To commemorate today’s 75th anniversary of D-Day, the Library of Congress Blog features D-Day top-secret maps donated by Commander Charles Lee Burwell.

The blog post by LC writer/editor Neely Tucker tells the story of these highly prized maps, according to Burwell and Ryan Moore, a cartographic specialist in LC’s Geography and Map Division,

D-Day Top-Secret Maps

Intelligence forces prepared D-Day top-secret maps for soldiers who would invade Normandy. Tucker writes,

The night before the invasion — dubbed Operation Overlord — Allied Supreme Commander Dwight D. Eisenhower, British General Bernard Montgomery, and other leaders gathered in Portsmouth, a port city on the English Channel, for a last briefing on everything from the weather to the terrain.

U.S. Navy Lt. Commander Charles Lee Burwell, a 27-year-old Harvard graduate, was “scared to death” to present his intelligence to this august gathering. Nevertheless, he delivered a short talk on tides and the thousands of star-shaped steel barbs, called “Czech hedgehogs,” that the Germans had dropped just offshore to wreck landing crafts.

D-Day Top-Secret Maps

The maps used in this briefing contained information that was hard-won. Three-dimensional models of Utah Beach, the code name for beaches near Pouppeville, La Madeleine, and Manche, France, were made of rubber. In two 4×4 sections, the D-Day top-secret maps illustrated the beach and the hedgerow-lined pastures directly in land, “a geographic feature,” Tucker writes, “that obstructed lines of sight and created conditions for deadly, close-quarter combat. Later that night, Burwell took the model aboard transport ships, showing the commanders and troops the same raised maps of the terrain they would see for the first time in a few hours.”

How Top-Secret D-Day Maps Were Made

Both American and British reconnaissance teams, with the assistance of the French Resistance, gathered topographic information and additional data unobservable from photographs and maps. The Navy’s Special Devices Division at Camp Bradford, Virginia, assembled the model. American pilots then flew the completed D-Day top-secret maps back to Portsmouth, where Burwell and others briefed Eisenhower and Montgomery.

“I would have preferred to go on one of those beaches [on D-Day],” Burwell said in his Library of Congress interview. Tucker writes, “[Burwell] recalled the auditorium, that the models were elevated so that they could be clearly seen – and that Montgomery, the legendary British commander, was a dapper dresser. ‘He didn’t look like he was going to battle; he looked like he was going to Greenwich village night club.'”
