June 1940. Britain's Spitfires are winning the Battle of Britain in the skies, but on the ground, a secret crisis threatens to destroy everything. The nation has run out of graphite—the critical lubricant keeping aircraft engines, tanks, and weapons running. Without it, ball bearings seize up, production stops, and the war effort grinds to a halt.
In a desperate move, the government raids every pencil factory in Britain. Coal miners are pulled from the pits to extract graphite from pencil lead, factory waste, even pencil shavings from schoolrooms. Working 24-hour shifts in secret facilities, covered in black dust, these forgotten heroes processed 300 tons of materials to keep Britain fighting.
This is the incredible true story of how pencil lead nearly lost—and ultimately helped win—World War II.
