Caltrop (Tire Spike)

Artifact Details

Caltrops were typically placed on roadways to slow attacking troops traveling by vehicle or animal.

The caltrop was “the simplest weapon we ever made,” according to Dr. Stanley Lovell, the Director of the Research & Development Branch of the Office of Strategic Services (OSS).

Caltrops were typically placed on roadways to slow attacking troops traveling by vehicle or animal. No matter how the caltrop is tossed, it will land with one of its four prongs up. Whatever rolls over it will be punctured or injured. It is effective when many are scattered onto the battlefield, enemy roadways, or airport runways.

Historically, caltrops were used against medieval knights on horseback, and found in archaeological digs at Jamestown. During World War II, OSS operatives developed and deployed classically designed caltrops.

Although our museum is not open to the public, we regularly share new artifacts to give you a virtual peek inside.
