Crossword History: Dawe and D-Day

[Image courtesy of Wikipedia.]

June 6, 1944 is a date that will continue to resonate for decades to come, and perhaps centuries. On that day, D-Day, the largest amphibious military attack in history was launched as the Allied forces landed at Normandy. This was one of the major offensives that helped bring about the end of World War II.

But a few days before that, a curious confluence of events brought crosswords to the attention to British agents, namely those of MI5.

Yes, tomorrow, June 2, 1944, marks the anniversary of the day a physics teacher and crossword constructor named Leonard Dawe was questioned by authorities after several words coinciding with D-Day invasion plans appeared in London’s Daily Telegraph newspaper.

More specifically, the words Omaha (codename for one of Normandy’s beaches), Utah (another Normandy beach codename), Overlord (the name for the plan to land at Normandy on June 6th), mulberry (nickname for a portable harbor built for D-Day), and Neptune (name for the naval portion of the invasion) all appeared in Daily Telegraph crosswords during the month preceding the D-Day landing.

So, the authorities had to investigate the highly improbable, yet still possible, scenario that Dawe was purposely trying to inform the enemy of Allied plans, and scooped up the constructor to investigate.

In the end, no definitive link could be found, and consensus is that Dawe either overheard these words (possibly mentioned by the loose lips of soldiers stationed nearby) and slipped them into his grids unwittingly, or this is simply an incredible coincidence.

Some crossword fans suspect that there’s more to the story, though.

According to The Guardian newspaper:

During the celebrations of the 40th anniversary of D-day, one of Dawe’s former pupils approached the Telegraph and insisted that as a lad, he had overheard US and Canadian soldiers discussing the plans, picked up on the codewords, and suggested them to his headmaster as possible entries.

This has been dismissed by most historians as an attempt to rewrite or embellish an already baffling story.

Nonetheless, it’s possible that, somewhere, some document connecting Mr. Dawes and the codewords is waiting to be discovered.

Until then, it simply remains a curious moment in crossword history.

75 Years of New York Times Crosswords!

Yesterday marked the 75th anniversary of The New York Times publishing its first crossword, and I thought I’d delve into NYT crossword history a bit to commemorate this event!

On February 15, 1942, The New York Times ran its first Sunday edition crossword. (The daily feature as we know it wouldn’t come into effect until 1950.)

But, you might be thinking to yourself, Arthur Wynne’s “word-cross” first appeared in the New York World in 1913. Simon & Schuster published The Cross-Word Puzzle Book, edited by Margaret Farrar, in 1924. What took The New York Times so long to catch on?

Truth be told, they didn’t think much of crosswords back then.

“Scarcely recovered from the form of temporary madness that made so many people pay enormous prices for mahjongg sets, about the same persons now are committing the same sinful waste in the utterly futile finding of words the letters of which will fit into a prearranged pattern, more or less complex.”

The article goes on to call crosswords “a primitive form of mental exercise” and compare their value to that of so-called brain teasers that should be solved by schoolchildren in 30 seconds or less. A pretty harsh assessment, overall.

So, what changed their minds regarding crosswords?

Well, World War II happened.

“I don’t think I have to sell you on the increased demand for this type of pastime in an increasingly worried world,” wrote Margaret Farrar, the first crossword editor of The Times, in a memo to Lester Markel, the Sunday editor, after the Pearl Harbor attack. “You can’t think of your troubles while solving a crossword.”

In a memo dated December 18, 1941, Markel conceded that the puzzle deserved space in the paper, considering what was happening elsewhere in the world, and that readers might need something to occupy themselves during blackouts.

The puzzle proved popular, and Arthur Hays Sulzberger — the publisher of the New York Times and a longtime crossword fan himself — would author a Times puzzle before the year was out.

And so now, only a few years after the crossword itself celebrated its centennial, the most famous crossword outlet in the world is celebrating three-quarters of a century, along with a wonderful legacy of innovation, wordplay, and creativity.

To mark the occasion, The Times is going all out. Not only did they publish a crossword on Tuesday by the youngest constructor in NYT history — 13-year-old Daniel Larsen — but over the course of the year, they’ll be publishing collaborations between top constructors and celebrity solvers!

The first, a feast of a collab between Patrick Blindauer and actor Jesse Eisenberg, was published yesterday.

So, we here at PuzzleNation tip our hat to not only the current crew at The New York Times crossword, but all of the editors, constructors, creators, and collaborators who have contributed to a true crossword institution. I, for one, can’t wait to see what they come up with next.

The GCHQ Strikes Again!

Last year, one of the toughest puzzles I encountered all year was the GCHQ Christmas Card.

The GCHQ — Government Communications Headquarters — provides security and intelligence services for the British government. Back when they were known as GC&CS — Government Code and Cypher School — they were responsible for funding Bletchley Park and its successes cracking the German “Enigma” code during World War II.

And last Christmas, they released a puzzly Christmas card that challenged the staunchest puzzlers, with over 600,000 submissions, but only 3 successful solutions!

This year, they’re doing things a little bit differently.

[Click here for a larger version.]

