Scholar, writer and active Zionist revolutionary Israel Eldad was born in Galicia in 1910. Invited by Menachem Begin, he joined the Warsaw leadership of B’rit Trumpeldor – “Betar” – the youth section of Jabotinsky’s Revisionist Zionist Party. Arriving in Palestine in 1941, he joined the underground as a member of Lehi Headquarters Staff. During the crucial years of World War II, when the British Mandatory Government was attempting to appease the Arabs by conducting a policy of repression against Palestine’s Jewish community, Eldad made secret broadcasts, wrote articles for underground publications and edited the Wall Newspaper – “illegal” bulletins pasted on the walls at night – since compiled in book form as Let the Walls Speak. While attempting to escape arrest by the British police, Eldad suffered a serious back injury. Dramatically freed from his military guards by Lehi comrades in 1946, he resumed his work in the underground movement until the establishment of the State of Israel . He wrote Ma’aser Rishon (The First Tithe), which deals with the Hebrew underground movement and his part in it.
