In Sun Tzu's Art of War, spies are divided into five types: the countryside (the enemy's fellow countrymen), the inner (the officials of the enemy country), the anti-inter (bribing the enemy's spies), the dead (spreading rumors to the enemy, and after the defeat, the spies will die), and the living (the spies who can come back alive).
There were also many spies during World War II, and the most mysterious spies of the Soviet Union also helped the Soviet Union win World War II, and assisted the Soviet Union in building atomic bombs to compete with the United States.
This man was Rudolf Abel, whose real name was William August Fisher, who was born in England in 1903 to Russian-Germanic parents, and whose father, Henri henrich Fisher, was exiled for opposing the Tsarist regime and fled to England in 1901.
However, Henrich was a loyal old Bolshevik party member, and even though he was in England, he secretly transported his weapons to Russia many times, and when Rudolf was young, there would be a variety of people coming in and out of their homes, who spoke English, German, Russian, etc.
The environment in which Rudolf grew up had a great influence on Rudolph's life, and Rudolf excelled in his studies, showing outstanding talents in science, mathematics, art and music, and was proficient in the Six Chinese, when Rudolf was 18 years old, the Russian October Revolution was victorious, so Rudolf left England with his family and returned to Moscow.
In 1925 Rudolf joined the Red Army, two years later Rudolf was selected to join the Soviet National Political Protection Bureau, received more professional intelligence training, at the end of 1939 after the German invasion of Poland, the Soviet Union sent Rudolf to infiltrate the German Nazi high-level, after which Rudolph became a "German".
The Soviets fought and won many battles with the Germans, thanks to the spy Rudolf, and Rudolph also identified many German spies who infiltrated the Soviet Union, helping the Soviet Union win World War II, and after the end of World War II, the Soviet Union and the United States during the Cold War, Rudolph was sent to the United States.
Rudolph's espionage was once again perfect, helping the Soviets to produce an atomic bomb, but Rudolph ended up with a 13-year-old newspaper delivery boy named James Boza, who once paid the child and accidentally paid James a 5-cent coin containing microfilm, and James's brother-in-law was an American policeman.
Soon the American police arrested Rudolph, the United States actually admired Rudolph, no one is better than Rudolph, so he proposed to let Rudolf cooperate with the United States, but Rudolph refused, so Rudolph was imprisoned for 4 years and 8 months, the Soviet side was still unwilling to give up Rudolph, and finally ransomed Rudolph.
