From Lyons it took me eight days to reach Boulogne by way of Troyes, Rheims, Soissons, and Amiens, for in the stage out of Rheims Xenophon forced me to use a sedan again. All this time I was not exactly idle. I was turning over in my mind my historical memories of great battles of the past – Julius’s battles, Hannibal’s battles, Alexander’s, and especially those of my father and brother in Germany – and wondering whether, when it came to the point, I should be able to apply all this detailed and extensive knowledge to any practical purpose. I congratulated myself that whenever it had been possible to draw a plan of any battle from the accounts handed down by eye-witnesses I had always done so; and had thoroughly mastered the general tactical principles involved in the use of a small force of disciplined fighters against a great army of semi-civilized tribesmen, and also the strategical principles involved in the successful occupation of their country when the battle had been won.
At Amiens, lying sleepless in the early morning, I began picturing the battle-field. The British infantry would probably be occupying a wooded ridge, with their cavalry and chariotry manoeuvring in the low ground in front. I would draw up my regular infantry in ordinary battle formation, on a two-regiment front, with the auxiliaries on either flank and the Guards in reserve. The elephants, which would be a complete novelty to the Britons, no such animal having ever been seen on that island – but here a most uncomfortable thought came to me. ‘Posides,’ I called, in an anxious voice.
‘Yes, Caesar,’ Posides answered, springing up from his pallet, half-asleep still.
‘The elephants are at Boulogne, aren’t they?’
‘Yes, Caesar.’
‘How long ago did I give you the order to move them up there from Lyons?’
‘When we heard news of the landing, Caesar; that would be on the seventh of August.’
‘And to-day is the twenty-seventh.’
‘Yes, Caesar.’
‘Then how in the world are we going to get those elephants over? We should have had special elephant transports built.’
‘The ship that brought the obelisk from Alexandria is at Boulogne.’
‘But I thought that it was still at Ostia.’
‘No, Caesar, at Boulogne.’
‘But if you sent it up there on the seventh it can’t possibly have arrived there yet. It can’t possibly be any nearer than the Bay of Biscay. It took three weeks to get to Rome from Egypt, you remember; in perfect sailing weather, too.’
But Posides was a really able minister. It appears that as soon as I had decided to put elephants among my reinforcements and sent them up to Lyons – in May, I think it was – he had considered the question of transport across the Channel and without saying a word to me had fitted up the obelisk-ship as an elephant-transport – it was the only ship big and strong enough for the purpose – and sent it up to Boulogne, where it had arrived six weeks later. If he had waited for my orders the elephants would have had to be left behind. The obelisk-ship deserves more than a passing mention. It was the largest vessel ever launched. It was no less than 200 feet long and broad in proportion, and its main timbers were of cedar. Caligula had built it in the first few months of his monarchy to bring from Egypt an eighty-foot red granite obelisk, together with four enormous stones which formed the pediment. The obelisk was originally from Heliopolis, but had been set up in Augustus’s temple at Alexandria a few years before. Caligula now wanted it set up in his own honour in the new Circus that he was building on the Vatican Hill. To understand what a monstrous sort of ship it was you must be told that its seventy-foot main mast was a silver fir eight feet in diameter at its base; and that among the ballast used to keep it steady when the obelisk and pediment were secured on deck were 120,000 pecks of Egyptian lentils – a gift for the people of Rome.
When I reached Boulogne I was delighted to find the troops in good spirits, the transports ready, and the sea calm. We embarked without delay, and our passage across the Channel was so pleasant and uneventful that on landing at Richborough I sacrificed to Venus and Neptune, thanking the latter for his unexpected favours and the former for her kindly intercession. The elephants gave no trouble. They were Indian elephants, not African. Indian elephants are about three times the size of African, and these were particularly fine ones which Caligula had bought for ceremonial use in his own religion: they had since been employed at the docks at Ostia moving timbers and stones under the direction of their Indian drivers. I found to my surprise that twelve camels had been added to the elephants. That was an idea of Posides’s.
Chapter 19
AT Richborough we were anxious to hear the latest news from Aulus, and I found a dispatch from him just arrived. It reported that the Britons had made two attacks, one by day and the other by night, on the camp which he had fortified just north of London, but had been beaten off with some loss. However, new enemy reinforcements seemed to be arriving every day, from as far west as South Wales; and the men of Kent who had retired into the Weald were reported to have sent a message through to Caractacus that as soon as Aulus was forced to retreat they would leave their woods and cut him off from his base. He begged me therefore to join forces with him as soon as possible. I talked to a few seriously wounded men whom Aulus had evacuated to the Base, and they all agreed that the British infantry was nothing to be afraid of, but that their chariotry seemed to be everywhere at once and was now so numerous as to prevent any force of less than 200 or 300 regular infantry from leaving the main body.
My column was now preparing for its advance. The elephants carried great bundles of spare javelins and other munitions of war; but certain curious machines slung across the back of the camels puzzled me.
‘An invention of your Imperial Predecessor, Caesar,’ Posides explained. ‘I took the liberty of having a set of six made at Lyons when we were there in July and sent up to Boulogne on camel-back. They’re a sort of siege-engine for use against uncivilized tribes.’
