Bernard Frederick Trench

Captain Bernard Frederick Trench (17 July 1880 – 10 October 1967) was a British soldier and famous spy who was caught and convicted by the German authorities just a few years before World War I. In 1913 he was released as a present to Ernest Augustus, Duke of Brunswick, when Ernest married the German Kaiser's daughter, Princess Victoria Louise of Prussia.

Background Trench was a descendant of Lord Ashtown and of Archbishop Trench.

Career Trench was commissioned a second lieutenant in the Royal Marine Light Infantry on 1 January 1899, and promoted to lieutenant on 1 January 1900.

In 1909, Trench served as a lieutenant on HMS Cornwall (1902). With Lieutenant Vivian Brandon (whom he would be arrested also with in 1910 on espionage), he conducted covert reporting ashore of fortifications and beaches in the Baltic. He was an agent of the spymaster and future first director of what would become the Secret Intelligence Service (SIS), also known as MI6, Mansfield Smith-Cumming. Trench's codename was COUNTERSCRAP. In letters, he claimed that he did not intend to commit suicide or escape. Trench's letters, however, condemned Captain Lux, a French officer who escaped from the fortress during Trench's imprisonment. Trench complained that the lax security at the fort was possible because of a promise from the prisoners not to attempt to break out.

Captain Trench and another British subject caught spying, Captain Bertrand Stewart, were pardoned and released by the German Kaiser as a present to Ernest Augustus, Duke of Brunswick when Augustus married the Kaiser's daughter, Princess Victoria Louise of Prussia. (They married on 24 May 1913).

He fought in the Second World War and married Mary Audrey Taylor, daughter of Reverend Robert Fetzer Taylor, on 8 September 1943.
