|British dead at Neuve Chapelle, March 12th, 1915.|
- The second advance towards Prasnysz by the German forces under General Gallwitz is called off today north of the town, as Russian counterattacks have checked German momentum.
- In the central Carpathians, General Brusilov continues the counterattack against the left wing of the Austro-Hungarian 2nd Army, and today 34th Division is forced back. The commander of the Austro-Hungarian 2nd Army, meanwhile, is concerned about a Russian breakthrough that would undue what little has been accomplished to date, and rushes his reserves to XIX Corps in front of Lupkow. Further east, the grinding Austro-Hungarian advance towards Baligrod continues - the village of Rabe and the Manilowa Heights are seized today.
- This afternoon a small English gunboat thoroughly searches Isa Bay, from which Emden's landing party is rumoured to be sailing from tomorrow. In truth, Mücke's deception has worked, as his party prepares to sail on the fourteenth.
- The British and French commanders of Entente forces invading German Kamerun agree to a plan of campaign, in which their forces are expected to reach the line Dume-Lomie-Akoafim-Ntem River by the end of March. The plan, however, bears little resemblance to the actual position of French columns in the south and west, and assumes a level of co-ordination utterly impossible given the terrain of the colony.
