In 1918, Irish Republicans who were locked up in Lincoln Prison began hatching a plan to escape. The internees, among them, Eamon de Valera, had been accused of conspiring with Germany against Britain during the First World War and were imprisoned without trial under what became known as the German Plot. The idea of escape was not so unusual. However, the plan itself was. One of the prisoners, Peter DeLoughry from Kilkenny, decided that the best way to make an escape was, simply, to walk out of the jail. This is what they did.
Declan Dunne, has written a biography of his grand-father, Peter’s Key – Peter DeLoughry and the fight for Irish independence which describes in detail how the escape was planned and executed by using previously unpublished material including contemporary accounts from the prisoners and British secret service documents.
