'Get down!'
The Romans dropped behind their shields as the air was filled with the zipping sound of slingshot hurtling towards them. The volley was well aimed and only a handful of shots cracked through the branches overhead. The rest struck the Roman shields in a rattling cacophony of thuds. The bombardment continued remorselessly and Macro had to take the risk of being struck each time he glimpsed round his shield to check the progress of Caratacus' assault wave. The enemy waded steadily across the ford, no longer slowed down by the underwater obstacles. This was no wild charge, and the warriors advanced with deadly intent, not needing the cheap morale boost of a frenzied Celtic rush towards the thin Roman line.
The slingshot barrage abruptly slackened and then stopped and Macro peered cautiously over the rim of his shield. The enemy was no more than twenty paces away, thigh-deep in foaming spray, and the slingers no longer dared to loose their missiles at the Romans for fear of striking their own men.
'Hit 'em back!' Macro called out. 'Javelins! Slingers, loose!'
There was no parade-ground finesse in the way the legionaries rose up with a shout ripping from each man's throat as those in the rear rank swung their javelin arms back, took a line on the enemy massed before them, and hurled their weapons. On the flanks the Roman slingers let loose a fusillade of shot against the exposed sides of the enemy column, and a few of the warriors fell, sprawling and splashing into the river. The rest recovered quickly from the javelin volley and picked their way through their dead and injured comrades, then closed on the barricade. Macro had hoped that they would rush the last distance in the usual reckless manner but these men were superbly self-controlled, and as some raised their shields towards the waiting Romans their comrades hacked at the tangle of branches and wrenched pieces free.
'Get stuck in!' Macro shouted, grabbing a javelin from the nearest legionary. He flicked it round into an overhand grip and pushed his shield forward, crushing up against the barricade until he was within reach of the enemy. An arm stretched out between the shields and grasped a length of branch. Macro thrust the point of the javelin into the flesh just below the elbow and heard a voice cry out in pain. As he ripped the iron head back there was a sharp clang and heavy impact on his shield boss. He glanced round and saw that a number of the enemy warriors were armed with long, heavy spears and were trying to keep the Romans pinned back, away from the barricade.
'Watch the spears!' Macro yelled.
He searched for a new target and saw eyes glaring at him over the rim of a kite shield. Macro feinted and as the shield shot up he switched the aim and thrust at the man's thigh. At the limit of his reach, the iron tip ripped through the warrior's woven trousers and only grazed the flesh beneath. The centurion grunted in frustration and then carefully stepped back from the barricade, nodding to a legionary in the rear rank to take his place.
Macro looked around at his century. The men were holding their own. The slingers, distanced from the fight along the barricade, had been targeted by the enemy and an unequal exchange was being fought out between the slingers of both sides. The Romans crouched low as they worked their slings up to speed and then rose quickly to release the shot before ducking down again. Their foes enjoyed no such shelter, and Macro noted, with satisfaction, that a number of almost submerged bodies were slowly spiralling downstream from the bloodstained ford. But enough of that, he decided. The slingers' attention was needed elsewhere. He bellowed his next order above the clash and thud of weapons and cries of men.
'Slingers! Target the infantry! The infantry!'
The men on the wings looked towards him, understanding. One fool quickly rose up to have a last shot at the enemy slingers and was instantly struck in the face. His head snapped back and blood sprayed into the air, splattering his comrades on either side. The man collapsed in an inert bundle on the ground. Macro ground his teeth in anger. He had few enough men already, without anyone throwing his life away in such a careless fashion. A soldier's first duty was to his comrades, and he served them best by staying alive and fighting at their side. Such reckless acts of courage or battle rage were criminally selfish, in his view, and he cursed the man. But he was not the first to die. Already there were three other Roman dead: one sprawled on the ground inside the barricade, the others hanging over the tangle of branches, blood pouring from their wounds on to the muddy river bank below.
'Look at that!' a legionary called out nearby, and Macro followed the direction of the man's gaze across the ford. As the slingshot from the Roman flanks lashed into the sides of the enemy column an older warrior was bellowing out orders. The men around him steadily closed up and offered their shields up in an unbroken line to either side and overhead. Macro was astonished by the manoeuvre, which the enemy had clearly adapted from the example of the legions. Now the shot was rattling harmlessly off the shields, protecting the men within.
'Bugger me,' Macro said softly. 'The Britons can be taught.'
A cry of alarm instantly drew his attention back to the struggle along the barricade. At the centre of the line the enemy had succeeded in taking hold of one of the rough-hewn stakes that Macro's men had driven in to hold it all together. Several hands grasped the stake, working it furiously to pull it free, and even as Macro glanced in their direction, the stake lurched a small way towards the enemy, dragging a section of the barricade with it.
'Shit!' Macro hissed, thrusting his way through his men towards the threatened area. 'Stop them! Get those bastards now!'
The legionaries turned their attention on the men grasping the stake, desperately thrusting at their exposed arms. The warriors charged with defending these men were equally determined and shoved forward into the barricade, stabbing the broad iron spearheads at the defenders. The intensity of the struggle was such that both sides fought in teeth-gritting silence, straining with the effort to push the enemy back. Suddenly there came the sharp cracking of wood and with a lurch the stake came free, sending half a dozen of the warriors flying back into the ford. Around them the Britons roared with triumph and pressed forward into the gap.
'Hold them back!' Macro cried out, hurriedly throwing his javelin into the enemy ranks. 'Hold them back!'
He snatched his sword from its scabbard, crouched low and threw his weight behind his shield as he rushed forward to meet the enemy, the nearest legionaries piling in on either side, and behind him. The two sides crunched together, shield to shield, close enough to hear the panted breath of the enemy and the sound of straining in their throats. Crushed inside the curve of his shield Macro worked his sword arm free and stabbed it at any expanse of barbarian cloth, or flesh that came within range. The spears and long swords of the Britons were now useless in the kind of fight the shorter blades of the legions had been expressly designed for. In the press of bodies more and more of the enemy were cut down. Unable to pull back through their ranks, or even collapse, they suffered on their feet or simply bled to death, heads lolling beside the desperate expressions of their still-living comrades.
The Romans had the advantage of height on the river bank, and more solid footing, and managed to hold off the greater weight of enemy numbers. Macro had no idea how long the contest lasted. His mind was simply fixed on defying his enemy, to hold his ground. All around were the grunts and cries of men, the splashing of the red-hued river and the glitter and glare of the harsh sunlight reflecting off raised sword blades and polished helmets, now spattered with gore and mud.
