reaches of the Medway, which Julius, in his second campaign, had forded without loss, he found the enemy assembled in great force behind positions that had been prepared; some months before. Caractacus and Togodumnus were both present with all their tributary princes and an army of some 60,000 men. Aulus had no more than 35,000 effectives with him. The narrow ford, across the river had been made practically impassable by a succession of deep wide channels cut across it parallel with the banks. The Britons were bivouacked in a careless fashion on, the other, side. The nearest ford upstream was a day's march away and was reported by prisoners to be similarly fortified. Downstream there was no ford: the river, after debouching into the Thames estuary not far from this spot, spread out across impassable mud-flats. Aulus set his men to work at making the ford passable, filling in the channels with basketfuls of rubble. But it was clear that at this rate two or three days would pass before he could attempt to cross. The enemy bank was defended by two strong stockades; and the Britons, who now harassed the workers with arrows and insults, were building a third one behind that. Twice a day a huge tide welled up into the river mouth a commonplace in this part of the world, though never seen in the Mediterranean, except during storms and hindered Aulus's work greatly. But he was counting on the tide as his ally. At high tide, just before dawn on the third day, he sent the Batavian auxiliaries swimming across the motionless water. All Germans swim well, and the Batavians better than any. They swam across, 3,000 strong, with their weapons tied on their backs, and caught the Britons completely by surprise. However, instead of attacking the startled men at their camp-fires, they rushed to the horse-lines and began disabling the chariot-ponies, putting 2,000 or 3,000 of these out of action before their owners realized what was happening. They then established themselves at the enemy end of the ford behind the middle barricade, which had been designed to face the other way, and held it against strong British attacks while two battalions of the Ninth Regiment struggled across the river to their assistance, on blown-up wine-skins and improvised rafts and in captured British coracles. The struggle was a fierce one, and the British detachments posted higher up the stream, to prevent our men from crossing at any point there, came charging down to take part in the fight. Aulus saw what was happening, and detailed the Second under a certain Vespasian* to go upstream under cover of a forest and cross over at some now unguarded bend. Vespasian found the right place four or five miles upstream where the river narrowed somewhat and sent a man swimming over with a line. The line served to pull a rope across, which was made fast to a tree on either bank and then tautened. The Second were trained to this manoeuvre and were all across the river in an hour or two. Numerous ropes had to be used, because the distance was so great that to keep any one rope taut enough to hold the weight of more than twenty or thirty heavily armed men at a time was to risk it snapping. Once over, they hurried downstream, meeting none of the enemy as they went, and an hour later suddenly appeared on the enemy's unprotected right flank. They locked shields, shouted, and burst right through to the' stockade, killing hundreds of British tribesmen in a single charge. The Batavians and the men of the Ninth joined forces with the Second; and