‘I didn’t know that the late Emperor had been responsible for any military inventions.’
‘I think, Caesar, that you will find this type of machine extremely effective, especially in conjunction with light rope. I have taken the liberty of bringing up several hundred yards of light rope in coils.’
Posides was grinning broadly, and I could see that he had some clever scheme at the back of his mind which he was keeping a secret from me. So I said to him: ‘Xerxes the Great had a war-minister called Hermotimus, a eunuch like you, and whenever Hermotimus was allowed to solve a tactical problem by himself, such as the reduction of an impregnable town without siege-engines or the crossing of an unfordable river without boats, that problem was always solved. But if Xerxes or anyone else tried to interfere with advice or suggestions Hermotimus used to say that the problem had now become too complicated for him and beg to be excused. You’re a second Hermotimus, and for good luck I am going to leave you to your own devices. Your forethought in the matter of the obelisk-ship has earned you my confidence. Understand that I expect great things from your camels and their loads. If you disappoint me I shall be greatly displeased with you and shall probably throw you to the panthers in the amphitheatre on our return.’
He answered, still grinning: ‘And if I help to win the victory for you, what then?’
‘Then I’ll decorate you with the highest honour that it is in my power to bestow and one not inappropriate to your condition: you shall be awarded the Untipped Spear. Have you any other novelties smuggled away in the baggage? These camels and elephants and black spearmen from Africa already suggest a spectacle on Mars Field rather than a serious expedition.’
‘No, Caesar, nothing else much. But I think that the Britons will have an eyeful before we have done, and we can collect the entrance money after the performance is over.’
We marched up from Richborough and met with no opposition: the river-crossings were held for us by detachments of the Fourteenth sent back by Aulus for this purpose. When we had passed they fell in behind us. I did not s
ee a single enemy Briton between Richborough and London, where Aulus and I joined forces on the fifth of September. I think that he was as pleased to see me as I was to see him. The first thing I asked him was whether the troops were in good spirits. He answered that they were and that he had only promised them half the forces that I had brought, and had not mentioned the elephants, so that our real strength was a surprise to them. I asked him where the enemy were expected to give battle, and he showed me a contour map he had made in clay of the country between London and Colchester. He pointed out a place about twenty miles along the London-Colchester road – not a road in the Roman sense, of course – which Caractacus had been busily fortifying and which would almost certainly be the site of the coming battle. This was a wooded ridge called Brentwood Hill, which curved round the road in a great horseshoe, at each tip of which was a great stockaded fort, with another in the centre. The road ran north-east. The enemy’s left flank beyond the ridge was protected by marshland, and a deep brook, called the Weald Brook, formed a defendable barrier in front. On the right flank the ridge bent round to the north and continued for three or four miles, but the trees and thorn bushes and brambles grew so densely along it that to try to turn that flank by sending a force of men to hack their way through would, Aulus assured me, be useless. Since the only feasible approach to Colchester was by this road, and since I wished to engage the main forces of the enemy as soon as possible, I studied the tactical problem involved very carefully. Prisoners and deserters volunteered precise information about the defences in the wood and these seemed to be extremely well planned. I did not welcome the notion of making a frontal attack. If we marched against the central fort without first reducing the other two we would be exposed to heavy attacks from both flanks. But to attack the other two first would not help us much either; for if we succeeded in taking them, at great cost to ourselves, it would mean fighting our way through a series of further stockades inside the wood, each of which would have to be taken in a separate operation.
At a council of war to which Aulus and I summoned all general staff-officers and regimental commanders, everyone agreed that a frontal attack on the central fort was inevitable, and that we must be prepared to suffer heavy losses. It was unfortunate that the forward slopes of the ridge between the wood and the stream were admirably suited to chariot-manoeuvre. Aulus recommended a mass attack in diamond formation. The head of the diamond would consist of a single regiment in two waves, each wave eight men deep. Then would follow two regiments marching abreast, in the same formation as the leading one; then three regiments marching abreast. This would be the broadest part of the diamond and here the elephants would be disposed as a covering for each flank. Then would come two regiments, again, and then one. The cavalry and the rest of the infantry would be kept in reserve. Aulus explained that this diamond afforded a protection against charges from the flank: no attack could be made on the flank of the leading regiment without engaging the javelin-fire of the overlapping second line, nor on the second line without engaging the fire of the overlapping third. The third line was protected by the elephants. If a heavy chariot charge was made from a rear flank the regiments there could be turned about and the same mutual protection given.
My comments on this diamond were that it was a pretty formation and that it had been used successfully in such and such battles – I listed them – in republican times; but that the Britons outnumbered us so greatly that once we had advanced into the centre of the horse-shoe they could attack us from all sides at once with forces that we could not drive off without disorganization: the front of the diamond would almost certainly become separated from the rear. I said too, very forcibly, that I was not prepared to suffer one-tenth of the number of casualties that it had been estimated the frontal attack would cost. Vespasian came out with the old proverb about not being able to make an omelette without breaking eggs, and asked somewhat impatiently whether I proposed to cut my losses and return to France immediately, and how long, if so,’ I expected to keep the respect of the armies.
