World War One Diary for Saturday, January 27, 1917:
Sea War
Germany: U-boat leader Bauer orders his commanders ‘… unrestricted U-boat warfare is to force England to make peace and thereby decide the whole war. Energetic action is required and above all rapidity of action … expend only one torpedo on each ship stopped …’. Dover Straits route now compulsory to maximize time on station.
Western Front
Somme: British take position near Le Transloy and capture 350Â strong garrison.
Politics
Japan: Government asks Britain to approve her assuming German rights in China (done February 16).
