On 13 of December in London, small group of polish language anarchists gathered around the "Builder Memorial" on Tower Hill.Reason for that, was 30' anniversary of forced martail law by state communist regime in Poland. Symbolic meeting with posters and lightened candles was held in memory of 122 killed workers and around 10 000 detained in special camps. All strikes and demonstrations were brutally crushed by polce and army, so called "workers gowernment" used tanks and guns against striking workers. Government afraid of growing grass root union "Solidarity" (at least it was on that time) and other rank and file organisations used martial law to supress oposition.

In the deadliest incident, nine people were killed by ZOMO paramilitary police whilst breaking a strike action in "Wujek" Coal Mine on December 16, 1981. People were also killed and wounded during a massive wave of demonstrations which took place on August 31, 1982. People were often tortured, and union activists often dissapeared without trace.
