History may forget me as a physician, Caesarius, it may even deride me as an encyclopedist; but as a king-maker, I rank among the best.'
II
Of our march, Brother, I have hardly a word to say, for although we and Jovinus' unit constituted the first hostile armies in generations to pass those ancient Roman cobbled roads through the Alps, to Italy and beyond, we met not a single enemy, none of the ambushes and other obstructions we had anticipated, not so much as a stone thrown by a mischievous boy. You may doubt whether such a short description as the one that follows can adequately cover the story of a secret march of nearly eight hundred miles through hostile territory. Yet I truly cannot recall any events I have omitted that might swell this brief recounting to something more substantial. The troops were force-marched twenty miles a day and more, and the speed of the army's sweep and its surprise tactics created the intended effect, without need for us to strike a single blow. Panic ensued in the lands around us. Days before our arrival word had already been spread by Constantius' scouts, and cities were emptied, their garrisons scattered or force-marched farther south and east. The praetorian prefect for Italy, the most powerful civil official in the province, fled before Jovinus, taking with him the prefect of Illyricum as well. The speed and smoothness of our approach to the Danube was breathtaking, almost worrisome in its lack of impediment, as if Constantius were reserving his forces for some massive attack upon our arrival.
Smooth and speedy, I say, except for my own duties. As master of the couriers I worked day and night coordinating the messages and dispatches between Jovinus and Nevitta, as well as all the myriad details unrelated to official correspondence with the three armies — arranging advance supplies, resolving administrative issues back in Gaul, and promotions and transfers within the legions, but in one area, the most important of my duties, I failed miserably, and this I was sick about. For during the long, uneventful weeks of our march, not a single contact did I make with Julian — not a single order received from him, not a single progress report successfully sent to him. Every one of my post-riders returned to me weeks after having been sent off, unable or unwilling to enter far into the Black Forest in search of him, stymied in their attempts to obtain news of his whereabouts. The forest is big, I mused, huge — but large enough to swallow an Emperor and three thousand men without a trace?
At first I attributed the loss of Julian simply to my post-riders' incompetence, or to mine in giving them faulty instructions or incentive. Week after week of silence from one's commander, however, gives one pause. Nevitta was outraged, terrified at having committed his life and promising career to the insane venture of rebelling against Constantius with a meager force of ten thousand men, and with his leader consumed by wild beasts or tribes in the wilderness. All we could do, I told him, was to arrive at Sirmium ourselves to wait for him, pray, and hope for the best.
Limping sore-footed into Sirmium on the appointed day, with Jovinus' troops still two weeks' march behind us in their arrival, we were astonished to see the city gates wide open in welcome. Cheers erupted from the town walls and battlements as the population gathered to throw flowers down on our weary troops. We were met at the entry by fresh and rested Gallic troops, who escorted us to the central forum, where we were greeted smilingly by — who else? — Julian, who had, unbelievably, arrived two days earlier, having outrun every single one of my messengers along the way with his three thousand cavalry, and arranged the welcoming party for us upon our arrival. Our jaws dropped upon seeing him thus, and I wager that the only person more surprised than we was one Lucillianus, the Roman commander in charge of Pannonia before our arrival, whose story is worth a slight diversion to make up for the lack of events to recount to you of our own march.
Count Lucillianus was a veteran soldier who had fought bravely against the Persians and had recently been promoted to his present position. Several days before, he had received vague intelligence of Julian's approach, which, to give the man credit, was more than I myself had been able to arrange. Thinking, however, that he had several days or a week by which to arrange his defenses successfully and thereby garner great favor from Constantius, he went to bed that night content in the thought of his upcoming victory. He slept soundly until he was rudely awakened in the dim hours of the morning by the point of a sword against his throat and a crowd of evilly grinning men gathered about his bed. No answer was given to his shouts of protest, but he was bound, gagged, placed on the first available beast they were able to find in the barracks outside, which happened to be a donkey, and driven like a wretched prisoner past his own personal guard, themselves gagged and trussed like chickens, to the military quarters in the center of town. Upon being frog-marched into his office, Lucillian found Julian calmly sitting in his own chair, reading Marcus Aurelius.
It seemed that the Caesar had encountered an unexpected bit of luck in his journey. They say that as a harsh taskmaster, Alexander the Great was unexcelled — his idea of breakfast was a long march, and of supper, a light breakfast. Julian was typically somewhat more generous with his own breakfast, treating himself to an entire glass of water, when available, but in all other respects he followed Alexander's example in driving his troops and their horses mercilessly in their nonstop charge through the forest, fortunately having not met with any unicorns or other such creatures that might have slowed their progress. When they gained the Danube they captured a sufficient quantity of small boats to transport his entire force straight down the current, which was fast that fall, and which they augmented even further by steady rowing. The superhuman labors of his men at the oars, as well as a week of favorable winds, had carried his fleet over seven hundred miles in a mere eleven days. Landing nineteen miles above Sirmium, Julian had taken advantage of the moonless night to thunder his troops straight to the city in a matter of two hours, silently overwhelming the guards before they had even known they were under attack, and capturing the commander.
Lucillianus nearly died of fright, but upon recognizing the Caesar, who was wearing the imperial purple and who promised him clemency in return for an oath of fealty, he decided to make the best of his situation, and even attempted to show his gratitude for the reprieve by offering some timely advice.
'It is rash and reckless of you, Emperor, to invade another's territory with so few men,' the Count proffered cautiously.
Julian answered with a bitter smile. 'Save your wise words for Constantius, soldier. You may kiss the imperial purple not because I need your advice, but to calm your own nerves.'
Lucillianus did, immediately swore fealty to his new Emperor, and was given a position of command in Julian's legions.

In Sirmium, Julian spent but three days, for time was of the essence and momentum was on his side. Thus far he had moved with his entire army faster than Constantius' couriers and spies would be able to report his movements back. Conversely the Emperor, unaware of the speed of Julian's march, had been content to lumber slowly along on his return from Syria, stopping in each major city along the way to receive the acclamations of his subjects.
Julian paused only long enough to restock his supplies, stage a chariot race as a reward to the city for the favorable reception its people had given him upon his arrival, and secure the outlying garrisons. Reinforced now by Nevitta's troops, he resumed his rapid march on Constantinople. Advancing down the Danube, he entered Moesia, which was bordered on the south by Thrace. Thrace, in turn, was bounded on its southern coast by the Sea of Marmara, on which Constantinople, his goal, was located. He had therefore already accomplished almost half his journey without the loss of a single soldier or the death of a single Roman citizen.
The road ahead of him, however, was by far the most hazardous, for the region of Thrace was well fortified with strongly walled cities such as Philippopolis and Adrianopolis. These would have to be taken and passed before the capital could be reached, and the sentiments of the garrisons and citizens of those cities were anything but certain. What is more, like an eel trap with its spikes of sharpened reeds pointing inward to prevent its quarry from escaping once it had entered to take the bait, Thrace was an easy region to access, but almost impossible from which to withdraw under hostile conditions. The approach was a vast range of mountains running from east to west, with only a single pass across it, through the valley of Soucis. Although the valley was an easy march to
