Vulcan's Hammer

Studying him with animosity, Fields said, "To win, you have to be on the inside."

"You have to know someone on the inside," Barris said. "And you do; you know me. I can get you in, where you will be able to attack the main trunk, not merely the branches."

"And the trunk," Fields said, "is Vulcan 3. Give us credit for knowing that, at least. That thing has always been our target." He let out his breath raggedly. "All right, Barris; I agree to your terms."

Barris felt himself relax. But he kept his expression under control. "Fine," he said.

"You're surprised, aren't you?" Fields said.

"No," he said. "Relieved. I thought possibly you might fail to see how precarious your position is."

Bringing forth a pocket watch, Fields examined it. "What do you want for the attack on the fortress? Weap­ons are still in short supply with us. We're mainly oriented around man power."

"There are weapons back at Geneva."

"How about transportation?"

"We have three high-speed military cruisers; they'll do." Barris wrote rapidly on a piece of paper. "A small concen­trated attack by skillful men-experts hitting at the vital center. A hundred well-chosen men will do. Everything de­pends on the first ten minutes in the fortress; if we succeed, it'll be right away. There will be no second chance."

Fields gazed at him intently. "Barris, do you really think we have a chance? Can we really get to Vulcan 3?" His grease-stained hands twisted. "For years I've thought of nothing else. Smashing that satanic mass of parts and tubes-"

"We'll get to him," Barris said.

Fields collected the men that Barris needed. They were loaded into the cruiser, and Barris at once headed back to­ward Geneva, Fields accompanying him.

Halfway across the Atlantic they passed an immense swarm of hammers streaking toward helpless, undefended North America. These were quite large, almost as large as the cruiser. They moved with incredible speed, disappear­ing almost at once. A few minutes later a new horde ap­peared, these like slender needles. They ignored the ship and followed the first group over the horizon.

"New types," Barris said. "He's wasting no time."

The Unity Control Building was still in friendly hands. They landed on the roof and hurried down the ramps into the building. On orders from Fields, the Healers had ceased attacking. But now hammers swarmed constantly overhead, diving down and twisting agilely to avoid the roof guns. Half of the main structure was in ruins, but the guns fired on, bringing down the hammers when they came too close.

"It's a losing battle," Daily muttered. "We're short on ammunition. There seem to be an endless number of the damn things."

Barris worked rapidly. He supplied his attack force with the best weapons available, supplies stored in the vaults below the Control Building. From the five Directors he se­lected Pegler and Chai, and a hundred of the best-trained troops.

I'm going along," Fields said. "If the attack fails I don't want to stay alive. If it succeeds I want to be part of it."

Barris carefully uncrated a manually operated fission bomb. "This is for him." He weighed the bomb in the palm of his hand; it was no larger than an onion. "My as­sumption is that they'll admit me and possibly Chai and Pegler. We can probably persuade them that we're coming over to rejoin Unity. At least we'll be able to get part of the distance in."

"Anyhow you hope so," Fields said curtly.

At sunset, Barris loaded the three cruisers with the men and equipment. The roof guns sent up a heavy barrage to cover their take-off. Hammers in action nearby at once be­gan following the ships as they rose into the sky.

"We'll have to shake them," Barris said. He gave quick orders. The three cruisers shot off in different directions, dividing up rapidly. A few hammers tagged them awhile and then gave up.

"I'm clear," Chai in the second cruiser reported.

"Clear," Pegler in the third said.

Barris glanced at the older man beside him. Behind them the ship was crowded with tense, silent soldiers, loaded down with weapons, squatting nervously in a mass as the ship raced through the darkness. "Here we go," Bar­ris said. He swung the ship in a wide arc. Into the com­munications speaker he ordered, "We'll re-form for the attack. I'll lead. You two come behind."

"Are we close?" Fields asked, a queer expression on his face.

"Very." Barris studied the ship's controls. "We should be over it in a moment. Get set."

Barris dived. Pegler's ship whipped through the dark­ness behind him, lashing toward the ground below; Chai's ship shot off to the right and headed directly over the fortress.

Hammers rose in vast swarms and moved toward Chai's ship, separating and engulfing it.

"Hang on," Barris gasped.

"The ground rose; landing brakes screamed. The ship hit, spi

"Out!" Barris ordered, pulling himself to his feet and throwing the hatch release. The hatches slid back and the men poured out, dragging their equipment into the cold night darkness.

Above them in the sky, Chai's shop fought with the hammers; it twisted and rolled, firing rapidly. More ham­mers rose from the fortress, great black clouds that swiftly gained altitude. Pegler's ship was landing. It roared over them and crashed against the side of a hill a few hundred yards from the other defense wall of the fortress.

The heavy guns of the fortress were begi

"Hurry," Barris said. "Get the bores going."

The men were assembling two gopher bores. The first had already whined into action. More tactical atomic shells from the fortress struck near them; the night was lit up with explosions.

Barris crouched down. "How are you making out?" he shouted above the racket, his lips close to his helmet speaker.

"All right," Pegler's voice said weakly in his earphones. "We're down and getting out the big stuff."

"That'll hold off the hammers," Barris said to Fields. He peered up at the sky. "I hope Chai-"

Chai's ship rolled and spun, trying to evade the ring of hammers closing around it. Its jets smoked briefly. A di­rect hit. The ship wobbled and hesitated.

"Drop your men," Barris ordered into his phones. "You're right over the fortress."

From Chai's ship showered a cloud of white dots. Men in jump suits, drifting slowly toward the ground below.

Hammers screeched around them; the men fired back with pencil beams. The hammers retreated warily.

"Chai's men will take care of the direct attack," Barris explained. "Meanwhile, the bores are moving."

"Umbrella almost ready," a technician reported.

"Good. They're begi

The fleets of screaming hammers were descending, hurtling toward the ground. Their beams stabbed into the trees and ignited columns of flaming wood and branches. One of Pegler's ca

The umbrella flickered purple. Reluctantly, it came on and settled in place. Vaguely, beyond it, Barris could make out the hammers circling in confusion. A group of them entered the umbrella and were silently puffed out.

Barris relaxed. "Good. Now we don't have to worry about them."

"Gophers are halfway along," the leader of the bore team reported.

Two immense holes yawned, echoing and vibrating as the gopher bores crept into the earth. Technicians disap­peared after them. The first squad of armed troops fol­lowed them cautiously, swallowed up by the earth.

"We're on our way," Barris said to Fields.
