The secret role of Beaumanor Hall

The Leicester Mercury reports on the top secret wartime listening station role of a Leicestershire mansion

As we approach the 75th anniversary of VE Day in May, a Loughborough Library Local Studies Volunteer (LLLSV) tells the fascinating story of Beaumanor Hall’s crucial role in the Second World War.

Many readers may not know, but Beaumanor Hall was the site of a vital wartime intelligence service, namely the War Office “Y” (wireless) Group or W.O.Y.G.

The top secret “Y” Group was part of M18 Wireless Intelligence and Beaumanor was a highly-strategic “Intercept Station”, concerned with monitoring the enemy’s main channels of wireless traffic and communications.

The “Y” Intercept Listening Service operated from 1941 to 1945 and its wartime activities were as top secret as those at the Code and Cypher School at Bletchley Park.

The WWII “Mosquito Network”

Inside the U.S. effort in a battle of the airwaves during the Pacific campaign of World War II

We can’t fully appreciate the importance of news from home to those who served in World War II. In the Pacific campaigns, G.I.s, sailors and Marines fought bloody island-hopping battles; as each island was cleared, garrison troops and hospitals moved in and carried on their own war against mosquitoes, isolation and boredom. The island fighters were fortunate if dated mail caught up with them before they moved on to the next target. Timely personal-level communications were pretty much absent.

Radio programming from America was available but only on shortwave. And shortwave radios were not generally available. The fortunate few had been issued “Buddy Kits” that included a radio, a small PA system and a record player for discs sent by mail. But for most there was no way to receive short-lived information such as news and sports. They were left with enemy radio propaganda such as Japan’s “Orphan Ann/Annie” (aka one of several Tokyo Roses) and the “Zero Hour” program.

No wonder that the idea of having a local island radio station doing “live from home” was so fiercely supported. Enlightened commanders saw the idea as a terrific morale-builder. The only problem was how to pull it off.

A solution, not uniquely, came from within the ranks. It started with the work of some bored but talented soldiers in the Panama Canal Zone who in 1940 built a couple of 50 W transmitters and put them on the air without authorization, labeling them “PCAN” and “PCAC.”[…]

An Enigma machine just fetched over $106K at auction

(Source: Bloomberg.com)

A rare “Enigma” machine, used by Nazi Germany to create military communications code thought to be unbreakable, sold at auction for more than $106,000.

The 28.5-pound cipher machine went to an internet buyer on Saturday, according to Heritage Auctions. It comes with operating instructions, a case with an engraved Third Reich emblem — and a rich lore including how British scientist Alan Turing helped crack the code.

One of the unit’s 26 light bulbs is broken, according to the description.

It’s not the first time a Nazi code creator has traded hands for such a sum. In May, an Irish private collector swiped up a different encryption machine, known as the “Hitler mill” because of its hand crank, for 98,000 euros ($109,000) from a Munich auctioneer, according to the Telegraph.[…]

SWLing Post contributor and friend, Dan Robinson, and I once visited the National Cryptological Museum at Fort Meade and got to try our hand at using an Enigma machine. It’s an absolutely brilliant bit of mechanical engineering, of course. I highly recommend this museum to anyone interested in radio, computers or cryptography.

If you’d like to learn about another fascinating bit of over-the-air WWII technology–the SIGSALY network–I strongly encourage you to check out this post from our archives.

“BBC’s secret World War Two activities revealed”

4 Replies

Many thanks to SWLing Post contributors Fred Waterer and Mike Hansgen who share the following article from the BBC:

A new archive has revealed the BBC’s role in secret activities during World War Two, including sending coded messages to European resistance groups.

Documents and interviews, released by BBC History, include plans to replace Big Ben’s chimes with a recorded version in the event of an air attack.

This would ensure the Germans did not know their planes were over Westminster.

BBC programmers would also play music to contact Polish freedom fighters.

Using the codename “Peter Peterkin”, a government representative would provide staff with a particular piece that would be broadcast following the Polish news service.

Historian David Hendy said: “The bulletins broadcast to Poland would be deliberately short by a minute or so and then a secret messenger from the exiled Polish government would deliver a record to be played.

“The choice of music would send the message to fighters.”[…]

A simple WWII era “hack proof” way to send messages between ships

U.S. NAVY PHOTO BY MASS COMMUNICATION SPECIALIST 1ST CLASS BRIAN P. CARACCI (via Popular Mechanics)

Many thanks to SWLing Post contributor, Marty, who writes:

Hi Thomas, I spotted this article in Popular Mechanics – To Prevent Cyber Snooping, The US Navy is Relying on WWII-Era Communications – and of course I thought it was about short wave. Boy, was I wrong!

(Source: Popular Mechanics)

The U.S. Navy, anticipating a future when a high-tech enemy could read its electronic communications, is going back to a hack-proof means of sending messages between ships: bean bags. Weighted bags with messages inside are passed among ships at sea by helicopters.

In a future conflict with a tech-savvy opponent, the U.S. military could discover even its most advanced, secure communications penetrated by the enemy. Secure digital messaging, voice communications, video conferencing, and even chats could be intercepted and decrypted for its intelligence value. This could give enemy forces an unimaginable advantage, seemingly predicting the moves and actions of the fleets at sea with uncanny accuracy.

Last week, a MH-60S Sea Hawk helicopter delivered a message from the commander of an amphibious squadron to the captain of the amphibious assault ship USS Boxer. The helicopter didn’t even land to deliver it, dropping it from a hovering position before flying away. The message was contained in a bean bag dropped on the Boxer’s flight deck.

The bean bag system, as Military.com explains it, is nearly eight decades old. The system dates back to April 1942, when a SBD Dauntless dive bomber assigned to the USS Enterprise was flying a scouting mission ahead of the USS Hornet. Hornet, about to launch sixteen B-25 Mitchell bombers on a raid against Japan, was traveling in extreme secrecy to preserve the element of surprise. The Dauntless pilot encountered a Japanese civilian ship and, fearing he had been spotted, dropped a message in a bean bag on the deck of Hornet. You can see some archival footage of the event here.[…]

Alan Turing: “New face of the Bank of England’s £50 note”

Many thanks to a number of SWLing Post readers who sent a link to this piece from the BBC News:

Computer pioneer and codebreaker Alan Turing will feature on the new design of the Bank of England’s £50 note.

He is celebrated for his code-cracking work that proved vital to the Allies in World War Two.

The £50 note will be the last of the Bank of England collection to switch from paper to polymer when it enters circulation by the end of 2021.

[…]”Alan Turing was an outstanding mathematician whose work has had an enormous impact on how we live today,” said Bank of England governor Mark Carney.

“As the father of computer science and artificial intelligence, as well as a war hero, Alan Turing’s contributions were far-ranging and path breaking. Turing is a giant on whose shoulders so many now stand.”[…]
