Diary for Sunday, December 26, 1915:
North Sea: Disguised raider Möwe (Dohna-Schlodien) leaves Bremen, bluffs her way through Northern Patrol. On January 16 she captures British liner Appam (£2m cargo plus governors of Sierra Leone and Nigeria) north of Madeira, puts prize crew aboard, arrives Norfolk, Virginia on February 1. Möwe returns to Bremen on March 4, 1916 having sunk 14 ships (11 British) with 57,520 tons.
Germany: Berlin pays Dr Helphand 1 million roubles for Petrograd propaganda, after its Copenhagen ambassador Brockdorff-Rantzau convinced on December 6 that only revolution can remove Russia from Allies.
