Arthur Griffith estimated that in the first 18 months of the conflict, British forces carried out 38,720 raids on private homes, arrested 4,982 suspects, committed 1,604 armed assaults, carried out 102 indiscriminate shootings and burnings in towns and villages, and killed 77 people including women and children. In March 1920, Tomás Mac Curtain, the Sinn Féin Lord Mayor of Cork, was shot dead in front of his wife at his home, by men with blackened faces who were seen returning to the local police barracks. The jury at the inquest into his death returned a verdict of wilful murder against David Lloyd George (the British Prime Minister) and District Inspector Swanzy, among others. Swanzy was later tracked down and killed in Lisburn, County Antrim. This pattern of killings and reprisals escalated in the second half of 1920 and in 1921.
