"On December 16, three days after the introduction of the martial law in Poland, pro-Solidarity miners striking against the declaration of the martial law by General Wojciech Jaruzelski were dispersed by the troops of the Polish army and police. The forces used in the main thrust against the miners consisted of eight companies of riot police (ZOMO, supported by ORMO (police reservists) and NOMO) with seven water cannons, three companies of military infantry fighting vehicles (each of 10 vehicles) and one company of tanks. The miners repeatedly fought them off with their tools. During the brawl a number of strikers and 41 troops were injured, including 11 severely.
In the apex of the events, a commando-type special platoon of ZOMO opened the "shoot to kill" fire at the strikers, killing nine of them (Jan Stawisiński, Joachim Gnida, Józef Czekalski, Krzysztof Giza, Ryszard Gzik, Bogusław Kopczak, Andrzej Pełka, Zbigniew Wilk and Zenon Zając) and wounding 21 others.

"The protests were sparked by a sudden increase in the prices of food and other everyday items. Strikes were put down by the Polish People's Army and the Citizen's Militia, resulting in at least 44 people killed and more than 1,000 wounded."
