Author and historian Fraser Skirrow talks about raiding on the Western Front during the First World War.

Once the frontline became static and dominated by trenches, barbed wire and artillery, a new form of operation emerged, raiding. Trench raids aimed at forcing temporary entry into the enemy’s line in order to kill defenders, destroy fortifications and weapons, gain intelligence by the capture of maps and documents, and return with prisoners. Fraser talks about how this new type of warfare emerged and developed over the course of the war.
