Military Code Words for the D-Day Invasion Were Hidden in a Crossword Puzzle
Robert F. Sargent
There's no questioning the fact that World War II's D-Day invasion is one of history's most recognizable events -- after all, the Dieppe Raid never landed itself a Spielberg blockbuster (it was more along the lines of a Monty Python skit). So it's not unusual that, back in 1944, U.K. newspaper the Telegraph's daily crossword puzzle featured "Utah" -- the now-famous code name for the beach invaded by the 4th U.S. Assault Division -- as one of its solutions.
But here's the thing: The code word wasn't famous at the time, as that puzzle was published a full month before the Normandy landings.
Weirder still, Utah wouldn't even become a state until 1973.
Still, you could chalk that up to coincidence, right? Sure you could ... right up until, less than three weeks later, another crossword featured a solution of "Omaha" -- aka "the code for the beach to be taken by the 1st U.S. Assault Division." Then, five days after that, it was "overlord" -- the code name for the entire D-Day operation. Three days after that, it was "Mulberry" -- the floating harbors that puked streams of soldiers onto the beaches of Normandy.
Finally, on June 1, 1944 -- still five days before D-Day -- came "Neptune," the aptly named naval assault phase of the invasion. And that, ladies and gentlemen, is when the bright red phone at MI5 headquarters started ringing off the hook.
Possibly because forcing crossword puzzlers to come up with "bivouac" is a war crime.
When MI5 agents stormed the home of Telegraph crossword compiler Richard Dawe and gave him the ol' once over (we're picturing lots of harrumphing accentuated by billy clubs), they soon left ... puzzled. The whole thing seemed to be an inconceivably unlikely coincidence. And that puzzlement lasted 40 years, until Ronald French finally stepped forward with an explanation for the seemingly prophetic crossword clues. You see, Dawe was also a school headmaster (apparently designing crossword puzzles isn't exactly lucrative), and he sometimes had students populate the words into blank crossword patterns, presumably as some kind of sadistic detention punishment. Ronald French was one of said students, and when he wasn't spending time in Dawe's study slaving over crossword grids, he was hanging out with the Allied troops stationed nearby, just, you know, driving tanks and shit.
French was obsessed with the soldiers' activities and sponged up their banter like ... well, like a 14-year-old boy who got to play soldier with actual freaking soldiers. The code words found their way out of the terrifying maze that is a pubescent boy's psyche and into the crossword. And that, kids, is how what at first appeared to be the work of a Nazi spy using a convoluted crossword puzzle plot to snitch valuable wartime information to his superiors instead turned out to be a clever Easter egg inserted by a random teenager.
