Quintus scrabbled at the stone work. “Can you read this? It’s the Thirtieth, I think. Only the last ten is missing.”
“Yes, look at the emblem. They were raised by Domitian and were still here in the time of Hadrian. A detachment fought alongside us in Italia. Do you remember? By the gods, that seems a long time ago.”
Marcomir said, “It is a place of ghosts.”
“It was not defended to the end,” I said. “It was just abandoned.”
“That was in the time of Gallienus,” said Quintus. “My father told me about it. The cohorts were in forts, seven miles apart, with these posts every half mile in between.”
“And now—nothing.”
We descended the ladders and walked back to where our horses cropped the grass. I looked at the clearing and at the mound of earth, stretching away into the distance. I said, “Once, you could walk along that under the protection of Roman spears. And if you walked far enough you would travel through eight provinces until you reached Scythia and a great sea.”
Quintus said, “I should like to have done that. It would have been a fine thing to walk across the roof of the empire.”
We looked at each other and there was the same thought in both our minds.
Marcomir said, “Then, you were the lords of the world. But now. . . .” He did not end the sentence. He did not need to.
At the edge of the clearing I turned to look back but the square tower was almost hidden now by the driving rain. It was as though even the gods had pity enough to weep for our fallen greatness.
A mile from Moguntiacum we reached the furthest of the out-posts that I had stationed on the east bank. When I had finished inspecting the men and their weapons I spoke privately to the optio in charge. “What is the matter?” I said. “You look as though you had seen a ghost.”
He said, his face tense beneath its leathery tan, “I will show you, general. I have already sent a message across the river.”
We walked as he directed. Two hundred yards from the post I could see an object standing above the ground. As we came closer I could see what it was: the decapitated head of a horse, fixed upon a pole. I looked at the dried blood upon the nostrils, the human hand held between the yellowed teeth and the glazed eyes that crawled with flies. “What does it mean?”
Marcomir said, “It is the common way to insult an enemy in these parts. You may expect trouble from now on. I will warn my people.”
Two nights later I was woken by a disturbance and the camp guard commander was at my door, reporting that a small boat had been seen close to the shore, north of the town. The two men in it had been killed with javelins but the guards’ efforts to catch the boat had failed. It had drifted downstream in the darkness.
“I do not know what they were trying to do, sir, unless making contact with a spy in the town,” he said. I nodded and went back to bed. Long ago I had learned not to worry about small problems that I could not solve. It was as well, for in the morning the puzzle solved itself. I looked at the dead man lying on the bank, close to the point where the guard had intercepted the boat—and I recognised him. “They brought him back to show that they had caught him,” I said. “He was a Frank I sent to spy out the camp of Rando some weeks ago. They were not kind to him, were they, Quintus? Pity. Now we shall never know what he learned.”
The work of preparation and its problems continued. Complaints from quartermasters about a shortage of boots and rations; queries from armourers concerning war heads for arrows and suitable canisters in which to hold the preparation for liquid fire; difficulties over the stabling of spare horses; requests from cohort commanders whom I visited to advise on tactics to meet this eventuality or that; discussions to simplify our signal system; auxiliaries to be commended for their efficiency; and everyone to be encouraged; everyone to be made to believe that with their aid I could achieve the impossible. The days were never long enough, and though I worked my officers hard and delegated my authority as much as possible, both Quintus and I began to feel the strain. We woke tired in the mornings and we went to bed at night to sleep as though we were already dead.
Often I had dreams and I stood again on that beach with Julian, knowing every line on that tired, bitter face, creased with the lines of middle-age; and hearing again the tired, bitter words that he had spoken. It is I who shiver now . . . what happened to my high-priest’s daughter? . . . . they believed I was a god. . . .
Did he know or did he guess that exile was the punishment that Fullofaudes had intended for him? I often wondered.

JULIUS OPTATUS SAID patiently, “I am sorry to trouble you again, sir, but the supplies for this month are overdue. We are short of fodder for the horses; the remounts we were promised haven’t arrived, and General Veronius keeps pressing me to do something.”
I looked at the documents in his hand. “What else?”
“There’s quite a lot, sir.”
“Go on.”
