Historian Dr Graham Kemp’s presentation introduces the essential differences between U- boats and submarines and examines the different kinds of U Boats used in the First World War. He then looks at how Germany first planned to use them and how they, almost by accident, developed them into a deadly raider. The talk will then cover the U boat Commerce campaign of 1917-18, its aims, hopes and intentions, before explaining why it was doomed to inevitable failure, and huge cost that Germany paid for that failure. Dr Kemp is an experienced speaker, and his passion is getting across the human perspective and experience in his talks. Therefore, the second part of the presentation will examine the actual experiences of the crews serving in the boats, what it was like to serve in them, the danger, the humour, and is drawn from the very few accounts ever written by their crews.
