- Overnight the Russian forces opposite the left wing of the German 11th Army withdraw to a new defensive line running through Ruda Rozaniecka and Plazow, but this evening the Austro-Hungarian 11th Division, on 11th Army's western flank, seizes the latter village this evening.
- After the capture of Amara on the Tigris River earlier this month, the Indian corps in lower Mesopotamia has turned its attention to the Euphrates, as 12th Indian Division has been ordered to advance upriver and seize Nasiriyeh. Hammar Lake, en route to Nasiriyeh, is notoriously shallow, and to traverse it has required the assembly of a curious flotilla of shallow-draught stern-wheelers and tugs, and in a neat bit of imperial symmetry the former had been originally constructed in 1884 for service on the Nile with the Gordon relief expedition. After numerous groundings the vessels reach the western exit of the lake at Akaika today, only to find it blocked by a barrier of vessels sunk by the Ottomans. The expedition halts as dynamite is brought up from Basra to blast their way through.

- In German South-West Africa, the main German force falls back along the railway to the northeast to Otavi today, fearing that otherwise the South Africans will outflank them. Here the Germans intend to make a stand, forcing the enemy to fight their way through and hopefully buying time to erect further defensive positions to the rear.
