the Black Front. Hirsch was sentenced to death on March 8, 1937, and on June 4 was beheaded with an axe. Perhaps the most significant Jewish resistance group within Germany for which records survive was the Berlin-based Baum Group (Baum-Gruppe), which was active from 1937 to 1942. Largely young Jewish women and men, the group disseminated anti-Nazi leaflets, and organized semi-public demonstrations. Its most notable action was the bombing of an anti-Soviet exhibit organized by Joseph Goebbels in Berlin's Lustgarten. The action resulted in mass arrests, executions, and reprisals against German Jews. Because of the reprisals it provoked, the bombing led to debate within opposition circles similar to those that took place elsewhere where the Jewish resistance was active—taking action and risking murderous reprisals vs. being non-confrontational with the hopes of maximizing survival. Netherlands In the Netherlands, the only pre-war group that immediately started resistance against the German occupation was the communist party. During the first two war years, it was by far the biggest resistance organization, much bigger than all other organizations put together. A major act of resistance was the organisation of the February strike in 1941, in protest against anti-Jewish measures. In this resistance, many Jews participated. About 1,000 Dutch Jews took part in resisting the Germans, and of those, 500 perished in doing so. In 1988, a monument to their memory was unveiled by the then mayor of Amsterdam, Ed van Thijn. Among the first Jewish resisters was the German fugitive Ernst Cahn, owner of an ice cream parlor. Together with his partner, Kohn, he had an ammonia gas cylinder installed in the parlor to stave off attacks from the militant arm of the fascist NSB, the so-called "Weerafdeling"("WA"). One day in February 1941 the German police forced their entrance into the parlor, and were gassed. Later, Cahn was caught and on March 3, 1941, he became the first civilian to be executed by a Nazi firing squad in the Netherlands. Benny Bluhm, a boxer, organized Jewish fighting parties consisting of members of his boxing school to resist attacks. One of these brawls led to the death of a WA-member, H. Koot, and subsequently the Germans ordered the first Dutch razzia (police raid) of Jews as a reprisal. That in turn led to the Februaristaking, the February Strike. Bluhm's group was the only Jewish group resisting the Germans in the Netherlands and the first active group
