After distinguishing himself on the battlefields of the First World War, Major-General Sir Hugh Tudor could have sought a respectable retirement in England, his duty done. But in 1920, his old friend Winston Churchill, Minister of War in Lloyd George’s cabinet, called on Tudor to serve in a very different kind of conflict—one fought in the Irish streets and countryside against an enemy determined to resist British colonial authority to the death. And soon Tudor was directing a police force waging a brutal campaign against rebel “terrorists,” one he was determined to win at all costs—including utilizing police death squads and inflicting brutal reprisals against IRA members and supporters and Sinn Féin politicians.