This puzzle is the first step in a larger event that the GCHQ expects will take MONTHS to solve. (Their official due date for submissions is February 28, 2017!)

The big change here is that instead of a series of webpages available free to the public, they’re releasing this puzzly master challenge as a book containing over 140 codes and puzzles.

But it’s for a good cause, as “all GCHQ’s proceeds from sales of the book will be donated to the Heads Together campaign, supported by HRH The Duchess of Cambridge, who wrote the foreword for The GCHQ Puzzle Book.”

The Duchess writes:

I have always been immensely proud of my grandmother, Valerie Glassborow, who worked at Bletchley Park during the Second World War. She and her twin sister, Mary, served with thousands of other young women as part of the great Allied effort to break enemy codes. They hardly ever talked about their wartime service, but we now know just how important the men and women of Bletchley Park were, as they tackled some of the hardest problems facing the country.

In a new century, their successors at GCHQ continue this intellectual tradition. Like their Bletchley predecessors, they have become well known for valuing and understanding the importance of mental wellbeing. This is so important when dealing with such discretion and the pressure which comes with this.

William, Harry and I are very grateful that this book is supporting our Heads Together Campaign. I hope it will not only amuse and challenge readers, but help to promote an open discussion of mental health problems, which can affect anyone, regardless of age or background. Together, we are aiming to change the national conversation around mental health from stigma and fear to openness and understanding. Those who buy this book and support the Heads Together campaign will be playing a part in helping people get the important mental health care they deserve.

Puzzles and charitable works: a perfect holiday match, to be sure.

For US shoppers, the book is available as a Kindle ebook through Amazon.com, but if you want a paperback copy, you’re better off ordering it from Amazon.co.uk. With shipping and conversion, it still cost me less than $20.

The Story Behind Bletchley Park

It’s amazing when you consider the impact one of the most common forms of puzzle solving, cryptography, has had on world history. From the Revolutionary War to World War II, codebreaking was a battlefront as crucial and as exhausting as any contested piece of land on the map.

This was brought into stark clarity recently when I read The Secret Lives of Codebreakers by Sinclair McKay, which chronicles the work and lives of the team members at Bletchley Park who dedicated themselves to cracking the German Enigma code. It’s been said that Bletchley Park’s achievements shortened the war by two or three years. That’s no small feat.

(You know the decryption work done at Bletchley Park was good if it inspired parts of two of Ian Fleming’s James Bond novels. The film The Imitation Game barely scratched the surface.)

From The Secret Lives of Codebreakers:

Here, in these grounds fifty miles to the north of London, they would be introduced to the gravest secret of the war. Every intercepted enemy message — every signal from every captain, commander, military division, battleship, U-boat — all these encrypted communications, jumbled up into seemingly random letters in groups of four and five, and transmitted by radio, were gathered by the many listening posts around the British coastline.

From the Battle of Britain to the Blitz, from Cape Matapan to El-Alamein, from Kursk to the V-1 flying bombs, to D-Day and Japan, the work of Bletchley Park was completely invisible, yet right at the heart of the conflict. It was a key player whose presence, at all times, had to be kept utterly hidden from the enemy.

Imagine working these incredibly intensive sessions, obsessively looking over bits of code for hours at a time, knowing that the fate of the world rested on your shoulders, and a simple transcription mistake could cost lives. It’s a mind-boggling concept.

And the book shed a great deal of light on the decryption work itself. For instance, I had no idea how many variations of the Enigma code they were expected to crack.

The German rule was that no message should be more than 250 letters in length; if it was necessary to send a longer message, it should be split into multiple parts. This was designed to make life more difficult for codebreakers: the longer the message, the easier it might be for such a person to see patterns of letters forming among the apparent chaos.

Thanks to preambles in each Enigma message, codebreakers could at least be organized under different color keys: yellow, green, red, and blue. When they ran out of colors, they named keys after marine life, then birds, then elephants, then insects.

This was a war, and organization was key, no pun intended.

The first big break is known as the Herivel Tip, when one of the Bletchley Park crew deduced that some Enigma machine operators might choose the new day’s settings based on the letters used the previous day. This became a valuable jumping-off point for daily decryption attempts with their own coding device, the bombe machine.

In 1941, the first major Enigma-style code, the Abwehr code, was broken by Bletchley Park. In June of 1941, they broke the Vulture key, which revealed German activity on the Eastern front.

But the Germans were constantly adapting and refining their codes. German paranoia led to submarines using a different code than surface naval vessels. So “Dolphin,” the surface naval code, was not the only code troubling Bletchley Park. “Shark,” the submarine key, was a new concern. Thankfully, when U-559 sank in 1942 and its crew abandoned ship, its Enigma machine and a book of current “Shark” keys was salvaged by Allied forces without German knowledge.

In 1943, they broke “Porcupine,” giving them access to all German air force messages for a few weeks.

Around this time, the German High Command began using another method to transmit encrypted messages, and this became yet another focus of Bletchley Park. The “Fish” or “Tunny” communications were between generals and the Fuhrer himself.

