Dan Snow explains how the idea for using barbed wire for corralling cattle in America’s ‘wild west’ was adapted for use in the Western Front during WW1. We learn about a manual that was produced to instruct soldiers on how to use the wire most effectively. This included information about laying the wire out under cover of darkness to trap or slow down attacking soldiers and to create clear ‘corridors’ so enemy attacks could be ‘directed’.
