was part of the Operation Tempest, a nationwide insurrection plan. During the Warsaw Uprising, the Polish Home Army's Battalion Zośka was able to rescue 380 Jewish prisoners (mostly foreign) held in the concentration camp "Gęsiówka" set up by the Germans in an area adjacent to the ruins of former ghetto. These prisoners had been brought from Auschwitz and forced to clear the remains of the ghetto. A few small groups of ghetto residents also managed to survive in the undetected "bunkers" and to eventually reach the "Aryan side". In all, several hundred survivors from the first uprising took part in the later uprising (mostly in non-combat roles such as logistics and maintenance, due to their physical state and general shortage of arms), joining the ranks of the Polish Home Army and the Armia Ludowa. According to Samuel Krakowski from the Jewish Historical Institute, "The Warsaw Ghetto Uprising had a real influence ... in encouraging the activity of the Polish underground." A number of survivors of the Warsaw Ghetto Uprising, known as the "Ghetto Fighters", went on to found the kibbutz Lohamei HaGeta'ot (literally: "Ghetto Fighters'"), which is located north of Acre, Israel. The founding members of the kibbutz include Yitzhak Zuckerman (Icchak Cukierman), who represented the ŻOB on the 'Aryan' side, and his wife Zivia Lubetkin, who commanded a fighting unit. In 1984, members of the kibbutz published Daphei Edut ("Testimonies of Survival"), four volumes of personal testimonies from 96 kibbutz members. The settlement features a museum and archives dedicated to remembering the Holocaust. Yad Mordechai, a kibbutz just north of the Gaza Strip, was named after Mordechaj Anielewicz. In 2008, Israel Defense Forces Chief of Staff Gabi Ashkenazi led a group of Israeli officials to the site of the uprising and spoke about the event's "importance for IDF combat soldiers". In 1968, the 25th anniversary of the Warsaw Ghetto Uprising, Zuckerman was asked what military lessons could be learned from the uprising. He replied: On 7 December 1970, West German Chancellor Willy Brandt spontaneously knelt while visiting the Monument to the Ghetto Heroes memorial in the People's Republic of Poland. At the time, the action surprised many and was the focus of controversy, but it has since been credited with helping improve relations between the NATO and Warsaw Pact countries. Many people from the United States and Israel came for the 1983 commemoration. The last surviving Jewish resistance fighter,
