In the lull that followed I held a conference with my staff; the wounded were taken to the rear where the waggons stood waiting, and the ranks reformed themselves. Groups of our soldiers went out to recover all the weapons that lay within three hundred yards of our position, and to kill the enemy wounded who lay upon the ground. The men were allowed to fall out, section by section, to eat and drink; the various units re-grouped and the gaps in the ranks closed up. Archers ran up with bundles of fresh arrows, while centurions cried out for more spears and javelins.
A little before midday the enemy began to mass again along the edge of their shattered palisade but, as before, they made no move to come out. To encourage them I had the advance sounded and moved my whole battle line forward three hundred yards. Then I pushed out a line of archers and when they were within range ordered them to open fire. “Watch the wind,” I cried, for I could see the arrows fading to the left as they dropped towards the palisade. The ballistae opened fire and the sky was filled with fireballs. Soon the whole length of the palisade, for half a mile, was covered with points of flame and a pall of smoke hung over the camp as the scrub caught fire. Had the wind been in the right direction we could have smoked them out, but it was blowing gently from the southwest. After half an hour they could stand it no longer; and I could see the sun flicker on the points of swords and spears as, suddenly, a great mass of men moved out of the smoke towards us at a fast walk. Their line extended from the river to well past our left flank and must have been twenty deep at least. In front, with their standards beside them, were the war chiefs of the tribes and, as they came closer, I could recognise Respendial, Hermeric, Gunderic and Sunno, who had succeeded Rando as king of the Alemanni. There must have been twenty-five thousand men on the move and I knew that we could not hold them once they closed the fight; they would destroy us by sheer weight of numbers.
To Fabianus I said quickly, “When the artillery cease fire they are to withdraw immediately back to our last camp. Call up the mules now.” The ships of our tiny fleet were firing steadily in their efforts to break up the advance, but though they did great damage the enemy still came on at the same steady pace. The skirmishing archers were falling back now, each man being covered in turn by the next until, out of range, they took to their heels and ran for the right and left of our centre. My left flank swung round slightly to face the overlap of the enemy right, and then, fifty yards from our motionless front ranks, the barbarians rushed us. I gave the order to fire and the ranks hurled their javelins while the archers flicked arrow after arrow into the mass before them. The enemy front suddenly became a line of huddled dead that mounted, in another moment, into a rising wall of bodies. As the lines crashed together the trumpet sounded twice and Quintus, at the head of his cavalry, fell upon their right flank with two thousand horse. Had we had more men we could have made of it another Adrianopolis. Trapped between the cavalry and the river they would have been hemmed in, forced to fight and die upon their feet until the collapse of the next warrior enabled each man in turn to fall where he stood. But we had not enough men and our success could be only limited. The shock of the cavalry charge broke up the impetus of their attack. They fell back and, in falling back, were forced to turn to face their new enemy. Ridden round by our horsemen, they closed up and fought back stubbornly. Quintus kept his cavalry under an iron control and the discipline he had installed into his commanders showed its worth. Squadrons charged, withdrew, reformed and charged again in hard tight formations so that it was difficult for the enemy to surround and pull individual riders down. For ninety minutes we held them and it was they who fought on the defensive, retreating slowly in a gigantic curve towards the river, pressed inwards the whole time by our cavalry whom they could not contain.
From where I sat upon my horse I could see the whole terrible scene quite clearly. I called up Marcomir’s Franks to support the centre, sent my light cohort out to the left to steady the hard pressed wing, and then rode up and down the line shouting encouragement. For a few brief moments I thought we might do it; and win. I threw in my bodyguard in a desperate effort to drive a wedge through their centre; the charge smashed home and then ground to a halt, checked by the sheer weight of numbers. The air was thick with dust; and the screams of horses, the cries of the wounded and the yells of the living made the giving of orders almost impossible. Very slowly the enemy began to give ground; but they did not break and their retreat was stubbornly ordered, as they withdrew sullenly towards their camp.
I sounded the advance, but my men were too exhausted to obey me. They stood exactly where they had been when the enemy disengaged, in groups and lines, leaning upon their swords; the wounded sinking to the ground; all too tired to follow up their partial success. The horses were blown and stood with bowed heads, sweating profusely, their riders slumped in the saddle, or toppling sideways as their aching muscles relaxed and the pain of their wounds became too much for them. They were quite unfit for another charge. A handful of skirmishers harassed the retreating enemy with bows and javelins; but that was all. A trumpeter blew the retreat and, with my bodyguard holding the field, the cohorts withdrew slowly towards the escarpment and the safety of their camp. The battle had been a draw.
Later that day the barbarians came out from their camp in small parties to collect their dead and wounded, and that night we saw the flames crackle and smelt the smoke of the funeral pyres as they cremated their dead.
The following morning I sent the wounded on ahead, in waggons, towards the safety of the bridge and Bingium. While the men rested, we checked our losses, sent patrols back to the battlefield to collect all the weapons and armour they could, and reformed units.
