For a moment he was clear; Gaius tugged his spatha from its sheath and straightened. He could see now that the chariots, having failed to break through the Roman lines, were becoming entangled within them. A chariot lurched towards him on the uneven ground; wood crunched as a wheel hit a boulder and it slewed round. He saw the driver hacking at the traces. Whinnying wildly, the horses sprang free, joining the others that careered in panic through the battle, knocking down friend and foe.
Battle was fairly joined now; the slopes of Graupius seethed with knots of struggling men, clumping and unraveling and knotting again in a constantly shifting tapestry. But it appeared to Gaius that little by little, the Romans were gaining ground.
Then a spear seemed to thrust up from the ground before him with a snarling face behind it; his pony reared as he whacked the shaft aside with his sword and slashed downward. Red covered the blue designs as the blade bit, then the horse leaped forward and the face was gone, and Gaius was slashing and guarding with no time for thinking at all.
When he next had a moment to focus, they were well up the mountain. From the left he heard shouting; the Caledonians who had been watching the battle from the summit were now descending, leaping down the slope with appalling swiftness to take the Romans from the rear. Could Agricola see it? Gaius heard once more the bray of the Roman trumpets, and grinned as the four wings of cavalry the General had been reserving swung into action at last. They outflanked the Britons and hammered them against the anvil of the infantry; then the true slaughter began.
Calgacus’s force had lost all cohesion. Some men were still fighting, others tried to flee, but the Romans were everywhere, killing or making prisoners only to slay them in turn as yet more enemy warriors came their way. Gaius saw a gleam of white near by and spotted Agricola in the middle of the battle with only two tribunes and a couple of legionaries to guard him. He turned his mount that way.
As he neared them, one of the tribunes shouted. Three Britons, their finery soaked in blood and armed only with knives and stones, were charging. Gaius kicked the pony hard. He swung and his blade tore a crimson gash through the chest of the first man. Then his horse stumbled on something soft; Gaius felt himself falling, released his shield and wrenched himself free as the animal went down. He saw a knife flash and felt pain sear his thigh; the horse tried to struggle to its feet and the knife flared again, sinking into its neck; the animal jerked and went back down.
Gaius got up on one elbow, sank his own dagger into the Briton’s chest and then used it to cut the throat of the dying horse. Then, grimacing as his thigh began to throb, he started to get up, searching around for his shield and sword.
“You all right, lad?” Agricola was looking down at him.
“Yes, sir!” he started to salute, realized that the dagger was still in his hand, and sheathed it again.
“Fall in, then,” said the General, “we still have work to do.”
“Yes —” Gaius began, but Agricola was already turning away to give someone else an order. One of the tribunes helped him to his feet, and he tried to catch his breath.
Blood had dyed the bracken at his feet a deeper crimson. The field seemed a mass of broken men and weapons, and those enemies left alive were scattering, pursued by the cavalry. The Romans on foot followed more slowly as the Caledonians fled towards the forest on the other side of the mountain. Agricola ordered some of the men to dismount and beat through the wood while the others circled round behind it.
It was at the edge of the wood as dusk was falling that Gaius whirled to face a man who sprang out at them. He swung instinctively, but he was tired and the blade turned in his hand, taking the warrior on the side of the head and bearing him to the ground. He drew his dagger and bent over the man to finish him, and swore as a bloody hand seized his arm. He lost his balance and came down on top of his enemy; the two of them rolled over and over, fighting for possession of the blade.
