The Second Sabotage in the Giv'at-Olga Police Station

The sabotage mission was assigned to Simcha Denzig (''Siyomke'), a member of kibbutz Sarid, who served as a paramedic in the Company B of the Second Battalion. During his Palmach service, 'Siyomke' acquired painting skills while working in Giv'at-Brenner. By order of the 2nd Battalion commander, Pinchas Veinshtein, 'Siyomke' joined a contractual group of Jewish painters that worked in painting the police building in Giv'at Olga. After a few working days, during which 'Siyomke' planned the operation, the sabotage was executed. On January 20th 1946, a vehicle entered the station's premises carrying 8 cans full of explosives disguised as painting materials. On that day, a fellow member in 'Siyomke's company from kibbutz En-Hamifratz named Mark Atsmon arrived at the station disguised as a plumber coming to check the water regularity on the premises. He carried delay igniters on him for the sabotage. 'Siyomke' and Mark's professional knowledge in explosives was based on the training they had previously received from Chaim Zinger, the main sabotage instructor of the Palmach. After planting the igniters and activating the delay detonator, the two escaped the Giv'at-Olga police station to Hadera.
The British apparently received a telephone instruction to evacuate the building and stay clear of it. The instruction was not fulfilled. Seventeen British soldiers and Arab workers who worked in restoring the station were hurt by the explosion. One of them, a British soldier, died of his wounds.
