Quintus looked very put out, and from that moment on effectively washed his hands of the whole operation, so much so that when Cicero suggested he should join Flaccus and Pomptinus at the bridge, he replied sulkily that it was clear his advice was not needed.
'In that case I shall have to go myself,' said Cicero, but everyone immediately objected to that on the grounds that it was not safe. 'Then it will have to be Tiro,' he concluded, and seeing my look of horror, he added: 'Someone has to be there who isn't a soldier. I shall need a clear account written up by an eyewitness that I can give to the senate tomorrow, and Flaccus and Pomptinus will be too busy directing operations.'
'What about Atticus?' I suggested – somewhat impertinently, I realise now, but fortunately for me, Cicero was too preoccupied to notice.
'He'll be in charge of my security in Rome, as usual.' Behind his back, Atticus shrugged at me apologetically. 'Now, Tiro, make sure you write down everything they say, and above all else, secure those letters with their seals unbroken.'
We set off on horseback well after darkness fell: the two praetors, their eight lictors, another four guards, and finally and reluctantly, me. To add to my woes I was a terrible rider. I bounced up and down in my saddle, an empty document case banging against my back. We clattered over the stones and through the city gate at such speed, I had to wind my fingers into the mane of my poor mare to stop myself falling off. Fortunately she was a tolerant beast, no doubt especially reserved for women and idiots, and as the road stretched down the hill and across the plain, she plunged on without requiring guidance from me, and so we managed to keep pace with the horses ahead of us.
It was one of those nights when the sky is an adventure all to itself, a brilliant moon racing through motionless oceans of silvery cloud. Beneath this celestial odyssey, the tombs lining the Via Flaminia silently flickered as if in a lightning storm. We trotted along steadily until, after about two miles, we came to the river. We drew to a halt and listened. In the darkness I could hear rushing water, and looking ahead I could just make out the flat roofs of a couple of houses and the silhouettes of trees, sharp against the hurtling sky. From somewhere close by a man's voice demanded the password. The praetors replied – 'Aemilius Scaurus!' – and suddenly, from both sides of the road, the men of the Reate century rose out of the ditches, their faces blackened with charcoal and mud. The praetors quickly divided this force in two. Pomptinus with his men was to remain where he was, while Flaccus led forty legionaries over to the opposite bank. For some reason it seemed to me safer to be with Flaccus, and I followed him on to the bridge. The river was wide and shallow and flowing very fast across the big flat rocks. I peered over the edge of the parapet to where the waters crashed and foamed against the pillars more than forty feet below, and I realised what an effective trap the bridge made, that jumping in to avoid capture would be an act of suicide.
In the house on the far bank there was a family asleep. At first they refused to let us in, but their door soon flew open when Flaccus threatened to break it down. They had irritated him so he locked them in the cellar. From the upstairs room we had a clear view of the road, and here we settled down to wait. The plan was that all travellers, from whichever direction, would be allowed on to the bridge, but that once they reached the other side they would be challenged and questioned before being allowed off it. Long hours passed and not a soul approached, and the conviction steadily grew in me that we must have been tricked. Either there was no party of Gauls heading out of the city that night, or they had already gone, or they had chosen a different route. I expressed these doubts to Flaccus, but he shook his grizzled head. 'They will come,' he said, and when I asked why he was so certain, he replied: 'Because the gods protect Rome.' Then he folded his large hands over his broad stomach and went to sleep.
