The following article contains an answer for the question: What was the full name of the committee who put forward 21 demands outside the shipyard's gate on August 17? , can you please find it?   On August 16, delegations from other strike committees arrived at the shipyard. Delegates (Bogdan Lis, Andrzej Gwiazda and others) together with shipyard strikers agreed to create an Inter-Enterprise Strike Committee (Międzyzakładowy Komitet Strajkowy, or MKS). On August 17 a priest, Henryk Jankowski, performed a mass outside the shipyard's gate, at which 21 demands of the MKS were put forward. The list went beyond purely local matters, beginning with a demand for new, independent trade unions and going on to call for a relaxation of the censorship, a right to strike, new rights for the Church, the freeing of political prisoners, and improvements in the national health service.Next day, a delegation of KOR intelligentsia, including Tadeusz Mazowiecki, arrived to offer their assistance with negotiations. A bibuła news-sheet, Solidarność, produced on the shipyard's printing press with KOR assistance, reached a daily print run of 30,000 copies. Meanwhile, Jacek Kaczmarski's protest song, Mury (Walls), gained popularity with the workers.On August 18, the Szczecin Shipyard joined the strike, under the leadership of Marian Jurczyk. A tidal wave of strikes swept the coast, closing ports and bringing the economy to a halt. With KOR assistance and support from many intellectuals, workers occupying factories, mines and shipyards across Poland joined forces. Within days, over 200 factories and enterprises had joined the strike committee. By August 21, most of Poland was affected by the strikes, from coastal shipyards to the mines of the Upper Silesian Industrial Area (in Upper Silesia, the city of Jastrzębie-Zdrój became center of the strikes, with a separate committee organized there, see Jastrzębie-Zdrój 1980 strikes). More and more new unions were formed, and joined the federation.
