Arieh was born 1920 in the town of Lokach Poland, to Perez and Goldzand, a Zionist, cultured, Hebrew speaking family. He was a sensitive boy, with a delicate soul, and wrote poetry. Arieh joined Beitar then was recruited to Etzel in Poland. In 1938 he graduated from the first Etzel course attended by a select few only. He began working in the newspaper ‘Di Tat’ (The Deed) 1939, edited by Nathan Friedman Yelin (Yelin-Mor); they became good friends. At the outbreak of WWII, 1940, Arieh reached Israel using false papers from the British Consulate in Turkey, arranged for him by Nathan. Not to waste a Certificate, Hissya Shapira accompanied him, as his supposed wife. Upon arrival he was imprisoned in Atlit Prison Camp several weeks. There he joined Lehi. Released from Atlit, he found a way to the underground through Yerachmiel Aharonson (Elisha). Since Arieh was unknown to the authorities as an underground member, he was entrusted as Yair’s contact person. December 1941, he came to a meeting at an apartment in which members awaiting him had been arrested – thus couldn’t warn him. The British awaited him in the apartment; he got sent to Mizra prison camp. After Shamir and Giladi’s escape, the camp was moved to Latrun. Many months Arieh took part in the tunnelling process, and escaped through the tunnel November 1,1943, with 19 other inmates. From Tel-Aviv he was sent to Jerusalem to be responsible for Youth and Information He grew a beard and dressed as a Hassidic Jew for disguise. He was recalled to Tel-Aviv to become an ideology instructor. Arieh had incredible dreams about the underground’s war and the future of the state that would rise. His aspired to be tasked for combat missions, but was entrusted with intellectual-cultural assignments, due to his abilities. In Latrun he was known as Gera’s right-hand man. Perhaps this contributed to his expectations of receiving better assignments after the escape; his disappointment was immense. He slowly sank within, became depressed, and on July 15,1945, ended his life with a gunshot. He was buried at Nachalat-Yitzhak.
