Gold's depiction reveals a vast network of research divisions operating across the regions under Chinese control. He emphasizes that Unit 731 was a systematic and intentional endeavor, endorsed by the highest ranks of Japan's military and medical establishments.

Context

• The unit was led by General Shiro Ishii, a microbiologist and army medical officer, who was instrumental in its establishment and operations.
• The activities of Unit 731 have had lasting effects on international relations, particularly between Japan and China, as well as other countries affected by their experiments.
• Anda was one of several sites used by Unit 731, a covert biological and chemical warfare research and development unit of the Imperial Japanese Army during the Second Sino-Japanese War (1937-1945) and World War II. The unit was notorious for its inhumane experiments on humans.
• The development of biological weapons targeting animals likely involved pathogens that could cause diseases like anthrax or glanders, which are known to affect livestock and can be transmitted to humans.
• The use of diseases like typhus as a weapon was part of a larger effort to incapacitate populations and armies. Typhus, spread by lice, can cause severe illness and was used to create chaos and weaken resistance in occupied areas.
• Both diseases are highly infectious and have been used historically as biological weapons. The bubonic plague, caused by the bacterium Yersinia pestis, is infamous for causing the Black Death in the 14th century. Cholera, caused by the bacterium Vibrio cholerae, leads to severe dehydration and can be fatal if untreated.
• The activities of Unit 1855 and similar units contributed to the development of international laws and conventions aimed at prohibiting biological and chemical warfare, such as the Geneva Protocol and later the Biological Weapons Convention.
• During World War II, Japan occupied Singapore from 1942 to 1945. This period was marked by harsh military rule and significant suffering for the local population. The presence of Unit 731 in Singapore would have been part of Japan's broader strategy to expand its biological warfare capabilities in Southeast Asia.
• Prominent Japanese medical professionals and researchers were recruited to lend scientific credibility to the experiments. This collaboration was seen as a way to advance Japan's medical and scientific knowledge, albeit through unethical means.

Attempts were undertaken to sanitize and conceal the significance of this notorious military group.

As the tide of war turned against Japan, the leaders responsible for Unit 731 consciously sought to destroy all traces of their horrific deeds and conceal the full scope of their vile actions.

Facing certain defeat, Japan methodically took apart its facilities and destroyed any potential incriminating evidence.

Gold describes the intentional destruction of Unit 731's facilities, including those at Pingfang and Zhongma, as the Soviet troops progressed into Manchuria. He emphasizes the work of a compact group dedicated to dismantling the premises and eradicating all traces of their experimental endeavors. Members of Unit 731 quickly departed from Manchuria, taking advantage of rail and sea transport to avoid falling into Soviet hands.

Context

• In August 1945, the Soviet Union declared war on Japan and invaded Manchuria, prompting the Japanese to destroy evidence of their activities to prevent capture and prosecution.
• Unit 731 was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army during World War II, notorious for conducting lethal human experimentation.
• The use of rail and sea transport was a strategic choice to quickly evacuate personnel and avoid the advancing Soviet forces, who were known for their swift and decisive military operations.

Commanders of Unit 731 entered into clandestine discussions and pacts with the American forces in occupation to hide crucial details.

This section unveils a somber chapter related to Unit 731 in the aftermath of the conflict. Gold describes how leaders such as Naito Ryoichi cleverly avoided punishment and capitalized on their immorally gained knowledge by exploiting the United States' changing priorities as the Cold War began. In September 1945, at the Yokohama pier, Hal Gold recounts the initial encounter between American microbiologist Lieutenant Colonel Murray Sanders and Naito. Sanders was misled by Naito, his "interpreter," who kept the actual operations and objectives of Unit 731 hidden from him. Gold depicts Naito as skillfully controlling the release of information, leading Sanders to initially underestimate the scope of Japan's biological warfare activities. Gold later reveals a critical juncture where Sanders, feeling disheartened by the lack of progress in the investigation, subtly suggested to Naito that the Soviets might intervene. Sanders capitalized on the intense fear of communist retaliation to obtain crucial information confirming the participation of Japan's armed forces in biological warfare efforts. General MacArthur decided to grant the leaders of Unit 731 exemption from prosecution in exchange for access to their experimental data. The narrative by Gold describes how Lieutenant Colonel Arvo Thompson, a skeptical investigator, carried out a later investigation and, despite approaching a better understanding of the truth, failed to completely grasp the involvement of civilians in the unit's activities.

Gold unveils the intricate web of dialogues between the leaders of Unit 731, including Ishii, and representatives from the United States, utilizing declassified documents and private records of the talks as sources. The team under Ishii's command was granted immunity from prosecution provided that they exclusively shared their research outcomes with the United States. A confidant of Ishii played a crucial role by advocating in the Japanese legislature for immunity from war crimes prosecution. Gold explores the contrasting objectives of the U.S. and the Soviet Union, highlighting the U.S.'s intention to obscure information and capitalize on the findings from Unit 731 during the early stages of the Cold War. In contrast, the Soviets, armed with information from the confessions of captured Japanese personnel, intended to disclose and employ these disclosures for propaganda purposes. Gold emphasizes that it was General Umezu Yoshijiro, the Chief of the General Staff, who single-handedly decided against a biological attack on the United States in 1945, positing that such an action would have prolonged the conflict, transforming it into an endless battle between mankind and disease. Gold highlighted that this decision ensured the individuals in Unit 731 remained unaccountable, cloaked in obscurity. Gold concludes this section by revealing the disturbing reality that individuals who once served in Unit 731 ascended to prominent positions in Japan, notably in academia, pharmaceutical industries, and the upper tiers of governmental power after the conflict ended.

The deep-seated influence and importance that originated from the operations conducted by Unit 731.

The consequences stemming from the activities of Unit 731 extend beyond the immediate agony experienced by both the victims and those who committed the acts. Gold delves into the potential consequences that arose from the experimental activities of the unit and the continuous investigations into its effects.

The potential that the United States and other countries might employ the outcomes and studies carried out by Unit 731 throughout the period of the Cold War.

Gold argues that the U.S. government significantly impacted the trajectory of the Cold War by granting the leaders of Unit 731 exemption from prosecution in exchange for their experimental findings. He suggests that this team's discoveries might have been utilized by the United States to improve its capabilities in biological warfare. Gold discusses the indirect evidence that supports the accusation of American engagement in biological warfare during the Korean War, which includes a bomb exhibited at the Unit 731 Museum in Manchuria that is purported to have been found in Korea. Gold reveals the appearance of a mysterious disease that caused extensive bleeding and high temperatures in American troops during the Korean War, an illness unfamiliar to Western medical science but extensively studied within the scope of Unit 731's experiments, further complicating the intricate enigma. He emphasizes that throughout the outbreak, researchers from the U.S. Army sought knowledge from those who had formerly been part of Unit 731, suggesting a potential trade of specialized skills. The writer examines the 1948 incident at the Teikoku Bank, proposing that it might be an additional outcome arising from the operations of Unit 731. In this bizarre case, a man poisoned bank employees under the guise of providing prophylactic treatment, a strategy that disturbingly echoes the experimental practices conducted by the notorious Unit 731. Gold reveals insights from autopsies that question the authenticity of the case and suggest that the chemical used, a mixture created by Japan's military for experiments on prisoners, was acetone cyanohydrin.
