Theobald von Bethmann-Hollweg's Address to the Reichstag on the German Policy of Unrestricted U-boat Warfare, 31 January 1917

I have added this speech on why Germany decided on unrestricted submarine warfare in WW I.
It can be found in the Military Stories page of the website
http://www.militaryhistoryofthe20thcentury.com/  and it goes along with the History of German U-boats in WW I.
