How a British Scientist Turned 200 German Mines Into Booby Traps That Killed Their Own Engineers

In 1942, a quiet British scientist working from a rented building in Cairo did something that terrorised an entire corps of German engineers — he made their own expertise into a weapon against them. By fitting an invisible secondary fuze inside standard British mines, Millis Jefferis ensured that the more carefully a German engineer followed his training, the more certainly he would die. This is the story of the most dangerous trap of the Western Desert Campaign — one that fit inside a tin, cost almost nothing, and changed the battle for North Africa. #WW2History #NorthAfrica #ElAlamein #SecretWeapons #ww2engineering This content is produced for historical education and documentary purposes only.
