In 1913, the WSPU's campaign became much more violent. They increased their destruction of public and private property. When the women responsible for these actions were caught and placed in prison they immediately commenced hunger strikes. Before the introduction of the Prisoner's Temporary Discharge Act (later to become known as the Cat and Mouse Act) the women were force-fed. After the introduction of the Act, the women were released when they became to weak from hunger and then re-arrested when they had regained their strength.
