The Antonescu-Sima dispute erupted into violence in January 1941, when the Iron Guard instigated a series of attacks on public institutions and a pogrom, incidents collectively known as the "Legionary Rebellion." This came after the mysterious assassination of Major Döring, a German agent in Bucharest, which was used by the Iron Guard as a pretext to accuse the "Conducător" of having a secret anti-German agenda, and made Antonescu oust the Legionary Interior Minister, Constantin Petrovicescu, while closing down all of the Legionary-controlled "Romanianization" offices. Various other clashes prompted him to demand the resignation of all Police commanders who sympathized with the movement. After two days of widespread violence, during which Guardists killed some 120 Bucharest Jews, Antonescu sent in the Army, under the command of General Constantin Sănătescu. German officials acting on Hitler's orders, including the new Ambassador Manfred Freiherr von Killinger, helped Antonescu eliminate the Iron Guardists, but several of their lower-level colleagues actively aided Sima's subordinates. Goebbels was especially upset by the decision to support Antonescu, believing it to have been advantageous to "the Freemasons."
