July in 1944 Roul made it to Budapest. He, then opened an embassy office close to a big Jewish ghetto. He hired 400 Jews to work in his company. In the next few months he gave out protective passports to as many as 20,000 Jews. These passports gave the Jewish recipients diplomatic immunity (protects them from deportation). During this time Wallenberg also established many safe houses for the Jews, he also made sure the Swedish Flag was flown above every house, which protected them from Nazi invasion. Wallenberg also bought off German officials to keep him updated about what was being said in the Budapest police department. Despite these efforts, Wallenberg himself rescued Jews fro, deportation trains. He gave the people he could reach Swedish papers, then argued that everyone who had papers should get let off the train. During the fall of 1944, Eichmann tried to have Wallenberg killed by attacking his car. Wallenberg wasn't in his car. Even though Raoul was in great danger he persistent put efforts toward the rescues of Jews. He even directly challenged Eichmann.
