Boris Theodore Pash (1900 – 1995), born Boris Fedorovich Pashkovsky (Russian: Борис Фёдорович Пашковсий), was a colonel in the United States Army and a member of the American Brotherhood of Assassins during World War II. Pash was also the leader of Bloodstone Unit, an extremist Assassin cell active during the Vietnam War.
In 1942, he officially led the Alsos Mission, aimed at spying on secret German operations regarding their atomic bomb project as the Allies were developing their own program, the Manhattan Project. In this context, he also recruited the Londoner Eddie Gorm to infiltrate the entourage of Nazi General Gero Kramer, an SS Obergruppenführer secretly a member of the Templar Order.
World War II
Before 1940, Pash placed a mole in Jack Turpin's criminal organization, Robert Burton, a British spy who kept the colonel informed on the activities of Turpin, who was in fact the Nazi infiltrator named Otto Hammerstein.
In September 1940, Pash learned that Hammerstein tried to recruit the docker Eddie Gorm in order to steal the research of a French scientist refugeed in London. Investigating Gorm's background, Pash discovered that the former war hero was unknowingly the descendant of an Assassin bloodline. The Assassin decided to use this opportunity to finally have a spy of the Brotherhood able to reach Turpin's superior, the Templar Gero Kramer. All the Assassins that Pash had sent to infiltrate the Uranprojekt were unmasked by Kramer, prompting him to devise a plan to send an Assassin who did not knew himself that he was an Assassin.
To do so, Pash approached Gorm with another Assassin, Julia Dusk, trying to convince the man to accept Hammerstein's offer and work for the Allies as a double-agent, but the Englishman rebuffed them. However, as they were arguing, an armada of German planes attacked London and a bomb hit Gorm's house, killing his whole family. Distraught, Gorm drowned his sorrows in alcohol until Pash and Dusk found him back one week later and convinced him to accept their offer. While Gorm was convinced to work for the Americans, Pash kept from his new recruit his true allegiance to the Assassin cause.
Eventually, Gorm gained the trust of Hammerstein, and by 1942, was a member of the Schutzstaffel living in Berlin, where he was handled by Dusk. However, during a ceremony presided by Kramer and held in honor of Werner Heisenberg, the lead scientist of the Uranprojekt, Gorm blew his cover, stabbing Hammerstein in blind rage and taking Heisenberg hostage, forcing the Assassins to come to his rescue. After Gorm isolated himself and Heisenberg in a laboratory where he interrogated the scientist about the atomic project, Julia Dusk jumped through a window to save him from the soldiers who were about to capture him. They escaped, though Julia was shot, and joined Pash and Burton who were waiting for them with a car.
Despite Gorm trying to strangle Burton after recognizing him as Hammerstein's henchman, the group successfully reached their Assassin hideout in the city. While Burton tended to Dusk, Pash revealed everything to Gorm, from his allegiance to the Assassin Brotherhood to their secret war against the Templar Order. After Pash told him that he was a descendant of an Assassin bloodline, Gorm decided to join the Brotherhood. By February 1943, Pash had completed Gorm's training and decided that the time had come to act on the information that his protégé extorted from Heisenberg, sending the Assassin after Gero Kramer in Vemork, Norway.
In 1957, Pash recruited former Soviet Union hitman Alekseï Gavrani and begun training him. On February 8, both men traveled to Walter Reed Medical Center, where John von Neumann was. Gavrani dispatched the guards, giving Pash privacy with von Neumann. After killing von Neumann, Pash exited the room with an Apple of Eden in hand. He claimed that von Neumann had died from his years in Los Alamos to Gavrani before they left.
On 2 January 1963, Pash's taskforce Assassin cell known as Bloodstone Unit, captured Cooper, a Templar infiltrator. Pash himself interrogated Cooper for information. When Pash found out that Gavrani felt uneasy about his methods, Pash dismissed him for being weak-willed.
