They had attacked an entrenched legion because they were desperate. They must, I thought, be desperate indeed. It made no sense. Still, a couple of crucifixions would do them no harm and the rest would earn something in the slave market. Then the prefect pointed.
For a moment I thought it was a fiery serpent. Then I realized it was but a line of torches carried by men: but a long line. The Caledoni had crept upon us in the dark in force while a few of their number created a diversion.
I gave thanks that we were prepared, and by no means taken by surprise. But no battle against a wolfish people like the Caledoni, fighting at a time and place of their choosing, is a certain thing. And as a strategos should not, I fretted myself at that moment with fears about events I could no longer control. What if this was but a greater diversion, while other barbarians attacked the wall?
I looked impassive enough, as I rode forward through the camp with my staff officers and gallopers. Drums were rattling with the trumpets now, and as missiles and bolts began to fly I saw the shields going up as a testudo was formed. I gave thanks again for those centurions who needed no more than a word of command. The testudo would give protection from the arrows, spears, and the lighter missiles.
Then Roman and Caledoni stopped together.
The stars had changed again. Great lights moved in the sky, forming strange designs. Across a drifting cloud there appeared the picture of a Roman soldier in full armor. It was projected, I know now, by an ordinary sword- light, but the effect on all may be imagined. The gods themselves, both sides thought, had intervened. We Romans accepted this with pleasure and surprise, but also as something no more than our right, and certainly not as something to break discipline over. I knew Mithras was a good god for soldiers and was gratified. The Caledoni, as might be expected, too terror-stricken to run, stood wailing.
The testudo moved upon them, then dissolved into men with flickering swords. Rank upon rank, the legionaries advanced like the vast single-minded engine they were. They cheered and at the command surged forward. But it was a disciplined surge. The javelins of the front ranks flew in a dark mass, their swords flickered stabbing like the tongues of vipers. Crassus had not had them blacken the blades for night work, thinking the enemy ought to see the steel, and Crassus had been right.
As the Picts went down squealing, I thought: 'This will buy peace south of the wall, peace for Eboracum and Londinium. I have vindicated Hadrian's decision to build the wall.' Hadrian was reported dead but his successor might appreciate my contribution to the imperial numen.
Then the Jotoki ships began to descend. With their double torsion, scorpion bolts can penetrate iron armor, if not the molecularly bonded ceramics the Jotoki used. The Jotoki were forbearing. They burned the bolts in flight with sword-lights until we had no ammunition left, then began to talk to us. They fired a plasma jet to emphasize their words.
The Jotoki had done this, or something like this, before. They picked up a fair number of our womenfolk, and civilians, specialists, and other auxiliaries from the wall, and some Pictish villagers.
They say there are Roman soldiers garrisoning forts in China, who found their way there after their detachments were cut off by the Persians. It is easy to change masters when you have no choice in the matter.
Perpetua held up a hand. Marcus Augustus paused the film.
'This makes no sense,' she said. 'I have been searching the records in our ship's library. It's had all the major encyclopedias read into it. We know the Ninth Legion, the Hispania, marched north of the wall-it was newly built then-into Caledonia and was never seen again. But we know nothing of Jotoki raids along Hadrian's Wall.'
'What should we expect a primitive Earth historian to say?' asked Ginger. 'That giant starfish came from the sky and picked them up? He'd be kept in a little room at the top of the castle. House, I mean.'
'True enough. Perhaps it does make a kind of sense. Hadrian's Wall was suddenly extended and fortified about the time the Ninth Legion is said to have marched north. Then, after quite a short time, it was abandoned, and another work, the Antonine Wall, was built further north again. That was abandoned, too, after quite a short time, and the Romans fell back on Hadrian's Wall.
'The Romans put a huge effort into fortifying it and manning it-for about three hundred years. I gather scholars still disagree as to why. Maybe somebody did say something. And what of all the magic surrounding Arthur? Merlin and the flying dragons? And the Celtic myths? Flying, enchantments, magic weapons? Chesterton wrote in his history: 'Suddenly the soldier of civilization is no longer fighting Goths but Goblins.' After wars and invasions and race migrations, centuries of near-illiteracy, changes of languages, in a couple of non-technological millennia, what else might you expect to remain by way of memory of a Jotoki recruitment effort?'
'Millennia,' said Marcus to Perpetua. 'Two and a half thousand Earth years, you said.'
'Yes.'
'About nine hundred have passed for us, as far as we can tell. We traveled fast.'
'Then you didn't come directly here?' Ginger broke in. Marcus glanced at him but did not deign to reply.
'That is why your language has changed so little,' said Perpetua quickly. 'That and the fact you had no tongues of human invaders to overlay it. On Earth, six hundred years after your ancestors left, there were still fragments of the Western Empire extant in France. Latin was long the language of government and scholarship- where there was government and scholarship-and of the Church in Europe. The ruler in Ravenna still styled himself 'King of Rome, Emperor of the West,' and the Eastern Empire still had centuries of life ahead. You are almost contemporaries of Boethius.'
'We are still Romans! However far we have traveled! In the Mithraeum the Mysteries are still enacted. We honor our various gods. There are Jews in our ranks still, and fish-worshippers, but we have kept faith with Rome.'
The picture resumed.
You to whom I leave this story will know much of the ships that travel between worlds. I need not tell you of our awe and amazement, our initial disbelief, our wild thoughts that we were dead and in a Hades unlike any we had imagined, as we were taken aboard the great warship that the Jotoki named the Hard Bargainer, and its consort, the Shrewd Merchant, while about us flew as escort the Five Arms of the Wise Trade Councilor. These things you may imagine. But Roman or Caledonian, we were warriors, and we behaved as warriors. The centurions maintained discipline among our legionaries and civilians. The Caledonians wailed and howled in the manner of barbarians, but when they saw it availed them nothing they became tractable.
It was great good fortune that our political officers already knew the Caledonian chiefs and we could speak together. Thinking I had knowledge in the matter the Caledonian chiefs agreed, grudgingly enough, to place themselves under my direction. They, being barbarians, were of course far more overawed than we. But we saw that we were all human and that bound us together. The gold the Jotoki gave us helped, and the glass and beads and mirrors for the women, both Roman and Caledonian.
Meanwhile, we were heading away from Terra, our world, at a speed which the Jotoki told us was close to the speed of light itself, to do battle. The Jotoki had shown us representations of our enemies: great beasts like lions or Indian tigers, but armed as the Jotoki themselves were armed, with weapons of flame, and traveling like the Jotoki through the skies.
We had little love for the Jotoki then, though they fed us and clothed us and spoke to us in our own language (though at first only through images, not daring to confront us in the flesh). But then we realized that something the Jotoki told us many times was true:
Better we fight these felines far away than have them fall upon Terra.
The Jotoki told us first they were taking us to a new world to train us with new weapons and tactics to fight creatures which menaced them and which, if unchecked, would conquer our own world and Rome itself. After the campaign they would, if they were able, return us to our homes. We obviously had no choice but to believe them and obey.
Before we were placed in the chambers of deep sleep the Jotoki began to teach us of the heavens. They explained that they were traders and had taught other races before us. Once, said Jegarvindertsa, who talked to me most, they had tried to spread civilization among the stars.
' 'Civilization is our business.' Those were the old governor's words, when we marched north to the wall,' I recalled.
'You defend civilization now,' said Jegarvindertsa. 'This is but Rome writ large. It has been said there is only one civilization, and all civilized beings are a part of one another, almost as we Jotoki are compound entities. Are
