Loch Long Torpedo Range c. 1920

A Torpedo Range has existed on Loch Long since 1912, and was the scene of an unusual espionage story in 1915, which ended with an execution at the Tower of London.

Born in 1881, Augusto Alfredo Roggen (Uruguyan) sailed from Rotterdam to Tilbury Docks in May, 1915. From there he made his way to Edinburgh, posing as a farmer, and on to Tarbet, arriving in June and taking a room at the hotel of the same name. Arrested within 5 hours of his arrival, he had purchased a map of the local area, including Loch Long, site of the Admiralty Torpedo Range. Police found a revolver, ammunition, invisible ink, and a contact list in his room.

Transported London, he gave no statement or evidence at his courts-martial, and was found guilty He was sentenced to death by shooting in August, 1915.

The sentence was carried out at 6 am, September 17, 1915, at the Tower of London, by men of the 3rd Battalion, Scots Guards.

A First World War German spy was caught in the Helensburgh district and executed at the Tower of London in 1915.

The fate of Augusto Alfredo Roggen, who was a long way from being a James Bond but paid the ultimate penalty for espionage after being arrested at the Tarbet Hotel, is an extraordinary story.

Augusto was born in Montevideo in 1881, the son of a German who became a Uruguyan citizen four years later, and when he grew up he married a German lady. Described as small, dark, neat and dapper, he did not look German, and he had developed a good command of English.

The mission which was to lead to his death began when he sailed from the Dutch port of Rotterdam on the Batavia, arriving at Tilbury Docks on May 30, 1915. He was interviewed by the Aliens Officer, and he told him that he intended to travel to Scotland. This was allowed, and he arrived in Edinburgh on June 5.

On his way he visited agricultural suppliers in London and Lincoln, claiming to be farmer on business, but those he spoke to thought him patently ignorant of the subject, and he appeared to have no references. When registering at the Carlton Hotel in Edinburgh, he again indicated that he was a farmer and said he was interested in agricultural vehicles.

The following day he registered with the police and, rather oddly, told the officers that while in Germany he had been under suspicion as a spy and was kept under surveillance.

That same day he asked the hotel manager's wife about going around the Trossachs and the availability of local hotels. He went there on a day's outing, but on his return said that he preferred to travel to Tarbet where he intended to stay and fish. He had no fishing gear, but it was often possible to hire tackle, especially for sea fishing.

Before leaving the capital, he sent two postcards to H.Flores, Binnenweg 127, Rotterdam. They were both intercepted, as they had been sent to an address familiar to the security services. They were copied, then allowed to carry on their postal journey, but the authorities now began to take a close interest in his activities.

Augusto was not aware of this when he booked into the Tarbet Hotel on June 9. He bought a map of Loch Lomond and the head of Loch Long — and Loch Long was a restricted area where fishing was banned. Nearby Succoth was also the home of the Royal Navy torpedo testing range.

The authorities were extremely worried about Augusto's presence on Loch Lomondside, so within five hours of his arrival at the picturesque hotel at the junction of the Arrochar and Crianlarich roads, there was a dramatic police swoop led by Superintendent John Wright of Helensburgh Police.

He was immediately arrested, and a search of his room revealed damning evidence — a loaded Browning revolver with 50 rounds of ammunition, invisible ink, and contacts details.

Perhaps not surprisingly, the Helensburgh and Gareloch Times did not report the incident at the time, presumably because of wartime censorship, but they did refer to it after the war, referring to Augusto as “a dangerous type”.

Events moved swiftly after the arrest. Superintendent Wright escorted the prisoner to London, where he and his luggage were handed over to Inspector Edmund Buckley of Special Branch at Scotland Yard. He was unable or unwilling to explain the postcards sent to known enemy espionage addresses.

He was tried by a court martial at Middlesex Guildhall in Westminster on August 20, before the president, Major General Lord Cheysmore. He gave no evidence, made no statement, was found guilty, and was sentenced to death by shooting.

An appeal for clemency was received at the War Office from the Uruguyan Ambassador, and in the interests of diplomacy it was thought prudent to delay the execution and give the representation due consideration. However it was concluded that there was nothing in the note of appeal which would warrant a different course of action.

This remarkable tale of a spy whose relatively insignificant activities achieved absolutely nothing and for which he was to pay with his life was concluded at 6 a.m. on September 17 1915 at the Tower of London.

Augusto Alfredo Roggen was shot by a firing squad composed of men from the 3rd Battalion, Scots Guards. Observers considered that he faced his death as a brave man, marching to the chair with a defiant air and bearing, and refusing to have his eyes blindfolded.
