Mallory now abandoned the ladder at the top of one of its zigs and struck vertically up the cliff-face. The rockface, providentially, was not completely smooth, but such hand – and footholds as it afforded were few and small and awkwardly situated, making for a climb that was as arduous as it was technically difficult: normally, had he been using the hammer and pitons that were stuck in his belt, Mallory would have regarded it as a climb of no more than moderate difficulty: but the use of pitons was quite out of the question. Mallory was directly opposite the top of the dam wall and no more than 35 feet from the nearest guard: one tiny chink of hammer on metal could not fail to register on the hearing of the most inattentive listener: and, as Mallory had just observed, inattentive listening was the last accusation that could have been levelled against the sentries on the dam. So Mallory had to content himself with the use of his natural talents and the vast experience gathered over many years of rock-climbing and continue the climb as he was doing, sweating profusely inside the hermetic rubber suit, while Miller, now some forty feet below, peered upwards with such tense anxiety on his face that he was momentarily oblivious of his own precarious perch on top of one of the slanted ladders, a predicament which would normally have sent him into a case of mild hysterics.
Andrea, too, was at that moment peering at something about fifty feet away, but it would have required a hyperactive imagination to detect any signs of anxiety in that dark and rugged face. Andrea, as the guards on the dam had so recently been doing, was listening rather than looking. From his point of view all he could see was a dark and shapeless jumble of wetly glistening boulders with the Neretva rushing whitely alongside. There was no sign of life down there, but that only meant that Droshny, Neufeld and his men, having learnt their lessons the hard way – for Andrea could not know at this time that Neufeld had been wounded – were inching their way forward on elbows and knees, not once moving out from one safe cover until they had located another.
A minute passed, then Andrea heard the inevitable: a barely discernible ‘click’, as two pieces of stone knocked together. It came, Andrea estimated, from about thirty feet away. He nodded as if in satisfaction, armed the grenade, waited two seconds, then gently lobbed it downstream, dropping flat behind his protective boulder as he did so. There was the typically flat crack of a grenade explosion, accompanied by a briefly white flash of light in which two soldiers could be seen being flung bodily sideways.
The sound of the explosion came clearly to Mallory’s ear. He remained still, allowing only his head to turn slowly till he was looking down on top of the dam wall, now almost twenty feet beneath him. The same two guards who had been previously listening so intently stopped their patrol a second time, gazed down the gorge again, looked at each other uneasily, shrugged uncertainly, then resumed their patrol. Mallory resumed his climb.
He was making better time now. The former negligible finger and toe holds had given way, occasionally, to small fissures in the rock into which he was able to insert the odd piton to give him a great deal more leverage than would have otherwise been possible. When next he stopped climbing and looked upwards he was no more than six feet below the longitudinal crack he had been looking for – and, as he had said to Miller earlier, it was no more than a crack. Mallory made to begin again, then paused, his head cocked towards the sky.
Just barely audible at first above the roaring of the waters of the Neretva and the sporadic smallarms fire from the direction of the Zenica Gap, but swelling in power with the passing of every second, could be heard a low and distant thunder, a sound unmistakable to all who had ever heard it during the war, a sound that heralded the approach of squadrons, of a fleet of heavy bombers. Mallory listened to the rapidly approaching clamour of scores of aero engines and smiled to himself.
Many men smiled to themselves that night when they heard the approach from the west of those squadrons of Lancasters. Miller, still perched on his ladder and still exercising all his available willpower not to look down, managed to smile to himself, as did Groves at the foot of the ladder and Reynolds by the bridge. On the right bank of the Neretva, Andrea smiled to himself, reckoned that the roar of those fast-approaching engines would make an excellent cover for any untoward sound and picked another grenade from his belt. Outside a soup tent high up in the biting cold of the Ivenici plateau, Colonel Vis and Captain Vlanovich smiled their delight at each other and solemnly shook hands. Behind the southern redoubts of the Zenica Cage, General Vukalovic and his three senior officers, Colonel Janzy, Colonel Lazlo and Major Stephan, for once removed the glasses through which they had been so long peering at the Neretva bridge and the menacing woods beyond and smiled their incredulous relief at one another. And, most strangely of all, already seated in his command truck just inside the woods to the south of the Neretva bridge, General Zimmermann smiled perhaps the most broadly of all.
