The effect was impressive. Eight bolts at a time, no matter how well-placed, hardly drew the attention of the frothing, frenzied barbarians. Two hundred javelins punching through the line was, however, an entirely different matter.
The bodies of the initial targets collapsed to the ground, causing a number of their comrades to trip and fall across them. The front ranks of the Veragri slowed in uncertainty as a fresh line of iron tips appeared over the parapet, awaiting the order.
“Release!”
The second volley of javelins flew forth from the battlements and plunged into the seething ranks of the Veragri. Chaos ensued as many of the ordinary warriors on the front lines attempted to push their way back through the crowd to flee the deadly hail of pila.
“Arm and release spares at will and then prepare for melee!”
The reserves and support staff below the turf and timber defences passed the few remaining cached javelins up to their compatriots on the walls. Baculus watched as roughly every other man received an extra shot and cast it as soon as he could before settling into a defensive position with gladius and shield.
There was an eerie pause as the front line of the Veragri shuffled around, punctuated occasionally by the shot of one of the scorpions as the engineers fired down into the mass. Baculus tensed. Something would happen any moment now. He had known this to be the breaking point of some weaker assaults, but the Veragri had been planning this for a while, knew they outnumbered the Twelfth tremendously, and were slowly becoming aware that the rain of missiles had all but stopped.
“Steady, lads…”
The strange silence, somehow made all the more oppressive by the distant sounds of battle on other fronts, was broken by a stone, flung with amazing accuracy and power by some hidden arm among the barbarian crowd. The missile crested the wooden parapet, catching one of the legionaries square in the forehead with enough force to knock him from the walkway and send him tumbling down the earth slope within. Instantly one of the reserves stepped up and took his place while a capsarius rushed to help the fallen man. All along the wall, helmets sunk a little to meet shields coming up, closing the gap through which a stone could strike.
And then suddenly the Celtic army answered the Roman artillery with a volley of their own. Hundreds of iron darts and sharp rocks began to arc up from the crowd, aimed at the defenders on the wall. Baculus ducked back behind his shield as he watched the projectiles strike home in increasing numbers. Here and there one would manage a lucky blow between the shields, helmets and wooden palisade and the location would be marked with a shriek and a crack of bone. Baculus leaned back in time to see two men topple from the parapet and down the interior slope of the rampart, either unconscious or dead.
A quick glance upward showed that the towers were out of effective enemy missile range, the few shots aimed at them bouncing off the timber or falling short. Over the enemy onslaught, the engineers kept up their steady pace with the scorpions. Another glance at the mass of Veragri confirmed that the artillery were picking off more targets every minute than the Celts could manage with their darts and rocks, but the Twelfth would be unable to withstand the attrition rate for long.
He realised with irritation that even the support staff and reserves were in danger, as missiles that crossed the parapet without striking home were falling among those inside the fort. Something would have to be done soon, or the reserves would end up buried in a pile of rocks.
“Reserves and support staff…” he shouted down inside, attracting the attention of everyone he could. “Gather all the fallen missiles you can and get up into those towers where you can throw them back!”
There was a pause for only a moment, while the more nervous of the men within weighed up the chances of being struck by one of these projectiles while gathering them if he left the safety of his shield. Then the interior of the camp burst into life, men grabbing baskets and sacks and beginning to fill them with darts and stones.
Baculus turned back to the enemy, trying to ignore the occasional cry of pain from behind where one of the support staff was caught in the open by a falling stone. The men on the wall had given up hope, if that was an appropriate word, of being able to take on the enemy with swords and had closed up in small pockets with their shields raised, forming mini testudos that effectively protected them from almost any angle.
Baculus was impressed. He knew there were still a few veterans among the men, but that kind of quick thinking was what saved armies. Keeping himself covered as best he could, he watched tensely as bags and baskets were hauled up the towers on ropes that were used for rearming the artillery from the ground. The hail of projectiles was beginning to slow. Soon the enemy would run out of missiles, both purpose-made and hastily-gathered, and the assault would begin in earnest. At that point it would come down to pure numbers. The Roman army was the most effective force the world had known. Gods would tremble before the legions, but the simple fact was that no army, no matter how good, could fight odds like this for long.
Men were now hurrying up the ladders and to the towers. As the primus pilus watched, two were caught mid-climb by stray weapons and thrown clear into the fort’s interior, but more arrived on the raised platforms every moment and, without waiting for the order from a superior, they began to cast the waste projectiles back among the enemy.
Once again, the Celtic lines faltered under this fresh barrage and slowly the missile fire from both sides diminished and tailed off to the occasional lob, while the ‘thunk’ of scorpion fire continued unabated.
“This is it, lads. Break your testudos now and get ready. I don’t want to see any of you fighting cleanly or being fair. If you see Gallic flesh, stab it, hack it, kick it or bite it. I don’t care what you do, just keep them off the ramparts.”
There was a trickle of nervous laughter along the palisade as men resumed the traditional stance of the legionary line, shields presented and blades hefted at the ready.
“Remember, we’re eagles, not sparrows! If the Twelfth are destined for Elysium today, we’re going to swim there in a river of barbarian blood!”
A roar ran down the line, triggering a similar response from the enemy thirty yards away and the whole mass suddenly broke into a screaming run, bearing down on the walls with their handful of Roman defenders.
“Here we go!”
“Sun’s coming up!”
“Thank you for stating the bloody obvious, Sep!”
Baculus took the opportunity between exhausted sword thrusts to glance down the line at the source of the banter. Once again it reminded him of a truly veteran unit, where even hard pressed and in constant bloody danger, the troops could find something to laugh at. Off down the wide valley, past the pillars of smoke and the smouldering remains of the native settlement, the first glimmers of morning were showing between the mountainous spurs. A welcome sight, even in the circumstances.
His attention was drawn back to the present situation as one of the barbarians still seething below the parapet threw himself up to the top, hooking an arm over the palisade while trying to swing wildly with the sword in the other. The situation, grave at the onset, was becoming more and more perilous all the time. The centuries defending this wall had suffered almost a fifty per cent casualty rate and, though they had only ever lost control of small sections of rampart very briefly before regaining them, the incursions were becoming more frequent and harder to repel. The end was close.
