four lines deep, maintaining themselves in good order, flanked by three thousand horse archers maintaining their own excellent discipline.
Very impressive, but—
The Roman archers in the fortifications—Ghassanid mercenaries, these—were now aiming all their fire at the Mede cavalry attacking the right. They were ignoring, for the moment, the swarm of Persian horse archers in the center who were raining their own arrows on the encampment. Hermogenes, Belisarius noted, was keeping a cool head. Protected by the wall in front of them, his infantry would suffer few casualties from the Persian archers. Meanwhile, their arrows could hamper the advance of the Persian lancers.
Hermogenes had trained his men well, too. The Arab archers ignored the temptation to fire at the lancers themselves. The heavy Persian armor would deflect arrows from their light bows, especially at that range. Instead, the men were aiming at the unprotected legs of the horses. True, the range was long, but Belisarius saw more than a few Persian horses stumble and fall, spilling their riders.
From the hill, a flight of arrows sailed toward the Persian cavalry advancing on the Roman right. But the arrows fell short and the volley ceased almost immediately. Belisarius knew that Maurice had reined in the overenthusiastic cataphracts. The range—firing diagonally across the entire battlefield—was too extreme, even for their powerful bows firing with the wind. Instead, Maurice ordered his cataphracts and the Isaurians to concentrate their fire on the swarm of light horse archers in the center.
Belisarius was delighted. His army was functioning the way a good army should. The archers on the left were protecting the infantry in the center, while they harassed the Persians advancing on the right.
A volley of scorpion darts and onager stones sailed into the Persian heavy cavalry, tearing holes in the ranks. The cavalry began to spread, losing their compact formation.
Good, Phocas, good. But, with this wind, it should be possible—
Yes!
The next artillery volley fell right in the middle of the Persian command group at the rear of the battlefield. The Persian officers hadn't expected artillery fire, and their attention had been completely riveted on the battleground. The missiles arrived as a complete surprise. The carnage was horrendous. Those men or horses struck