This led to the development of the big brother of the bombe machine, Colossus, which combined the logic engines of a Turing machine with electronic valves that allowed it to read 5000 characters a second, five times faster than the previous top machine.

(While this was going on, Turing himself was developing a new speech encipherment system, Delilah, so named because she was a deceiver of men.)

In January 1945, efforts were still going strong, as Bletchley Park not only cracked the “Puffin” and “Falcon” keys of the German army, but effectively countered attempts by the Luftwaffe to implement new encryptions. By this point, dozens of variations of Enigma had been unraveled by the team.

Of course, decryption wasn’t the only thing accomplished at Bletchley Park.

The grand deception that led to the Normandy invasion was also managed there. They gradually fed false data to German Intelligence about military groups like the First United States Army Group preparing to enter France via the Pas de Calais and the Twelfth British Army into Scandinavia and Turkey. This allowed for D-Day to proceed, as German attention was diverted.

But The Secret Lives of Codebreakers goes beyond their wartime victories. McKay takes us behind the scenes of Bletchley Park to share not only the hard-won achievements of the cryptographers there, but also what daily life was like on the isolated estate. From living conditions and several romances to rivalries and petty feuds caused by high tensions, the book catalogues the realities of such stressful work in richly detailed fashion.

I think my favorite discoveries were related to the off-time of the recruits:

Oliver and Sheila Lawn have especially fond memories of the way that Bletchley-ites contrived to use their leisure time: “There was music,” says Mr. Lawn, “Play readings. And play actings. Quite a bit of amateur dramatics. And concerts of all kinds.”

Highland dancing, madrigals, creating palindromes…they were offered all sorts of activities to help keep spirits up after grueling decryption sessions. Certain musical artists were even invited up to perform there!

When you consider how important their work was and how many years they were sworn to silence about Bletchley Park, these revelations become all the more stunning. This isn’t just a fascinating work of puzzle history, this is history itself.

It’s Follow-Up Friday: Cinematic Crossword Codecracking edition!

Welcome to Follow-Up Friday!

By this time, you know the drill. Follow-Up Friday is a chance for us to revisit the subjects of previous posts and bring the PuzzleNation audience up to speed on all things puzzly.

And today, I’d like to revisit one of my favorite puzzle constructors, David Kwong!

[Check out David’s session of 5 Questions here.]

Not only is he a topnotch constructor, he’s also a magician who performs his own signature tricks while consulting for film projects and television shows. He’s worked on The Mindy Project, The Incredible Burt Wonderstone, and Now You See Me (as well as the upcoming sequel).

And his latest collaborative efforts just hit theaters yesterday in The Imitation Game, the Benedict Cumberbatch/Keira Knightley film detailing Alan Turing’s efforts at Bletchley Park to break the infamous German Enigma Code during World War II.

But it was David’s crossword skills on display this time around, as he constructed the crossword Alan Turing uses in the film to test potential cryptographers in the movie.

I don’t have that crossword for you to solve, unfortunately, but thanks to The New York Times and Deb Amlen’s Wordplay blog, I can offer you a link to an actual crossword Alan Turing created for The Telegraph.

Plus, the official website for The Imitation Game has a puzzle you can solve to unlock exclusive content. (Just click the link and then click “Crack the code” in the lower right-hand corner of the screen.)

The film is already being hailed as one of the best of the year. I can’t wait to see what David works on next.

A revolution in puzzles?

Crosswords have certainly changed the world. They’re the most popular puzzles in history, challenging the minds of millions every day and kickstarting a pencil-and-paper puzzle revolution in the process. Heck, they’ve even been used in England as part of the recruitment process for code breakers and other puzzly government positions!

But did you know that some constructors have been accused of trying to bring about actual revolutions with crosswords?

Oh yes! The Venezuelan newspaper El Aragueno has been accused on several occasions of hiding encrypted messages within their daily crossword puzzles in order to incite revolt against the government. (And a year ago, another Venezuelan newspaper, Ultimas Noticias, was accused of concealing messages ordering the assassination of a public official!)

While there are no details on what the incendiary message secretly contained within El Aragueno’s puzzle might have said, this isn’t the only time crosswords and constructors have run afoul of the powers that be.

Back in June of 1944, physics teacher and crossword constructor Leonard Dawe was questioned by authorities after several words coinciding with D-Day invasion plans appeared in London’s Daily Telegraph.

The words Omaha (codename for one of Normandy’s beaches), Utah (another Normandy beach codename), Overlord (the name for the plan to land at Normandy on June 6th), mulberry (nickname for a portable harbor built for D-Day), and Neptune (name for the naval portion of the invasion) all appeared in Daily Telegraph crosswords during the month preceding the D-Day landing.

So it was possible (though highly improbable) that Dawe was purposely trying to inform the enemy of Allied plans, and the powers that be acted accordingly. (In the end, no definitive link could be found, and consensus is that Dawe either overheard these words, possibly slipped by soldiers stationed nearby, and slipped them into his grids unwittingly, or this is simply an incredible coincidence.)

Either way, it just goes to show you how influential crosswords have been (and could be!) over the last hundred years.
