When we were back again at Constantinople my mistress found two letters from Belisarius waiting for her that had come by a quicker route. They were written in such simple, elegant language and indicative of such honest ardour that, since this love was not only sanctioned but positively enjoined upon the two of them by Imperial orders, she broke a life-long rule, and committed her own amorous feelings to writing. Many scores of long letters passed between them until his return to her some eighteen months later.
The next phase of the war was a Persian invasion of Roman Armenia; but it was energetically checked by Sittas, Belisarius's former comrade, who was brother-in-law to Theodora. The Roman name being now held in greater respect than formerly, a number of Christian Armenians from the Persian side presently deserted to the Imperial armies. Kobad also lost the revenues of the gold-mine at Pharangium, a town situated in a fruitful but almost inaccessible canyon on the border between the two Armenias; for the chief engineer there elected to put the city and mines under Roman protection. Kobad, with the obstinacy of old age, refused to withdraw his troops from the neighbourhood of Daras, though Justinian sent an embassy to re-open peace negotiations. Each side tried to fix the moral responsibility for the conflict on the other. Kobad told the Roman ambassador that the Persians had done meritoriously in seizing and garrisoning the Caspian Gates, which the Emperor Anastasius had refused to buy from the owner even at a nominal price; since, by doing so, he had protected both the Roman and Persian Empires from barbarian invasion. The garrison was costly to maintain, and Justinian should, in justice, either pay a half-share of the expenses or, if he preferred, send a detachment of Roman troops there sufficient to permit half the Persian garrison to withdraw in their favour.
Then King and Ambassador discussed the breach of an ancient treaty regarding frontier fortifications. The Roman fortification of Daras, Kobad pointed out, had made it strategically necessary for the Persians to keep a strong frontier force at Nisibis; and this again was an unfair tax on his country's resources, and was one injustice too many for him to accept. He now offered Justinian three alternatives to choose from: contributing to the defence of the Caspian Gates, dismantling the fortifications of Daras, renewing war. The ambassador understood the King to mean that a money tribute, speciously disguised as a contribution to common defence against the barbarian menace, would end the conflict.
Justinian could not yet decide whether or not to offer a money tribute. While he deliberated, Kobad was visited by the King of the Saracens, his ally, with a plan for a severe blow at the Romans. The Saracen was a tall, lean, vigorous old man, whose Court was at Hira in the desert, and who for fifty years had been raiding Roman territory between the Egyptian and Mesopotamian borders. He would appear suddenly from the wilderness with a force of a few hundred horsemen, plunder, burn, massacre, take prisoners – by the thousand sometimes – and then disappear again as suddenly as he came. Several punitive expeditions had been made against him, but all had been unsuccessful; for the art of desert warfare is only understood by those born to the desert. He had cut off and captured two strong Roman columns operating against him and held their officers to ransom.
This old king, then, suggested to Kobad that instead of campaigning as usual among the head-waters of Euphrates and Tigris, where the Romans had a number of walled cities to fall back upon if attacked, he should take a southerly route, which no Persian Army had ever taken before, following the Euphrates. At the point where the river-course turns from west to north he should strike across the Syrian desert. For here, beyond the desert, the Romans, trusting to the natural defences of waterless sand and rock, had built only few fortifications, and these were manned by no troops worth the name. If vigorously attacked, Antioch would fall into their hands without a struggle, because – he was justified in this comment – Antioch is the most unserious city in the entire East, the inhabitants having only four interests, namely wine, sex, Hippodrome politics, and religious argument. (Trade is not an interest, but a disagreeable necessity to which they submit in order to keep themselves in funds for the active prosecution of these four exciting interests.) What a magnificent city to plunder! And the raiders could return safely with their spoils long before any rescue could arrive from Roman Mesopotamia.
Kobad was interested but sceptical. If no Persian Army in the past had found this approach feasible, in what way had conditions altered to make it so? How would an army, unaccustomed to temporary starvation and thirst, maintain itself in the parched, pastureless desert?