Mallory resumed his climb, moving even more quickly now, reached the longitudinal crack, worked his way up above it, pressed a piton into a convenient crack in the rock, withdrew his hammer from his belt and prepared to wait. Even now, he was not much more than forty feet above the dam wall, and the piton that Mallory now wanted to anchor would require not one blow but a dozen of them, and powerful ones at that: the idea that, even above the approaching thunder of the Lancasters’ engines, the metallic hammering would go unremarked was preposterous. The sound of the heavy aero engines was now deepening by the moment.
Mallory glanced down directly beneath him. Miller was gazing upward, tapping his wristwatch as best a man can when he has both arms wrapped round the same rung of a ladder, and making urgent gestures. Mallory, in turn, shook his head and made a downward restraining motion with his free hand. Miller shook his head in resignation.
The Lancasters were on top of them now. The leader arrowed in diagonally across the dam, lifted slightly as it came to the high mountains on the other side and then the earth shook and ripples of dark waters shivered their erratic way across the surface of the Neretva dam before the first explosion reached their ears, as the first stick of 1,000-pound bombs crashed squarely into the Zenica Gap. From then on the sounds of the explosions of the bombs raining down on the Gap were so close together as to be almost continuous: what little time-lapse there was between some of the explosions was bridged by the constantly rumbling echoes that rumbled through the mountains and valleys of central Bosnia.
Mallory had no longer any need to worry about sound any more, he doubted he could even have heard himself speak, for most of those bombs were landing in a concentrated area less than a mile from where he clung to the side of the cliff, their explosions making an almost constant white glare that showed clearly above the mountains to the west. He hammered home his piton, belayed a rope around it, and dropped the rope to Miller, who immediately seized it and began to climb: he looked, Mallory thought, uncommonly like one of the early Christian martyrs. Miller was no mountaineer, but, no mistake, he knew how to climb a rope: in a remarkably short time he was up beside Mallory, feet firmly wedged into the longitudinal crack, both hands gripping tightly to the piton.
‘Think you can hang on that piton?’ Mallory asked. He almost had to shout to make himself heard above the still undiminished thunder of the falling bombs.
‘Just try to prise me away.’
‘I won’t,’ Mallory grinned.
He coiled up the rope which Miller had used for his ascent, hitched it over his shoulder and started to move quickly along the longitudinal crack. ‘I’ll take this across the top of the dam, belay it to another piton. Then you can join me. Right?’
Miller looked down into the depths and shuddered. ‘If you think I’m going to stay here, you must be mad.’
Mallory grinned again and moved away.
To the south of the Neretva bridge, General Zimmermann, with an aide by his side, was still listening to the sounds of the aerial assault on the Zenica Gap. He glanced at his watch.
‘Now,’ he said. ‘First-line assault troops into p
osition.’
At once heavily armed infantry, bent almost double to keep themselves below parapet level, began to move quickly across the Neretva bridge: once on the other side, they spread out east and west along the northern bank of the river, concealed from the Partisans by the ridge of high ground abutting on the river bank. Or they thought they were concealed: in point of fact a Partisan scout, equipped with night-glasses and field telephone, lay prone in a suicidally positioned slit-trench less than a hundred yards from the bridge itself, sending back a constant series of reports to Vukalovic.
Zimmermann glanced up at the sky and said to his aide: ‘Hold them. The moon’s coming through again.’ Again he looked at his watch. ‘Start the tank engines in twenty minutes.’
‘They’ve stopped coming across the bridge, then?’ Vukalovic said.
‘Yes, sir.’ It was the voice of his advance scout. ‘I think it’s because the moon is about to break through in a minute or two.’
‘I think so too,’ Vukalovic said. He added grimly: ‘And I suggest you start working your way back before it does break through or it will be the last chance you’ll ever have.’
