Nine days after the Allied landing in Normandy, 297 Royal Air Force bombers raided the port of Boulogne-sur-Mer, one of the seven fortresses of the Atlantic Wall. Their bombs missed their target and razed the city center. It will be the deadliest bombing of war.
From old scanned argentic photos taken on March 22, 1945 during an aerial reconnaissance mission, we were able to model (by photogrammetry) a big part of the city of Boulogne-sur-Mer at the time when much damages are still visible all around the port and the traces of the allied landing are very fresh.
Many thanks to IGN for its archive of aerial photographs, this allows us to immerse ourselves in the past.
