Keeping his shield up, Macro took the first blows without striking back as he readied his sword, holding the handle tightly and drawing it back, ready to thrust. He heard the growl of an enemy on the other side of the shield and could smell the sour odour of camels that had impregnated the man’s robes. He waited for the next blow, a cut down on to the metal trim of the shield, and then punched forwards, following up with a quick pace and another thrust which slammed into the body of the Arab. The man grunted as the breath was driven from his lungs. At once Macro swung his shield aside and stabbed with his sword. The Arab wore no armour and the point cut through the man’s robes and lost none of its impetus before it struck his ribs. As Macro made to withdraw the blade, the Arab twisted to one side, snagging the sword and almost wresting it from Macro’s hand.

‘No you don’t!’ Macro snarled, wrenching the handle. ‘Bloody rags these people dress in. Ain’t bloody fair.’

With a ripping noise the blade came free and the Arab stumbled back, winded and bleeding. He glared at Macro, raised his shield and sword and fought to recover his breath. Then he attacked again. Macro deflected the blow with his shield, cut down on the man’s wrist and then stabbed him in the throat. His foe collapsed on to his knees, dropping his sword as he clasped his neck, vainly trying to stem the blood pumping from the fatal wound. Macro stepped back a pace to quickly take stock of the situation.

To his right Cato was duelling a large Arab in a gleaming scale cuirass. A heavy curved blade, wider at the tip, slashed away at Cato’s shield, driving him back until one of the legionaries struck at the Arab’s leg, cutting through muscles and tendons. The man’s leg gave way under him, he fell back, and Cato stepped up and struck a savage blow to the man’s helmet, knocking him cold.

Along the bank of the Nile Macro could see that his men were steadily fighting their way up from the reeds. Above them, fifty paces to his left, Ajax sat on his horse, urging his men on as he punched his sword into the air. Macro turned towards a group of men who had landed from the same boat. ‘On me! Form up on me!’

The legionaries hurried into a wedge behind their centurion, and Cato, seeing them, joined the small formation.