Andrea, too, was regarding the night sky with interest. His gradual retreat had now taken him into a particularly unsatisfactory defensive position, practically bereft of all cover: a very unhealthy situation to be caught in, he reflected, when the moon came out from behind the clouds. He paused for a thoughtful moment, then armed another grenade and lobbed it in the direction of a cluster of dimly seen boulders about fifty feet away. He did not wait to see what effect it had, he was already scrambling his way up-river before the grenade exploded. The one certain effect it did have was to galvanize Droshny and his men into immediate and furious retaliation, at least half a dozen machine-pistols loosing off almost simultaneous bursts at the position Andrea had so recently and prudently vacated. One bullet plucked at the sleeve of his tunic, but that was as near as anything came. He reached another cluster of boulders without incident and took up a fresh defensive position behind them: when the moon did break through it would be Droshny and his men who would be faced with the unpalatable prospect of crossing that open stretch of ground.
Reynolds, crouched by the swing bridge with Maria now by his side, heard the flat crack of the exploding grenade and guessed that Andrea was now no more than a hundred yards downstream on the far bank. And like so many people at that precise instant, Reynolds, too, was gazing up at what could be seen of the sky through the narrow north-west gap between the precipitous walls of the gorge.
Reynolds had intended going to Andrea’s aid as soon as Groves had sent Petar and Maria back to him, but three factors had inhibited them from taking immediate action. In the first place, Groves had been unsuccessful in sending back Petar: secondly, the frequent bursts of machine-pistol firing down the gorge, coming steadily closer, were indication enough that Andrea was making a very orderly retreat and was still in fine fighting fettle: and thirdly, even if Droshny and his men did get Andrea, Reynolds knew that by taking up position behind the boulder directly above the bridge, he could deny Droshny and his men the crossing of the bridge for an indefinite period.
But the sight of the large expanse of starlit sky coming up behind the dark clouds over the moon made Reynolds forget the tactically sound and cold-blooded reasons for remaining where he was. It was not in Reynolds’s nature to regard any other man as an expendable pawn and he suspected strongly that when he was presented with a sufficiently long period of moonlight Droshny would use it to make the final rush that would overwhelm Andrea. He touched Maria on the shoulder.
‘Even the Colonel Stavroses of this world need a hand at times. Stay here. We shouldn’t be long.’ He turned and ran across the swaying swing bridge.
Damn it, Mallory thought bitterly, damn it, damn it and damn it all. Why couldn’t there have been heavy dark cloud covering the entire sky? Why couldn’t it have been raining? Or snowing? Why hadn’t they chosen a moonless night for this operation? But he was, he knew, only kicking against the pricks. No one had had any choice, for tonight was the only time there was. But still, that damnable moon.
Mallory looked to the north, where the northern wind, driving banded cloud across the moon, was leaving behind it a large expanse of starlit sky. Soon the entire dam and gorge would be bathed in moonlight for a considerable period: Mallory thought wryly that he could have wished himself to be in a happier position for that period.
By this time, he had traversed about half the length of the longitudinal crack. He glanced to his left and reckoned he had still between thirty and forty feet to go before he was well clear of the dam wall and above the waters of the dam itself. He glanced to his right and saw, not to his surprise, that Miller was still where he had left him, clinging to the piton with both hands as if it were his dearest friend on earth, which at that moment it probably was. He glanced downwards: he was directly above the dam wall now, some fifty feet above it, forty feet above the roof of the guardhouse. He looked at the sky again: a minute, no more, and the moon would be clear. What was it that he had said to Reynolds that afternoon? Yes, that was it. For now is all the time there may be. He was beginning to wish he hadn’t said that. He was a New Zealander, but only a second-generation New Zealander: all his forebears were Scots and everyone knew how the Scots indulged in those heathenish practices of second sight and peering into the future. Mallory briefly indulged in the mental equivalent of a shoulder shrug and continued on his traverse.
