As he dropped down from his saddle, Cato gestured for one of the command post orderlies to bring him a shield and he swiftly raised it up as the first of the enemy slingshot began to whip down, smacking into the sandy ground. All around, the arrows and slingshot clattered off the shields of the legionaries. A handful of arrows pierced the leather covers and lodged in the layers of laminated wood, while other missiles succeeded in striking home. Close by, Cato saw an optio's head snap back as he caught a deflection off the top of his shield. The slingshot shattered his skull and the man fell to the ground and lay still. More men were struck, the majority wounded, but some killed outright, amid the ranks of the legion. Macro's cohort, being the largest and nearest to the enemy, took the brunt of the damage. Keeping a watchful eye out for any missiles, Cato was gratified by the sight of the men closing ranks wherever one of their comrades was struck down.
The exchange of missiles from both sides continued unabated for what seemed far longer than it actually was. Cato wondered how much his men could take before their ranks were thinned out enough for the enemy to break through on their first charge. Already, over a hundred of his men were down, he estimated, with more being hit all the while. And then the enemy's barrage slackened and died away as they began to expend their ammunition. Several horns blasted out and the Nubians let out a bloodthirsty roar at the signal, and then surged forward in a charge over the final strip of sand separating them from the Romans.
'Javelins!' Macro called out and the front rank rose up from behind their shields and drew their throwing arms back. The fleetest of the Nubians was already within range of the lightest javelins. Macro snatched a breath and cried out, 'Release!'
The legionaries hurled their right arms forward and the javelins leaped from their hands. Although the javelins had the least range of the missiles the Romans used to whittle down their attackers, they were almost as lethal as the bolt throwers, and Macro watched with cool satisfaction as the first volley skewered many of the Nubians leading the charge. At once the men in the second line of legionaries handed a fresh javelin to their comrades and a follow-up volley landed amongst the enemy, the heavy shafts bursting through shields and flesh and bone with flat thuds. There was just time for a third release of javelins before the front ranks wrenched out their short swords, swiftly ordered their ranks and presented their shields to the enemy.
Macro took his place in the middle of the cohort, in the second rank, ready to enter the fight at the first opportunity. The Nubians, having suffered severe casualties in the final charge, were robbed of impetus as they struck the Roman line, arriving as individuals and small clusters of lightly armoured warriors. Years of hard training had prepared the legionaries for close combat and the Nubians were cut down from sword thrusts from the side as they attempted to duel the man directly in front of them. The advantage did not last long, as more and more of the enemy joined the fight. As the enemy warriors surged forward against the bowed line of shields, Macro could not see an end to them before those at the back merged into the dust kicked up by thousands of feet.
'Hold on, lads!' he called out at the top of his voice. 'Hold the line!'
The legionaries alternated between quick thrusts with their nimble short swords and punching their heavy rectangular shields forward. The heavy chain mail and scale armour and sturdy helmets gave them far greater protection than most of the men opposed to them. Prince Talmis had few regular soldiers, and aside from some eastern mercenaries and the Arabs, his army was mostly made up from tribesmen. They carried an assortment of spears, swords and clubs, and carried flimsy hide shields. Consequently, they died in droves as they came up against the men of the First Cohort and the auxiliaries on either side.
The soldier in front of Macro made a thrust and then howled in agony as he withdrew his arm. A sword blow had nearly severed his wrist and the useless fingers twitched and released the blade. Macro pushed past him as the legionary groaned and clutched his mutilated limb to his chest, blood spurting down the silvered scales of his armour. Macro crouched slightly, carrying his weight on the balls of his feet, ready to move swiftly. He held his shield up to protect his face and stared over the rim at his enemies as he held his sword poised.
A large warrior in a thick leather cuirass held a heavy curved sword in both hands above his head. His eyes met Macro's and he smiled savagely as he stretched his arms back to make a powerful blow. Then he slashed down. Macro saw that the blade would split his shield in two, and take his left arm with it. He sprang forward, inside the arc of the massive blade and slammed his shield into the man's chest and head. The Nubian's arms struck the rim of the shield and the sword leaped from his hands, embedding the point in the sand behind Macro. He punched his blade into the Nubian's side, ripped it out and thrust again before stepping back into the line of the First Cohort. The Nubian stumbled away and was lost amid swirling robes of two Arabs with spears who took his place in front of the centurion. They immediately jabbed at Macro but their weapons were easily blocked by the shield and Macro made no attempt to step forward and strike at them. Their futile blows thudded against the leather surface until the press of their comrades behind them forced them right up against the line of legionaries.
This was the kind of fighting which the legionaries' equipment had been designed for and at which the soldiers excelled, and all along the line the Nubians found themselves confronted by an unbroken wall of heavy shields behind which well-armoured men stood their ground, striking brutally into the ill-protected bodies packed together beyond the shields. Mortally wounded and injured Nubians fell before the Roman line, and the terrified cries of the still living were stifled as their comrades trampled over them to get at the legionaries. Most were driven on by courage, hatred of Rome and the prospect of looting the province. Others, even the cowards, had no choice as there was no way to escape the battle through the dense mass of bodies surging forward. Those far enough back to be subjected to the continued fall of Roman arrows could do nothing to avoid the deadly barbs, only pray to their gods for protection.
The Nubians were spared the danger of the bolt throwers as Cato had given the order for them to conserve ammunition rather than fire blind into the dust that obscured the view a short distance from the battle line. The crews were whipping their mule trains as the carts on which the bolt throwers were mounted were driven back to the second position Cato had chosen the previous evening.
Slowly the vast numbers of the enemy began to tell and the First Cohort was forced to give ground, step by step. Men were falling, caught by spear thrusts through gaps in the shield wall, or sometimes overwhelmed when one of the Nubians managed to wrench a shield aside long enough for one of his fellows to strike a blow at the legionary behind. Though the losses of the Nubians were far greater, Cato could see that the four-deep line with which the cohort had begun the battle was reduced to three men in most places. The bowed-out formation was steadily flattened, and then began to curve inwards as the more solid formations on either side of the First Cohort still managed to hold their ground. Out on the wings the cavalry cohorts were fighting off a second, half-hearted attack by the enemy horsemen. The battle was going to plan, Cato realised, and he promised a generous offering to Fortuna if luck continued to favour the side of Rome, as the battle entered the decisive phase. It all depended on Macro and the First Cohort, holding their formation as they gradually fell back.
'Sir?'
Cato turned to see an optio standing beside his horse. 'Yes?'