I countered with: ‘There are more ways of killing a cat than beating it to death with a horn porridge-spoon; and breaking the spoon into the bargain.’
They argued with me in the superior way of old campaigners, trying to impress me with technical military terms, as though I were an entire ignoramus. I burst out angrily: ‘Gentlemen, as the God Augustus used to say, “A radish may know no Greek, but I do”. I have been studying tactics for forty years and you can’t teach me a thing: I know all the conventional and unconventional moves and openings in the game of human draughts. But you must understand that I am not free to play the game in the way you wish me to play it. As Father of the Country I now owe a duty to my sons: I refuse to throw away three or four thousand of their lives in an attack of this sort. Neither my father Drusus nor my brother Germanicus would ever have dreamed of making a frontal attack against a position as strong as this.’
Geta asked, perhaps ironically: ‘What would your noble relatives have done, Caesar, in a case of this sort, do you think?’
‘They’d have found a way round.’
‘But there is no way round here, Caesar. That has been established.’
‘They’d have found a way round, I say.’
Crassus Frugi said: ‘The enemy’s left flank is guarded by the Heron King and their right by the Hawthorn Queen. That’s their boast, according to prisoners.’
‘Who’s this Heron King?’ I asked.
‘The Lord of the Marshes. He’s a cousin, in their mythology, of the Goddess of Battle. She appears in the disguise of a raven and perches on the spear-heads. Then she drives the conquered into the marshes, and her cousin the Heron King eats them up. The Hawthorn Queen is a virgin who dresses in white in the spring and helps soldiers in battle by defending their stockades with her thorns: you see, they fell thorn-trees and pile them in a row with the thorns outwards, making the trunks fast together. That’s a fearful obstacle to get through. But the Hawthorn Queen holds that right flank of theirs without any artificial felling of trees. Our scouts are positive that the whole wood is in such a fearful tangle that it’s no use trying to get through at any point there.’
Aulus said: ‘Yes, Caesar, I am afraid that we must make up our minds to that frontal attack.’
‘Posides,’ I suddenly called, ‘were you ever a soldier?’
‘Never, Caesar.’
‘That makes two of us, thank God. Now suppose I undertake to do the impossible and get our cavalry through on the enemy’s right flank, past this impenetrable tangle of thorns, can you undertake to get the Guards round on their left through that impassable bog?’
Posides answered: ‘You have given me the easier flank, Caesar. There is, as it happens, a track through the marshes. One would have to go along it in single file, but there is a track. I met a man in London yesterday, a travelling Spanish oculist, who goes about the country curing the people of marsh-ophthalmia. He’s in the Camp now, and he says he knows that marsh well, and the track – which he always uses to avoid the tollgate on the hill. Since Cymbeline’s death they have been levying no fixed toll, but a traveller must pay according to the amount of money he has in his saddlebags, and this oculist got tired of being skinned. In the early mornings there’s nearly always a mist on the marsh and he takes the path and slips round unobserved. He says that it’s easy to follow once you are on it. It comes out half a mile beyond the ridge, at the edge of a pine copse. The Britons are likely to have a guard posted at that end – Caractacus is a careful general – but I think now that I can undertake to dislodge them and get as many men across the marsh as care to follow me.’
He explained his ruse, which I approved, though many of the generals raised their eyebrows at it; and then I explained my plan for forcing the other flank, which was really very simple. An important fact had been overlooked in the general concentration of interest on the diamond formation; the fact that Indian elephants are capable of bursting through the densest u
ndergrowth imaginable and are daunted by no briars or thorns. However, in order not to tell the story twice, I shall say no more about the council of war and what was decided at it. I shall proceed to the battle, which took place at Brentwood on the seventh of September, a date that had long been memorable to me as the day on which my brother Germanicus had defeated Hermann at the Weser: if he had lived he would still have been only fifty-eight years old, which was no older than Aulus.
We marched out from London along the Colchester road. Our vanguard was kept busy by British skirmishers, but no serious resistance was offered until we reached Romford, a village about seven miles from Brentwood, where we found the ford across the River Rom strongly defended. The enemy held us up there for a whole morning, at the cost to themselves of 200 killed and 100 prisoners. We lost only fifty, but two of these were captains and one a battalion commander, so in a sense the Britons got the best of the exchange. That afternoon we sighted Brentwood Ridge and encamped for the night this side of the brook, which we used as a defensive barrier.
I took the auspices. Auspices are always taken before battle by giving the sacred chickens lumps of pulse-cake and watching how they eat it. If they have no appetite the battle is already as good as lost. The best possible omen is when the chickens, as soon as the cage-door is opened by the chicken-priest, rush out without any cry or beating of wings and eat so greedily that big bits drop from their mouths. If the sound of these striking the ground can be distinctly heard it prophesies the total defeat of the enemy. And, sure enough, this best possible omen was granted. The chicken-priest did not show himself to the birds, but standing with me behind the cage suddenly slid the door back at the very moment that I threw the cake before them. Out they rushed, without so much as a cackle, and fairly tore at the cake, throwing lumps about in a way which absolutely delighted us all, it was so reckless.
