His elder brother, Pinchas, was arrested and afterwards escaped from Latrun Detention Camp with 19 other members, tunnelling for many months, through one of the barracks to reach their freedom, and continue their fight . Chaim was educated in the spirit of love for the people and the homeland, identifying strongly with the underground’s battle against British rule and occupation.
