The gist of this account about maps (and other items useful for escape efforts) being smuggled to Allied POWs during World
The general outline of the scheme to smuggle escape aids to POWs through specially manufactured Monopoly kits is recounted (among other places) in The Game Makers, a 2004 history of the Parker Brothers game company:
When allied airmen began to risk their lives flying missions over occupied Europe, Parker Brothers’ English partner found a way to use the Monopoly game to come to the aid of those who were captured by the Germans. The British War Office worked with a select group of Waddington staffers to modify Monopoly boards for insertion in games that the Red Cross would deliver to Allied prisoners of war. These men carved out precise depressions in the unfinished game boards and, before applying their labels, filled them with low-profile compasses, files, and maps that depicted escape routes from the prison camp where each game was to be sent. (The maps were printed on silk because silk did not rustle when opened. Waddington’s had perfected this process to such an extent that virtually all British flyers climbed into their warplanes with a Waddington’s map secreted in the heel of one of their boots.) Hidden among the games’ play money was real
currency — German,Italian, or Austrian. It is not known how many airmen escaped thanks to these Monopoly games.
Regardless of when it may have been officially declassified, information about the rigged Monopoly kits was openly acknowledged and discussed long before 2007. A 1985 Associated Press article, for example, reported that:
Waddingtons, which received the license to distribute Monopoly in Britain in 1935 from Parker Brothers in the United States, got involved in aiding the prisoners of war because of its printing expertise. It printed maps for the military on durable silk.
Thousands of fliers who went on missions over German-occupied Europe had the maps sewn into their uniforms if they were shot down and captured.
Victor Watson, chairman of the firm, said Waddingtons had a secret department that put the maps, files and money in shallow recesses on the board under the paper face. Then
MI-9,the division of Military Intelligence devoted to helping POWs escape, smuggled the sets into prison camps as recreational equipment.
Powell Davies, who was a 19-year-old flier when he was captured, said the prison escape committees would destroy the sets after removing the escape aids to keep the guards from figuring out what was going on.
Although the account claims “an estimated one-third [of escaped POWs] were aided in their flight by the rigged Monopoly sets,” both the Game Makers excerpt quoted above and Waddington’s chairman said the number of POWs who were actually aided by the smuggled game kits is unknown:
Maps, files and compasses were hidden in Monopoly sets and smuggled into World
War IIGerman prison camps to help British prisoners of war escape, the game’s manufacturer, the John Waddington company of Leeds, England, says. Monopoly boards were made with maps hidden in them showing “escape routes from the particular prison to which each game was sent,” chairman Victor Watson said. “Into the other side of the board was inserted a tiny compass and several fine-quality files.” The money piles were real money, with one piece of Monopoly money on the top and bottom of the pack. “We are not sure how many prisoners were able to escape by this method,” Watson said, but the company likes to think a few did.
A former archivist with John Waddington also pointed out some discrepancies in the account in response to a 2007 London Times recounting of it:
Sir, I write as the former archivist for John Waddington, the company which made Monopoly during the Second World War.
In his article about Monopoly, Ben Macintyre states that the special sets of Monopoly were sent to prison camps via the Red Cross. Waddingtons produced many escape aids which were sent to the Nazi prison camps, but these were always sent via private, often fictitious, organisations like the Licensed Victuallers Prisoner Relief Fund. No escape aids were enclosed in the Red Cross parcels, so that the Germans would have no justification for stopping these much needed parcels from reaching the prisoners.
It is untrue that safe houses were shown on the maps, as there was a virtual certainty that some of the maps would fall into German
hands — theGermans were not fools when it came to tracking down prisoners’ ruses.
