In February 1981, Defense Minister General Wojciech Jaruzelski assumed the position of prime minister. The Solidarity social revolt had thus far been free of any major use of force, but in March 1981 in Bydgoszcz three activists were beaten up by the secret police. In a nationwide "warning strike" the 9.5-million-strong Solidarity union was supported by the population at large, but a general strike was called off by Wałęsa after the 30 March settlement with the government. Both Solidarity and the communist party were badly split and the Soviets were losing patience. Kania was re-elected at the Party Congress in July, but the collapse of the economy continued and so did the general disorder.
