Hartmann stood as erect as he could, turning his head to look at Lindsay. His wrists were bound behind his back. Again his eyes seemed to attempt to convey some message to the Englishman.
'Is that really necessary?' snapped Lindsay.
'Keep your voice down,' she hissed. 'It was done on the direct orders of Heljec. A German armoured column is approaching the gorge below. That is why the Amazon Brigade marched through it so openly earlier. It is a trap and the Germans are falling into it. Look down – not too close!' she warned.
The mutter of many slow-moving engines drifted up from the depths of the gorge. Peering over the edge, Lindsay saw the head-of the toy-like column snaking its way along the twisting defile. There was just enough light to see that this was an expedition in force.
Armoured cars and motorcyclists preceded the convoy. Behind came the tanks, nose to tail, their gun barrels swivelled to one side or the other at maximum elevation. Even to Lindsay's non-military eye this powerful cavalcade seemed useless, they would never be able to elevate the barrels to anything like the angle required to bombard the heights on which Heljec had placed his men.
And now he understood all the effort which had gone into shifting the boulders to the brink, the reason for the thick poles like pine trunks the Partisans had dug beneath the rocks and which they manned like giant levers, two or three Partisans to a pole.
Doubtless the German commander had taken a gamble – because it was established military lore that in this part of the world the Wehrmacht never moved at night. He was hoping to slip through under the cover of dusk – to break out into the open plain beyond which Lindsay had seen earlier to the south.
It was military madness. It would be a massacre.
Hartmann, compelled by Heljec to watch the destruction of his countrymen, stood close to Lindsay now with Paco between them. The Abwehr officer leaned forward to take a closer look into the abyss. He took a furtive step forward -and Paco ground her booted heel hard on the German's foot.
'You want to die early, you maniac?' she whispered.
'What happened?' murmured Lindsay.
'Your German is a brave man. He was trying to kick a stone over the edge. He could have caused a gravel slide – warning the column down there. It is, of course, doomed…'
There was no hint of excitement, of triumph in her voice – only an infinite weariness at the thought of the imminent catastrophe and bloodshed.
Soundless as a cat, Heljec ran along the line of men holding the levers. Gentle as a cat, he touched each team leader's elbow as he passed. He was signalling them to launch the attack.
Only one truckload of infantry, the two trucks containing the mortar teams, and the half-track bringing up the rear remained outside the gorge. Within a minute they would have joined their companions. inside the defile.
Jaeger had taken back his field-glasses from Schmidt and stared up like a man obsessed, the eyepieces screwed hard against his flesh. The caterpillar tracks ground forward under them. For a split second Jaeger thought fatigue was affecting his vision.
A giant boulder was wobbling. Rocking back and forth. Then the whole rampart began to tremble as though shaking under growing vibrations of an earthquake. A gap appeared on the skyline, still faintly visible. The giant had plunged down…
It struck an outcrop, ricocheted with all its massive weight across the gorge to hammer the opposite slope, bounced back in mid-air and then fell vertically. It landed smack on the top of the open turret of a tank. The commander was pounded to a jelly as the boulder collapsed the turret and concertinaed the chassis.
The squashed metal pile halted all the column behind it. More boulders hammered down, falling with tremendous velocity and landing on trucks full of men.
The screaming started. Agonizing, wailing screaming which went on and on and on. The night was filled with the cries of men mutilated, terrified, confused. The banshee-like wailing was the worst.
'Halt! Stop the bloody truck!'
Jaeger reacted instantly. Leaping from the half- track he ran to the lead truck carrying mortar teams, jumped on the running-board and yelled at the startled driver who jammed on his brakes and nearly threw Jaeger to the ground.
One other man had kept his head. Curiously it was the courier on the motorcycle who earlier had brought to Jaeger 'evidence' from Schrenk of the earlier passage of the Amazon Brigade. In his anxiety to reach Jaeger he threw overboard a stringent order subject to immediate court-martial. He drove with his headlight full on. Standing up in the stationary half-track, his machine-pistol cocked, Schmidt watched the approaching headlamp weaving with great skill in and out among the rocks scattered over the lower slopes. What the hell message was he bringing?
'Colonel Jaeger…' The courier had skidded his machine to a halt and was gasping to regain his breath. 'You are now the senior officer… Colonel Schrenk is dead…'
'Get your breath back, man…'
'I'm all right, sir…'
'Take this instruction as a direct order to be obeyed without question by every officer in the column. Abandon all vehicles. The tanks – everything. Only portable weapons to be taken. You understand?'
'Perfectly, sir…'
'The surviving troops are to take up positions on the eastern slope – the eastern. Understood?'
'Yes, sir…'
'I will have any man who does not obey my next order shot. Under no circumstances are they to open fire on the enemy. Please repeat my instructions..
In the distance they could hear the boulders falling, a clang of rock against metal. Desultory fire. Jaeger stood calmly and patiently as the courier repeated the orders almost word for word.
'Get going,' said Jaeger. 'And good luck…'
'I don't understand… began Schmidt who had jumped down beside the Colonel as the motorcyclist drove off, headlamp blazing.
'Neither will the enemy,' Jaeger replied grimly. 'Now, let's organize our own nasty little surprise for those swine on the heights.'
He ordered the mortar teams out of their trucks with all their equipment. They were to spread out. They were to take up position on the eastern slope opposite the heights where the Partisans were emplaced. Still limping slightly, he followed the mortar teams, moving with astonishing agility over the rough terrain.
'No firing until I give the order… aim for just behind the wall of boulders up there… take your time…'
This is the Jaeger I've always know, Schmidt thought as he followed his chief. Decisive, controlled, won't be rushed even when all hell is breaking loose.
All hell had broken loose. Because of Schrenk's stupidity the element of surprise was complete. The boulders continued tumbling down, rock clanged on metal as they hit the vehicles. And now grenades were tossed from the heights like exploding rain. There was the killing crackle of shrapnel.
But under Jaeger's command what had almost become a disorganized column fleeing in terrified chaos was taking, up the designated positions. Jaeger waited until every mortar was emplaced to his satisfaction, then gave the order.
'Fire a ranging shot.'
On the hilltop Paco had borrowed a pair of night- glasses from Milic. She had focused them on the vague outline of the German column. Men sweated as they heaved at the poles to lever more boulders over the edge. Hartmann, still with wrists bound, stood next to her. His guards had abandoned him as they lobbed grenades into the black gulf.
On the other side she was flanked by Lindsay who glanced round and saw Reader close behind, his face oddly expressionless. As Paco continued staring through her glasses the darkness was illuminated by blue moonlight. A flare fired by the Germans hovered. Paco stared hard through the twin lenses.