At the foot of the iron ladder, Groves, to whom Mallory was now no more than a half-seen, half-imagined dark shape against a black cliff-face, realized that Mallory was soon going to move out of his line of sight altogether, and when that happened he would be in no position to give Mallory any covering fire at all. He touched Petar on the shoulder and with the pressure of his hand indicated that he should sit down at the foot of the ladder. Petar looked at him sightlessly, uncomprehendingly, then suddenly appeared to gather what was expected of him, for he nodded obediently and sat down. Groves thrust his silenced Luger deep inside his tunic and began to climb.
A mile to the west, the Lancasters were still pounding the Zenica Gap. Bomb after bomb crashed down with surprising accuracy into that tiny target area, blasting down trees, throwing great eruptions of earth and stones into the air, starting all over the area scores of small fires which had already incinerated nearly all the German plywood tanks. Seven miles to the south, Zimmermann still listened with interest and still with satisfaction to the continuing bombardment to the north. He turned to the aide seated beside him in the command car.
‘You will have to admit that we must give the Royal Air Force full marks for industry, if for nothing else. I hope our troops are well clear of the area?’
‘There’s not a German soldier within two miles of the Zenica Gap, Herr General.’
‘Excellent, excellent.’ Zimmermann appeared to have forgotten about his earlier forebodings. ‘Well, fifteen minutes. The moon will soon be through, so we’ll hold our infantry. The next wave of troops can go across with the tanks.’
Reynolds, making his way down the right bank of the Neretva towards the sound of firing, now very close indeed, suddenly became very still indeed. Most men react the same way when they feel the barrel of a gun grinding into the side of their necks. Very cautiously, so as not to excite any nervous trigger-fingers, Reynolds turned both eyes and head slightly to the right and realized with a profound sense of relief that this was one instance where he need have no concern about jittery nerves.
‘You had your orders,’ Andrea said mildly. ‘What are you doing here?’
‘I – I thought you might need some help.’ Reynolds rubbed the side of his neck. ‘Mind you, I could have been wrong.’
‘Come on. It’s time we got back and crossed the bridge.’ For good measure and in very quick succession, Andrea spun another couple of grenades down-river, then made off quickly up the river bank, closely followed by Reynolds.
T
he moon broke through. For the second time that night, Mallory became absolutely still, his toes jammed into the longitudinal crack, his hands round the piton which he had thirty seconds earlier driven into the rock and to which he had secured the rope. Less than ten feet from him Miller, who with the aid of the rope had already safely made the first part of the traverse, froze into similar immobility. Both men stared down on to the top of the dam wall.
There were six guards visible, two at the farther or western end, two at the middle and the remaining two almost directly below Mallory and Miller. How many more there might have been inside the guardhouse neither Mallory nor Miller had any means of knowing. All they could know for certain was that their exposed vulnerability was complete, their position desperate.
Three-quarters of the way up the iron ladder, Groves, too, became very still. From where he was, he could see Mallory, Miller and the two guards very clearly indeed. He knew with a sudden conviction that this time there would be no escape, they could never be so lucky again. Mallory, Miller, Petar or himself – who would be the first to be spotted? On balance, he thought he himself was the most likely candidate. Slowly, he wrapped his left arm round the ladder, pushed his right hand inside his tunic, withdrew his Luger and laid the barrel along his left forearm.
The two guards on the eastern end of the dam wall were restless, apprehensive, full of nameless fears. As before, they both leaned out over the parapet and stared down the valley. They can’t help but see me, Groves thought, they’re bound to see me, good God, I’m almost directly in their line of sight. Discovery must be immediate.
It was, but not for Groves. Some strange instinct made one of the guards glance upwards and to his left and his mouth fell open at the astonishing spectacle of two men in rubber suits clinging like limpets to the sheer face of the cliff. It took him several interminable seconds before he could recover himself sufficiently to reach out blindly and grab his companion by the arm. His companion followed the other guard’s line of sight, then his jaw, too, dropped in an almost comical fashion. Then, at precisely the same moment, both men broke free from their thrall-like spell and swung their guns, one a Schmeisser, the other a pistol, upwards to line up on the two men pinned helplessly to the cliff-face.
