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, author of Of Spies and Stratagems. 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 enemy roadways or airport runways.

Historically, caltrops have been found in Babylonian tombs, were used against medieval knights on horseback, and were found in archaeological digs at Jamestown.

    If it works…

    Can’t believe we’ve been using these for thousands of years

      Yeah pretty crazy someone picked up a stick and realized it made a good weapon. Then someone sharpened it and it rocked their whole worldview for ages.

      Simple stuff that’s wildly effective tends to have long reaching effects.

      Mythbusters tested them if you’re curious. In the James Bond car chase episode.

      The vehicle they deployed then against was able to keep chasing them for a long while after running over them.

        Did myth busters make them so that hollow prongs broke off inside the tires? Because that’s how anti-vehicle caltrops are made these days.
