The air felt cool at Cato’s back and he risked one last glance towards the wave and saw that it was no more than fifty feet behind him, an ugly churning mass of spray and brown water carrying brush and trees with it. There was a cry of terror and despair away to his right as the first of the Praetorians went down, and then the voice was instantly silenced as the man was submerged in the tumult.
Ahead, Tigellinus was no more than ten feet from the Emperor, and then he stumbled, the toe of his boot stubbing against a rock. He fell down, the dagger spilling from his fingers. Cato ran on, calling out, ‘Sire!’
Claudius looked back at Cato, wide eyed, then past him, aghast. Cato grabbed the Emperor’s arm with one hand and wrenched at the toga with the other. At once the Emperor struggled and lashed out with his spare hand. ‘Help! Murder!’
‘No, sire! The toga will weigh you down!’ Cato shouted, ripping the thick woollen material from the Emperor’s shoulder. He heard Macro cry out a short distance behind, but before he could turn to look, the wave struck. There was an instant when he felt a surge around his calves, and Cato stepped in front of the Emperor, trying to shield him with his body. The full force of the water slammed into his back, instantly wrenching him off his feet. Cato tried to stay upright, kicking down to get purchase on the ground as he was swept along. He held tightly to the Emperor, pushing Claudius up. The water surged around his head, flowing over him and roaring in his ears before he surfaced, snatching a breath.
Something struck him in the ribs, a winding blow that drove the air from his lungs in an explosive cough and water instantly flooded his mouth before he could shut it. Then he was under again, still holding the Emperor and feeling him struggling wildly in his grasp. Cato felt something solid close by and risked letting go of Claudius with one hand as he groped. He felt the branch of a tree. He clamped his fingers round the rough bark and pulled himself and the Emperor towards it. His head burst through the surface once more and Cato took a breath. Around him was a chaotic mass of spray and water and debris, with the heads of men and flailing limbs all about. Cato thought he saw Macro a short distance away, but water closed over the head before he could be sure. Claudius came up, spluttering at his side.
‘Sire!’ Cato yelled into his face. ‘Grab the branch!’
Claudius turned his head to Cato. ‘I can’t! I’m being dragged down! S-s-save yourself, young man. I’m done for!’
Cato saw that his toga was still caught round his chest and debris in the surging water was pulling at the cloth and dragging the Emperor with it. Cato grabbed at the fabric and wrenched it as hard as he could, working it free. It slipped down a little, yet Claudius was still being pulled under and let out a despairing cry before the water closed over his face again. He came up and Cato shouted, ‘Kick it free! Kick it free, or you’ll die!’
‘Yes … yes,’ Claudius spluttered. ‘Kick it free.’
While he thrashed at the material with his legs, Cato used his spare hand to try to pull the toga away from the Emperor’s body. The wool was like a live thing, squirming in the chaotic current, the folds wrapping around Cato’s hand and arm. With one last pull it came off and both men came up, heads and shoulders clear of the water as they gripped the branch. The water around them was no longer raging quite so much and Cato could see for the first time that they had been swept some distance from the end of the vale. Around them were the remains of the tables, and Cato saw Tigellinus, some fifty feet away, trying to haul himself on to one of the table tops, which was spinning round in the fast current.
‘Cato!’
He turned and saw a commotion in the water where Macro was trying to swim towards the branch. Then, between them, another figure came up coughing and hacking, his arms flailing to keep him above water. Cato saw that it was Tribune Burrus.
‘Over here, sir! Here!’ Cato waved his arm and Burrus began to kick out towards him. The tribune reached the branch and wrapped his arms over it, gasping for breath. Cato looked round and saw that Macro would join them in a moment. Then he noticed something strange a short distance ahead of them. The leading edge of the wave just seemed to have disappeared, leaving a sharp line no more than fifty feet away.
‘Oh shit,’ Cato muttered. ‘The river …’
The tree, and the men clinging to it, were being swept towards the steep riverbank and down into the river. Cato put his arm round the Emperor and clung tightly to the branch. He saw that Macro had grasped the end of a smaller branch a short distance away. Cato filled his lungs and cried out above the din of the rushing water, ‘Hold on tight! We’re going into the river!’
The end of the branch abruptly shot out into thin air for an instant. Then it tipped over the edge. Once again water closed over Cato and he felt his legs being scraped by rocks and debris as the branch dragged those hanging on to it under the raging surface of the river. The water roared in Cato’s ears and his lungs began to burn. The Emperor seemed to writhe against him, but it was impossible to tell if he was struggling or simply being battered about by the current. Then there was a swirl in the water and the branch broke the surface. Cato snatched a deep breath.
‘Sire, are you all right? Sire!’
The Emperor retched and spluttered and rested his head on the branch as his body was wracked by a coughing fit.
Cato looked round and saw that Burrus was still clinging on, but could not locate Macro. Cato turned his head from side to side, anxiously scanning the surface of the river. There were several men visible, struggling to stay afloat or striking towards the bank. Tigellinus was sprawled across the tabletop some distance away. Now that the river had absorbed most of the water unleashed by the collapse of the dam, the worst had passed, Cato realised. Except there was no sign of Macro. Then he saw a glistening hummock in the water some twenty feet away. It began to roll over and Cato realised it was a body, and then, stricken by fear, he recognised Macro’s features as his face briefly cleared the surface before submerging again.
‘Tribune!’ Cato called out. ‘Tribune Burrus, sir!’
Burrus looked up with a dazed expression, his single eye blinking.
‘Look after the Emperor, sir! Do you understand?’
‘Yes …’ Burrus nodded, concentrating his thoughts with some effort. Cato turned to Claudius. ‘Hold on, sire. We’ll get you out of this.’
Then he released his grip on the branch and thrust himself out towards one of the other tables that was slowly turning round in the current close to where Macro was floating. Cato pulled his chest on to the table and kicked out with his legs, striking out towards his friend who showed little sign of life. As he came within reach, Cato threw out his arm, his fingers struggling for purchase in the folds of Macro’s tunic. He tightened his grip and pulled Macro on to the table. A thin trail of blood etched its way down Macro’s forehead and Cato saw a cut on his forehead.
‘Macro!’ He shook his shoulder violently. ‘Macro! Open your eyes.’
His friend’s head rolled limply back on to the planks of the table and his jaw sagged open. Cato slapped him hard. ‘Open your bloody eyes!’
There was no response and Cato slapped him again, harder. This time Macro’s head jerked up and his eyes blinked open. His jaw clenched defiantly. ‘Which one of you bastards hit me, eh?’
Then the water in his lungs caused him to cough and retch agonisingly and it took him a while to recover sufficiently to register Cato’s presence. He smiled weakly. ‘What the hell happened to you, lad? You look a right state.’
Cato could not help smiling back in delight. ‘Me? You should see yourself.’
‘What … what happened?’ Macro grimaced. ‘Feels like some bastard’s dropped a rock on my head.’
‘You must have hit your head on the branch when we went into the river.’
