War at Sea: Scotland's Story

The Battle of the U-Boats (1x2)

Exibido em:: Abr 14, 2015

In April 1917, German U-Boats were sinking a dozen British ships every day. The First Sea Lord, Jellicoe, warned that Britain might not be able to carry on fighting into 1918. In the second of this two part series, David Hayman explores Germany's World War One U-Boat threat, and the fascinating and dastardly ploys Britain used against the submarines.
