This article: Almost immediately after the legal Solidarity leadership had been arrested, underground structures began to arise. On April 12, 1982, Radio Solidarity began broadcasting. On April 22, Zbigniew Bujak, Bogdan Lis, Władysław Frasyniuk and Władysław Hardek created an Interim Coordinating Commission (Tymczasowa Komisja Koordynacyjna) to serve as an underground leadership for Solidarity. On May 6 another underground Solidarity organization, an NSSZ "S" Regional Coordinating Commission (Regionalna Komisja Koordynacyjna NSZZ "S"), was created by Bogdan Borusewicz, Aleksander Hall, Stanisław Jarosz, Bogdan Lis and Marian Świtek. June 1982 saw the creation of a Fighting Solidarity (Solidarność Walcząca) organization.Throughout the mid-1980s, Solidarity persevered as an exclusively underground organization. Its activists were dogged by the Security Service (SB), but managed to strike back: on May 1, 1982, a series of anti-government protests brought out thousands of participants—several dozen thousand in Kraków, Warsaw and Gdańsk. On May 3 more protests took place, during celebrations of the Constitution of May 3, 1791. On that day, communist secret services killed four demonstrators – three in Warsaw and one in Wrocław.
Another wave of demonstrations occurred on August 31, 1982, on the second anniversary of the Gdańsk Agreement (see August 31, 1982 demonstrations in Poland). Altogether, on that day six demonstrators were killed – three in Lubin, one in Kielce, one in Wrocław and one in Gdańsk. Another person was killed on the next day, during a demonstration in Częstochowa. Further strikes occurred at Gdańsk and Nowa Huta between October 11 and 13. In Nowa Huta, a 20-year-old student Bogdan Wlosik was shot by a secret service officer. contains an answer for the question: What were the names of the people in the group that was to serve as Solidarity's underground leadership?, what is it ?
