The “hypnotic courier,” on the other hand, provides a unique solution. I was involved in preparing many subjects for this work during World War II. One successful case involved an Army Service Corps Captain whom we’ll call George Smith. Captain Smith had undergone months of training. He was an excellent subject but did not realize it. I had removed from him, by post hypnotic suggestion, all recollection of ever having been hypnotized.
First I had the Service Corps call the captain to Washington and tell him they needed a report on the mechanical equipment of Division X headquartered in Tokyo. Smith was ordered to leave by jet next morning, pick up the report and return at once. These orders were given him in the waking state. Consciously, that was all he knew, and it was the story he gave his wife and friends.
Then I put him under deep hypnosis, and gave him—orally—a vital message to be delivered directly on his arrival in Japan to a certain colonel—let’s say his name was Brown—of military intelligence. Outside of myself, Colonel Brown was the only person who could hypnotize Captain Smith. This is “locking.” I performed it by saying to the hypnotized Captain: “Until further orders from me, only Colonel Brown and I can hypnotize you. We will use the signal phrase ‘the moon is clear.’ Whenever you hear this phrase from Brown or myself you will pass instantly into deep hypnosis.” When Captain Smith re-awakened, he had no conscious memory of what happened in trance. All that he was aware of was that he must head for Tokyo to pick up the division report.
On arrival there, Smith reported to Brown, who hypnotized him with the signal phrase. Under hypnosis, Smith delivered my message and received one to bring back. Awakened, he was given the division report and returned home by jet. There I hypnotized him once more with the signal phrase, and he spieled off Brown’s answer that had been dutifully tucked away in his unconscious mind.
The system is virtually foolproof. As exemplified by the case, the information literally was “locked” in Smith’s unconscious for retrieval by the only two people who knew the combination. The subject had no conscious memory of what happened, so couldn’t spill the beans. No one else could hypnotize him even if they might know the signal phrase.
Not all applications of hypnotism to military intelligence are as tidy as that. Perhaps you have read The Dissociation of Personality.[Note:1] The book was based on a case reported in 1905 by Dr. Morton Prince of Massachusetts General Hospital and Harvard. He startled everyone in the field by announcing that he had cured a woman named Beauchamp of a split personality problem. Using post-hypnotic suggestion to submerge an incompatible, childlike facet of the patient, he’d been able to make two other sides of Mrs. Beauchamp compatible, and lump them together in a single cohesive personality. Clinical hypnotists throughout the world jumped on the multiple personality bandwagon as a fascinating frontier. By the 1920’s not only had they learned to apply posthypnotic suggestion to deal with this weird problem, but also had learned how to split certain complex individuals into multiple personalities like Jeckyl-Hydes.
