North Cape

Artillery opened up from somewhere deep in the foothills. The first truck was lucky and ran the ranging gauntlet. Cannon shells, four of them, burst high on either side of the first truck. As it cleared the pass, it sped for the safety of the foothills less than half a mile away. The second truck was not so lucky. It was caught by a fifth artillery shell that arrowed down into the defile and exploded. The truck disintegrated in the explosion, the gas tank and ammunition going up in a fierce welter of flame. The third truck skidded to a halt only a short distance behind and was hit almost immediately. For three more minutes a heavy barrage of fire pursued the first truck, but it managed to reach the foothills below, to which the enemy artillery men obviously could not depress their guns. Teleman's cameras faithfully recorded the action on tape. The entire sequence had taken less than two minutes, but two minutes was too long for Teleman to maintain such a low speed. Someone would be bound to notice. He increased power to bring the aircraft up to five hundred knots and forty thousand feet again as he broke out of the tight orbit and resumed his search along the border. The flight plan called for a shallow zigzag pattern along the border that would carry him fifty-odd miles into enemy territory on the first, high-altitude pass. The second pass would be modified by data from the nonvisual sensors and would concentrate on areas of heavy troop concentrations. One area particularly was read out by the flight-control complex. It indicated modifying data being received from one of the SAMOS series designated Advanced Reconnaissance 7. The satellite system had spotted an unusual degree of infrared activity twenty miles behind Chinese lines in the vicinity of Kuldja on the Ili River. The river flowed through a wide pass and crossed the border fifty miles east of the scrub town, important only as a staging point for whomever could hold it. At the moment it was in the hands of the Chinese.

Its principal danger lay in the fact that it commanded the shallow heights that led gradually to the border and the start of the Kazakh steppe, then out across the flat grasslands. The pass down which the Ili River flowed from the Tien Shan to Lake Balkhash was an arrow aimed directly at the huge Soviet military complex around the Kazakh city of Alma Alta.

The infrared patch that AR-4, satellite AR-7's predecessor, had detected immediately caused its IR and visual light lenses to shift focus. At the optimum moment, recorders were activated and they picked up two images. In its brainless way AR-4 was excited by what it saw. The visual light cameras showed a cluster of trucks and, more important, a special variable called a 210-mm cannon mounted on a massive tracked crawler. As AR4 had watched, the cannon had spat a shell. The IR cameras saw the flash of fierce gases erupting from the muzzle and immediately the computer tripped a relay that caused the tape to spurt through the reel. The visual light cameras tracked the shell in free flight as the lenses shifted focus quickly to follow the trajectory.

In twelve seconds of flight the shell flew unerringly to detonation. There was no explosion worth mentioning, merely a spreading cloud, recorded by the IR cameras until it cooled and was lost in background scatter. Program 14—designed to watch for nuclear weaponry — noted the disappointing blast and gave way to Program 1, GENERAL SURVEILLANCE.

Program a took its time digesting the data — all of three nanoseconds — then scanned rapidly across its disk memory to match this variable against any of eight billion bits of data. It found none. Program 1 reached the end of its rack and automatically tripped Program 99, code named OVERVIEW. Program 99 evaluated the data, found the flight pattern it needed, then instructed Program 1 to include the new datum in its general report. Five minutes later a coded message left AR-4 and was received by a picket ship south of Ceylon. By the time the message came to the attention of the project director on the night shift in Virginia, AR-4 was already eleven minutes away from the site deep in the Tien Shan and over East Pakistan. The task of relaying the instructions from Virginia plus the new information fell to AR-7, traveling a parallel track to AR-4, but 25o miles east and half an orbit behind.
