The final desperate moments closed in on him. His night probe had ended.
Slowly but relentlessly the net tightened as Macklin's dwindling force fought on. The bodies of the dead and wounded lay amid a sea of spent cartridge casings.
The sun had burned away the mist. They could see their targets better now, but so could the men surrounding them. There was no fear. They knew their chances of escape were impossible from the start.
Fighting far from the shores of their island fortress was nothing new to British fighting men.
Macklin hobbled over to Shaw. The lieutenant had his left arm in a bloodstained sling and a foot wrapped in an equally bloody bandage. "I'm afraid we've run our course, old man. We can't keep them back much longer."
"You and your men have done a glorious job," said Shaw. "Far more than anyone expected."
"They're good boys, they did their best," Macklin said wearily. "Any chance of breaking through that bloody hole?"
"If I ask Caldweiler one more time how he's doing, he'll probably bash my brains out with a shovel."
"Might as well toss a charge down there and forget it."
Shaw stared at him thoughtfully for a moment. Then suddenly he scrambled over to the edge of the pit.
The men hauling up the buckets looked as if they were ready to drop from exhaustion. They were drenched in sweat and their breath came in great heaves.
"Where's Caldweiler?" asked Shaw.
"He went down himself. Said no one could dig faster than him."
Shaw leaned over the edge. The air shaft had curved and the Welshman was out of sight. Shaw yelled his name. A lump of dirt shaped like a man came into view far below. "What now, damn it?"
"Our time has run out," Shaw's voice reverberated down the shaft. "Any chance of blowing through with explosives?"
"No good," Caldweiler shouted up. "The walls will cave in."
"We've got to risk it."
Caldweiler sank to his knees in total exhaustion. "All right," he said hoarsely. "Throw down a charge. I'll give it a try."
A minute later, Sergeant Bentley lowered a satchel containing plastic explosives. Caldweiler gently tapped the pliable charges into deep probe holes, set the fuses and signaled to be pulled to the surface.
When he came into reach, Shaw took him under the arms and dragged him free of the pit entrance.
Caldweiler was appalled by the scene of carnage around him. Out of Macklin's original force, only four men were unwounded, yet they still kept up a vicious fire into the woods.
The ground suddenly rumbled beneath them and a cloud of dust spewed from the air shaft. Caldweiler immediately went back in. Shaw could hear him coughing, but his eyes could not penetrate the swirling haze.
"Did the walls hold?" Shaw yelled.
There was no answer. Then he felt a
tug on the rope and he began pulling like a madman. His arms felt as if they were about to drop off when Caldweiler's dust-encrusted head popped up.
He sputtered incoherently for a moment and finally cleared his throat. "We're in," he gasped. "We've broken through. Hurry, man, before you get yourself shot."
Macklin was there now. He shook Shaw's hand. "If we don't see each other again, all the best."
"Same to you."
Sergeant Bentley handed him a flashlight. "You'll need this, sir."
Caldweiler had knotted three ropes together, increasing the length. "This should see you to the floor of the quarry," he said. "Now, in you go."
