Although Naguib headed the RCC and Mahir the civilian government, Nasser was the real power behind the RCC. The years between 1952 and 1954 witnessed a struggle for control of the government that Nasser ultimately won. The first crisis to face the new government came in August 1952 with a violent strike involving more than 10,000 workers at the Misr Company textile factories at Kafr ad Dawwar in the Delta. Workers attacked and set fire to part of the premises, destroyed machinery, and clashed with the police. The army was called in to put down the strike; several workers lost their lives, and scores were injured. The RCC set up a special military court that tried the arrested textile workers. Two were convicted and executed, and many others were given prison sentences. The regime reacted quickly and ruthlessly because it had no intention of encouraging a popular revolution that it could not control. It then arrested about thirty persons charged with belonging to the outlawed Communist Party of Egypt (CPE). The Democratic Movement for National Liberation, a faction of the CPE, reacted by denouncing the regime as a military dictatorship.
