Marco led the Intelligence and Reconnaissance patrol of nine men and his sergeant, Ray Shaw, on their fourteenth reconnaissance that night. Chunjin, Marco’s orderly, appeared suddenly at his elbow, out of the almost total darkness and persistent silence. Chunjin was the captain’s interpreter; the general guide over terrain, who, no matter where they were sent in Korea always insisted gravely that he had been born within two miles of the spot. Chunjin was a very good man with a frying pan, a shoe brush, a broom, a shaving kit, and at crating and transshipping books to San Francisco. He was small and wiry. He was a very, very tough-looking fellow against any comparison. He had the look of a man who maybe had been pushed around a lot and then had taken his life into his hands by deciding not to take any more of that kind of stuff. He always looked them right in the eyes, from private to colonel, and he did not smile at any time.

“What?” Marco said.

“Bad here.”

“Why?”

“Tricky.”

“How?”

“Swamp all around thirty yards up. May be quicksand.”

“Nobody told me about any quicksand.”

“How they know?”

“All right! All right! What do you want?”

“All walk in single line next two hundred yards.”

“No.”

“Patrol sink.”

“It is tactically unsound to go forward in a single file.”

“Then patrol sink in thirty yards.”

“Only for two hundred yards ahead?”

“Yes, sir.”

“We can’t go around it?”

“No, sir.”

“All right. Pass the word.”

Raymond was at the head of the line, right behind Chunjin, in guide position. Marco finished the twelve-man line. I&R patrols go out at night, unarmed except for knives. They are unarmed because rifle fire draws other fire and I&R patrols do what they do by staying out of trouble. There was very little light from a pallid crescent of moon. There was about twenty feet of distance between each man. The line was about seventy yards long. When it had moved forward about sixty yards, two human forms rose up in front of and behind each man on the line. The forward form hit its man at the pit of the stomach with a rifle butt, while the back man brought the stock down hard at the back of each man’s head when the bodies doubled forward. Excepting Chunjin, they all seemed to go down at the same time. It was an extremely silent action, a model action of its kind. Without pause each two-man team of attackers built a litter out of the two rifles and rolled their charges aboard. Two noncoms checked each team out, talking quietly and occasionally slapping a man on the shoulder with approval and self-pleasure.

Chunjin led the litter teams on a route that was at right angles to the direction taken by the patrol, across the dark, firm terrain. Twenty-two men carried eleven bodies in the improvised stretchers at a rapid dogtrot while the noncoms sang the cadence in soft Russian. The patrol had been taken by Three Company of the 35th Regiment of the 66th Airborne Division of the Soviet Army, a crack outfit that handled most of the flashy assignments in the sector, and dined out between these jobs with available North Korean broads and the young ladies of the Northeast Administrative Area, on the stories emanating therefrom.

The patrol was taken to two trucks waiting a quarter mile away. The trucks rode them twelve miles over bad terrain to a temporary airfield. A helicopter took them north at about twelve hundred feet. They had cleared the Yalu before the first man began to climb back into sluggish consciousness to see a uniformed country boy from Ukhta holding a machine rifle at ready and grinning down at him.

Dr. Yen Lo and his staff of thirty technicians (all of whom were Chinese except two overawed Uzbek neuropsychiatrists who had jointly won an Amahlkin award; as a reward, their section had arranged for them to spend a thirty-day tour with this man whom they had always thought of as a shelf of books or the voice behind the many professors in their short lives—the living monument to, and the continental expander of, the work of Pavlov) installed their peculiar establishment during the night of July 6 and worked at the fixtures necessary until mid-morning of July 7. Their pharmacy was an elaborate affair, for one thing. For another, they had brought in four compact electronic computers. Included in the effects was an electrical switchboard that seemed large enough to have handled the lighting for the State Opera in Vienna, where, quite possibly, it originated.

Old Yen was in fine spirits. He chatted freely about Pavlov and Salter, Krasnogorski and Meignant, Petrova and Bechtervov, Forlov and Rowland, as though he had not made his departure from the main stream of their doctrine some nine years before when he had come upon his own radical technology for descent into the unconscious mind with the speed of a mine-shaft elevator. He made jokes with his staff. He taunted the two Uzbeks just as though he were not a god, about Herr Freud, whom he called “that Austrian gypsy fortune-teller” or “the Teuton fantast” or “that licensed gossip,” and he permitted his chief of staff to visit General Kostroma’s chief to arrange for the mess and the billeting of his people.

During the pleasantly cool evening before the morning when the American I&R patrol was brought in for him, Yen Lo and his staff of thirty men and women sat in a large circle on a broad, grassy space, and as the moon went higher and the hour got later, and all of the voices seemed to fall into lower pitch preparing for sleepiness, Yen Lo told them a fairy story, which was set thirty-nine centuries before they had been born, about a young fisherman and a beautiful princess who had journeyed through the province of Chengtu.

The American patrol was brought to the Research Pavilion at six-nine the following morning, July 8. Yen Lo had them bathed, then inoculated each of them personally. They were dressed again while they slept and set down, excepting for Raymond Shaw, one man to a cot to a cubicle, where Yen Lo got three implantation teams started on them, staying with each team through the originating processes until he had assured himself that all had been routined with smoothness. When he had assured himself to the point of downright fussiness, he brought his assistant and two nurses with him into the corner apartment where Raymond slept and began the complex work on the reconstruction of the sergeant’s personality.

The principles of excitation, as outlined by Pavlov in 1894, are immutable and apply to every psychological problem no matter how remote it may appear at first. Conditioned reflexes do not involve volitional thinking. Words produce associative reflexes. “Splendid,” “marvelous,” and “magnificent” give us an unconscious lift because we have been conditioned to that feeling in them. The words “hot,” “boiling,” and “steam” have a warm quality because of their associativity. Inflection and gesture have been conditioned as intensifiers of word conditionings, as Andrew Salter, the Pavlovian disciple, writes.

Salter shows that when one sees the essence of the unconscious mind to be conditioning, one is in a strategic position to develop a sound understanding of the deepest wellsprings of human behavior. Conditioning is based upon associative reflexes that use words or symbols as triggers of installed automatic reactions. Conditioning, called brainwashing by the news agencies, is the production of reactions in the human organism through the use of associative reflexes.

Yen Lo approached human behavior in terms of fundamental components instead of metaphysical labels. His meaningful goal was to implant in the subject’s mind the predominant motive, which was that of submitting to the operator’s commands; to construct behavior which would at all times strive to put the operator’s exact intentions into execution as if the subject were playing a game or acting a part; and to cause a redirection of his movements by remote control through second parties, or third or fiftieth parties, twelve thousand miles removed from the original commands if necessary. The first thing a human being is loyal to, Yen Lo observed, is his own conditioned nervous system.
