OHL issues equivocal instruction on role of forthcoming Siegfried Stellung (Hindenburg Line): ‘Just as in times of peace, we build fortresses, so we are now building rearward defences. Just as we have kept clear of our fortresses, so we shall keep at a distance from these rearward defences’.

Eastern Front
Romania: Mackensen reaches Alexandria, 50 miles from Bucharest, and contacts Falkenhayn.
Central Power Aeroplanes bombard Bucharest for five hours, as the Central Power’s armies are only 47 miles away from the Romanian capital.

Southern Front
Macedonia: French and Serbs capture Hill 1,050 (7 miles north-east of Monastir).

Asiatic and Egyptian Theaters
Egypt: East Sinai railway reaches Mazar.