I must have drifted off myself. At any rate, the next thing I remember is a hand on my shoulder and a voice hissing in my ear that there were men on the bridge. Straining my eyes into the darkness, I heard the sound of the horses' hoofs before I could make out the shapes of the riders – five, ten men or more, crossing at a leisurely pace. 'This is it!' whispered Flaccus, jamming on his helmet, and with surprising speed for a man of his girth, he jumped down the stairs three at a time and ran out on to the road. As I ran after him I heard whistles and a trumpet blaring, and legionaries with drawn swords and some with torches began appearing from all directions and surging on to the bridge. The oncoming horses shied and stopped. A man yelled out that they must fight their way through. He spurred his horse and charged our line, heading straight for the spot where I was standing, slashing right and left with his sword. Someone next to me reached out to grab his reins, and to my amazement I saw the outstretched hand cleanly severed and land almost at my feet. Its owner screamed and the rider, realising there were too many to hack his way past, wheeled around and headed back the way he had come. He shouted to the others to follow, and the entire party now attempted to retreat towards Rome. But Pomptinus's men were flooding on to the bridge from the opposite side. We could see their torches and hear their excited cries. All of us ran in pursuit – even I, my fear entirely forgotten in my desire to seize those letters before they could be thrown into the river.
By the time we reached the middle of the bridge, the fighting was almost over. The Gauls, distinctive by their long hair and beards and their wild dress, were throwing down their weapons and dismounting; they must have been expecting an ambush such as this. Soon only the impetuous rider who had tried to break past us was still in his saddle, urging his companions to show some resistance. But it turned out they were slaves, with no stomach for a fight: they knew that even to raise a hand against a Roman citizen would mean crucifixion. One by one they surrendered. Eventually their leader also threw down his bloodied sword, then I saw him bend and hurriedly begin unfastening the straps of his saddlebag, at which I had the rare presence of mind to dart forward and seize the bag. He was young and very strong and almost managed to hurl it into the river, and would have done so had not other willing hands reached up and dragged him off his horse. I guess these men must have been friends of the soldier whose hand he had cut off, for they gave him quite a kicking before Flaccus wearily intervened and told them to stop. He was dragged up by his hair and Pomptinus, who knew him, identified him as Titus Volturcius, a knight from the town of Croton. I meanwhile had his bag in my hand, and I called over a soldier with a torch so that I could search it properly. Inside were six letters, all sealed.
I sent a messenger at once to Cicero to tell him that our mission had borne fruit. Then, once our prisoners had all been bound with their hands behind their backs and roped in a line at the neck – all except the Gauls, who were treated with the respect due to ambassadors – we started back to Rome.
We entered the city just before dawn. A few people were already up. They stopped and gawped at our sinister little procession as we crossed the forum and headed up the hill to Cicero's house. We left the prisoners outside in the street under close guard. Inside, the consul received us flanked by Quintus and Atticus. He listened to the praetors' accounts, thanked them warmly, and then asked to see Volturcius. He was pushed and dragged in, looking bruised and frightened, and immediately launched into some absurd story about being asked by Umbrenus to convey the Gauls out of the city, and at the last moment being given some letters to carry, and not knowing their contents.
'Then why did you put up such a fight on the bridge?' demanded Pomptinus.
'I thought you were highwaymen.'
'Highwaymen in army uniform? Commanded by praetors?'
'Take the villain away,' ordered Cicero, 'and don't bring him back until he's ready to tell the truth.'
After the prisoner had been dragged out, Flaccus said, 'We need to act quickly, before the news is all over Rome.'
'You're right,' agreed Cicero. He asked to see the letters and we examined them together. Two I easily recognised as belonging to the urban praetor, Lentulus Sura: his seal included a portrait of his grandfather, who had been consul a century earlier. The other four we worked out from the names on our lists as probably having come from the young senator Cornelius Cethegus, and the three knights Capito, Statilius and Caeparius. The praetors watched us impatiently.
'Surely there's an easy way to settle this?' said Pomptinus. 'Why don't we just open the letters?'
'That would be tampering with evidence,' replied Cicero, continuing his minute perusal of the letters.
'With respect, Consul,' growled Flaccus, 'we're wasting time.'
I realise now of course that wasting time was precisely Cicero's intention. He knew how awkward his position would be if he had to decide the conspirators' fate. He was giving them a final chance to flee. His preferred solution was still for them to be dealt with by the army in battle. But he could only delay for so long, and eventually he told us to go and fetch them. 'Mind you, I don't want them arrested,' he cautioned. 'Simply tell them the consul would be grateful for an opportunity to clear up a few matters, and ask them to come and see me.'
