Justinian, on reading the reports that came to him, decided that the Commander of the Armies in the East had made an error of judgement in sending Belisarius inadequate and ill-led forces, and that Belisarius was the only soldier who had not tarnished his reputation. He therefore dismissed this Commander of the Armies and appointed in his place Belisarius, whose age at that time was only twenty-eight. Justinian also sent out to the frontier the Master of the Offices, one of his chief ministers, whose duties included the supervision of posts, communications, and arsenals throughout the Eastern Empire, and foreign embassies abroad. This Master of Offices was charged with resuming peace-negotiations with the Persians but protracting them as long as possible, thus giving Belisarius time to put Daras and the frontier generally into a posture of defence. Belisarius took advantage of this truce to make a tour of inspection of the frontier, strengthening fortifications, raising and drilling troops, collecting military stores. It was hoped that a renewal of hostilities might be avoided, because Kobad at the age of seventy-five seemed likely to prefer a tranquil old age to the anxieties of a major war. But this was not to be.
Belisarius, who had succeeded in getting together an army of 25,000 men (of whom, however, he could not count on more than 3,000 to show hardihood, cither in attack or defence) soon heard that a well-trained army of 40,000 men under the command of the Persian generalissimo Firouz was marching against him. Then came a Persian messenger with an arrogant message for Belisarius: 'Firouz of the Golden Fillet spends tomorrow night in the City of Daras. Let a bath be prepared for him.'
To which Belisarius replied with the amiable wit which became his handsome person: ' Belisarius of the Steel Casque assures the Persian Generalissimo that the sweating chamber and the cold douche will both be ready for him.'
The person who felt most insulted by Firouz's message, strangely enough, was not Belisarius but a bath-attendant. He was that same Andreas who had been Belisarius's satchel-slave. Andreas had been given his freedom sonic years before at Constantinople, and had been employed as instructor at a wrestling-school near the University until he came East to rejoin Belisarius at Daras.
Belisarius's tactical problem now was the familiar table-problem of the poor country inn-keeper who is forced to provide a banquet at short notice for a number of hungry guests: namely, how to make a little go a long way. Like the inn-keeper, he knew that his little was of inferior quality, and like the inn-keeper, too, he solved his problem by a carefully laid table and a brave smile and by putting the best food and wine foremost, keeping the coarser food and the worse wine in reserve. The coarser food and the worse wine were his infantry, half of whom were recent recruits. He had decided, because of the short time at his disposal, not to attempt to train these recruits in more than one art: he therefore chose to make archers of them. He provided them with long, stiff bows and regulated their pay according to their gradually increasing skill with these weapons; but it was only what he called 'random shooting'. He demanded no more than that each man should be able to send his whole quiverful of forty arrows a distance of at least a hundred yards, keeping them within an angle of not more than ten degrees. Against a massed enemy this would be sufficient aim. He had already manufactured an enormous quantity of arrows, and continued to keep his artificers busy at forging more arrow-heads and trimming and feathering more shafts. The trained infantry he also perfected in a single art, namely the defence of a narrow bridge against cavalry or infantry charges; he found them all chain-armour and spears of varying lengths, drilling them in the phalanx-formation used by Alexander, the front of which bristled with spears like an Indian porcupine. The half-trained infantry he practised in javelin-throwing.
The better food and wine, in this metaphor of the poor inn-keepir, were his cavalry. He had temporarily broken up his Household cuirassiers into six parties, which he sent as model troops to the six regular squadrons of heavy cavalry, to set them a standard of training for emulation: he did not represent them as instructors, only as challengers in the arts of shooting and tilting and rapid manoeuvre — but instructors they became. He also had with him two light-cavalry squadrons, of Massagetic Huns from beyond Bokhara and Samarkand, old enemies of Persia. And half a squadron of Herulian Huns whose summer quarters were in the Crimea; they were archers, with a quick rate of fire, and for fighting at close quarters they carried lances and Broadswords. They wore buff-coats, with light metal plates sewn on them, but no other body armour. (Light cavalry is essential for outpost work on the frontier, Belisarius held, but must be supported by a strong striking force of heavy cavalry garrisoned not far away. The Empire was poor in light cavalry; as might be deduced from the fact that both the Herulian and Massagetic Huns live many hundreds of miles from the Roman border.)
Belisarius went out in front of Daras, just beyond the parade-ground which borders the fosse. He staked out a crooked system of trenches to be dug, six feet deep and twelve feet wide, with a narrow bridge at every hundred paces. The system, viewed from the battlements of the fortress, was like a drawing of a square-crowned, wide-brimmed hat, with the top of the crown resting on the farther edge of the parade-ground. Since this was to be a battle of the Persians' own choosing, and since their object was the capture and dismantling of Daras, Belisarius could afford to remain on the defensive; and indeed to have taken the offensive with troops like his would have been most unwise.
Around the three sides of the open central square, or re-entrant, of the trench-system, Belisarius stationed his infantry, with phalanxes of spearmen guarding the bridges, supported by the javelin men, and with the archers lining the length of trench between. The trench was set with pointed stakes along its whole extent and was too broad to be leaped by cavalry. Forward on the wings, behind the advanced trenches (the brim of the hat), he stationed heavy cavalry. The bridges across the trenches were somewhat wider here, to allow for more rapid movement. As a connecting link between centre and wings, 600 Massagetic Huns were stationed inside each comer of the re-entrant, ready to bring a cross-fire of arrows against the enemy should they advance against the infantry, or to go to the help of cither cavalry wing that might be involved in difficulties. In reserve he kept his own Household Cavalry, now reunited, and the Herulian Huns.
These were his dispositions. Everyone approved them at the council of war at which they were explained. The men were in excellent In-all in spite of the very hot July weather: the expected outbreak of dysentery and other hot-weather sicknesses, almost inevitable at Daras at this time of year, had not taken place. The fact was that Belisarius had issued most strict regulations about the mixing of all drinking-water with sour wine to purify it; and about the cleanliness of latrines and field kitchens; and especially about allowing no harbourage for flies- for he said that Beelzebub, the Lord of Flies, was the chief devil of destruction and that where there were flies, there was sickness. Moreover, all military exercises had been carried out in the early mornings before the sun was strong; after which the men slept until noon. In the evenings he had sent them out on night-marches to keep them in good physical condition, or employed them in digging. Beli-sarius never allowed his men to stand idle. They were now in proper fighting spirit, and had the greatest confidence in their young commander.
At sunrise on the day after Firouz's messenger had come, the lookout on the battlements reported clouds of dust rising along the road from Harmodius, a village near Mygdon in the direction of Nisibis. Soon the Persian columns came in sight, forming up in close order out of range of the Roman bows; with infantry, concealed behind enormous oval shields, in the centre, and cavalry on either flank. It was estimated that their army numbered 40,000 men. But Belisarius's comment was: 'There are few generals capable of controlling forty thousand men in battle. Firouz no doubt would feel easier in mind if the armies were more equal in numbers.'
