Shock and terror would clear them off quickly enough. And then speed of retreat would be everything.
The eighty men came screaming and yelling up through the reedbeds, muddy and plastered with weed, swords whirling. The women took one horrified look at these river-demons, snatched their infants down from the wagons and fled. The superventores were at the wagons in an instant, kneeling down behind the solid wooden wheels emptying their backpacks, plastering the dry old wooden wheels with a special mix of naptha, sulphur and highly refined oil on wads of fresh lambs’ wool, sticky and murderously flammable. Right across the rear of the Hun lines the wagons stretched away, piled high with the loot of half the civilised world. There might have been a hundred, no, three or four hundred – they couldn’t possibly damage them all. But by the time word got to the nearest Hun warriors, sitting their horses in the rear battle-lines, the Batavians had fixed up over thirty wagons.
A couple of hundred horse-warriors came galloping furiously back across the grass towards them.
The commander of the superventores knelt, flipped open his tinderbox and flicked the wheel.
‘Sir, we’re in range!’
The first arrows hit the ground nearby. A junior lieutenant held out a wooden staff topped with a blob of pitch and the commander lit it.
‘Now run!’ he roared. ‘The rest of you – to the river!’
The main body sprinted for the water, crouching low, while the lieutenant dashed along the line of wagons with the flaming torch extended. Every time it brushed against a treated wheel, the wagon exploded into flames like a bone-dry hayrick.
The Huns were bewildered and indecisive, some making towards the burning wagons intending to extinguish them and save the loot, though God only knew how. That moment of confusion was the lieutenant’s chance of escape, and he took it, sprinting towards the river, dashing beneath a low-hanging alder for cover even as arrows sliced through the leaves around him, and diving headlong into the river. Horsemen arrived on the bank above, howling with fury, their horses champing, tossing their brutish heads, fighting against entering such a fast-moving current when unable to see the bottom. The riders drew back their bows and arrows slapped into the water but instantly lost trajectory, flattening out across the surface like skimmed pebbles or spinning round to face the powerful current. In any case, the Batavians were already down in the murky depths, lungs forcibly emptied, navigating only by the feel of the current dragging them back to safety, swimming like tritons with grins across their water-stretched faces.
As Aetius well knew, such flamboyant tactics had absolutely no effect on the material progress of the battle, but they could do wonders for morale. His lines cheered wildly as the black smoke billowed up into the air behind the Hun army, and they saw the Hunnish leader himself, fearsome Attila, galloping furiously back to view the damage.
‘An ostentatious little jape,’ muttered Aetus, ‘but a useful one.’
Tatullus grinned. ‘What’s he wasting his time for? He needs to get on with it.’ He jerked his head right.
Aetius nodded. The sun was indeed, as usual, coming round. With every delay, the Huns would have to fight facing more and more directly into it.
The commander of the superventores reappeared, still at the run. Well, special forces were expected to be able to cover forty miles in a day with sixty-pound packs on their backs. This was a nice day out for them.
He saluted. ‘Job done, sir.’
‘Casualties?’
‘None, sir, apart from one novice who slipped coming out of the river and bloodied his pug. Getting bandaged up right now.’
Aetius grinned. ‘Good man. To the rearguard now. There’ll be more work for you later.’
‘Sir.’
It was late morning, and still nothing. Attila’s delaying tactics were wearisome to the Romans, but they would test his own, undisciplined warriors’ patience to the limit. Sooner or later they were going to have to charge. That mile between them would tire them, especially with their horses, poorly fed for these past weeks and months. And then they would hit the earthed-up pikes of the Alans and, behind them, the Roman legionaries. That was what Aetius wanted. As for the coming arrow-storm, he had two ways to deal with that.
Meanwhile the two armies stood motionless, and the sun kept coming round. Tube-like dracones, wind-socks, droned in the wind. The Hun horses stamped restively. Occasionally there were sorties from their lines, jeered at and sharply rebuffed, the horsemen retreating in disorder. Then as the air warmed a light southerly breeze blew up.
Aetius looked sharply at his centurion.
Tatullus produced a small white feather, raised it above his head and let go. It twirled briefly, then drifted steadily towards the Hun lines.
The centurion looked around, scanned the horizon. ‘A calm summer’s day. June. Gaul. A few clouds low in the west.’ He grinned at Aetius. ‘Yep. I reckon.’
Aetius nodded, and Tatullus roared over the front rank, ‘Fire the smokescreen!’
Immediately a great sheet of flame coursed along before the Roman line, and then quickly burned down to thick smoke. The auxiliaries ran between the files and poured on oil and dead branches, sacks of leaves, commandeered haybales and, best of all, thick green summer grass. The pall of smoke thickened, rose into the air forty, fifty feet, and drifted always north towards the Hun lines. In a few minutes they’d be blinded by it. And, when they came through it, by the sun.
Sweaty hands tightened around butted pikes, men crouched low. Some used corners of grimy neckerchiefs to wipe the sweat trickling down their foreheads and stinging their eyes, then quickly returned their hands to their pikes. The sweat would have to drip, because they all felt it now. The earth was rumbling. Beyond the smoke, the Huns were charging.
The next noise was the distant, muffled strum of the torsion springs of the Lightning Boys’ arrow-firers and sling-machines. Of course. From their position they could see the Huns charging below them. Thank God they held that hill. Then there were the screams of men and horses erupting soprano above the deep rumble of the charge. First blood. Those steel-head bolts were hitting home, horses rolling forward and tripping, the charge running in behind, getting tangled.
The smokescreen had worked. The Huns weren’t firing, not through that thick curtain. They were coming through it.
‘Steady, lads!’ shouted Aetius. ‘Lean all your weight on those pikes, now. Hold the line. Here they come.’
Many of them saw it in slow and dreamlike motion. Out of that drifting, cloudy wall of smoke only thirty or forty yards in front of their pikes, first emerged those big, brutish horses’ heads, and their hooves, and legs, then the whole animals, and riding them the naked savages, spiralling their swords, hatchets and lassos above their shaven, tattooed heads, howling like demons loosed from hell.
They hit the Alans hardest, but not before the Roman legionaries had stood up behind and hurled their javelins from their jointed javelin-throwers in a ferocious volley, so perfectly aimed and timed that perhaps every other front-rank Hunnish horseman was brought down, slowing his comrades behind and tangling them up just where they didn’t want to be. Many flew to the ground and lay uninjured but stunned. Then the Alan lancers broke rank and ran out to butcher them where they lay.
‘Back into line you fools! Hold formation! Pull back now!’
But the Alans lacked the discipline. Seeing what they thought was the impotent chaos of the Huns before them, they acted as headstrong individuals, dropping their pikes and pushing forward, drawing their swords. It was madness. Though a hundred or more Huns had fallen in that first javelin volley, many more were coming on behind, and those who had lost their horses and been stunned in falls were instantly on their feet again, daggers and sharpened chekans in hand. The Alans were surrounded and cut to pieces.
