Bangalore Torpedo - in World War I

In World War I

By the time of World War I the Bangalore torpedo was primarily used for clearing barbed wire before an attack. It could be used while under fire, from a protected position in a trench. The torpedo was standardized to consist of a number of externally identical 1.5 m (5 ft) lengths of threaded pipe, one of which contained the explosive charge. The pipes would be screwed together using connecting sleeves to make a longer pipe of the required length, somewhat like a chimney brush or drain clearing rod.

A smooth nose cone would be screwed on the end to prevent snagging on the ground. It would then be pushed forward from a protected position and detonated, to clear a 1.5 m (5 ft) wide hole through barbed wire. An example of this technique can be seen in the silent film Wings, the 1927 film that received the Academy Award for Best Motion Picture. During the 1917 Battle of Cambrai, British Royal Engineers used them as diversions to distract the enemy from where the real battle was to be fought.
