Defence of the Realm Acts
German spies that were caught in the UK during World War One (1914-8) were dealt with under various sections of the Defence of the Realm legislation. It was for acts committed under this law, that the leaders of the Irish Easter Uprising were courts-martialled. Roger Casement, who was tried and executed in 1916, was tried under the High Treason Act.
The condemned spies were shot by firing squad either in the old miniature rifle range in The Tower of London or The Tower's ditch. The rifle range was demolished for office space in 1969, and later converted into car-parking space. All the executed spies were buried in East London Cemetery, in Plaistow, London.
The following table list the people executed by firing squad at the Tower of London during World War One. Those people whose trial records I have examined, have their own page (list on the left-hand side).
