‘Push them back!’ Cato roared, edging his mount forward, pressing up against the riderless horse and forcing it aside. A Nubian passed in front of him, out of sword reach, and Cato stabbed his mount in the rump instead. The horse let out a shrill cry and kicked back, narrowly missing Cato’s leg, but striking the flank of his mount so hard that Cato heard a rib snap beneath the glossy hide. Abruptly both animals reared up, the Nubian thrown back into Cato’s side as he threw his weight forward and clung on tightly to the reins to stay in his saddle. The Nubian’s flailing hand caught Cato’s tunic above his knee and the fingers clenched. Cato felt himself shift to the side and the terrifying prospect of falling to the ground and being trampled seized him. He cursed the man through gritted teeth and then swung his sword arm over and tried to cut at the hand. But the gap was too cramped to get a swing and the edge pressed into the flesh and did not cut through. Cato desperately started a savage sawing movement in the space that he had and the Nubian howled and a moment later was forced to release his grip and fell beneath Cato’s horse where his panicked cry was brutally cut short.

Looking up, Cato saw through the haze of dust that the rearmost ranks of the Nubian cavalry were falling back, away from the arrows that rained down mercilessly. The fear swiftly spread through the enemy and as the last of them turned their mounts and galloped off, Cato looked down the battle line. The auxiliaries stared after the Nubians in silence for a moment, too stupefied by the blood rushing through their veins to realise that they had beaten the enemy off. Then Prefect Herophilus thrust his bloodied blade up and let out a roar of triumph, instantly taken up by the rest of his men as they watched the enemy flee. Bodies of men and horses, many still living, lay scattered across the ground amid the angled shafts of arrows.

As the cheers began to die away, Cato was aware of the sound of fighting from the other flank where the enemy had made another attack in an effort to break the Roman cavalry. Cato squinted to make out the details. It seemed that the Alexandrian cavalry unit was holding its own well enough and on the left flank, the archers and bolt throwers were taking their deadly toll.

Cato sheathed his sword and walked his horse over to Herophilus. ‘Well done! That’s fine work by your men. Get them re-formed and ready for the next charge.’

‘Yes, sir!’
