- Day 820 of the war
- Cornelius Joseph Murphy enlists. Cornelius is commemorated on the Centenary of WWI in Orange Honour Roll; he would be killed in action at Bullecourt, France, on 4 May 1917.
- French troops under the command of General Robert Nivelle, launch a new offensive at Verdun, targeting Fort Douaumont and other German-occupied sites on the east bank of the Meuse River. Under a cover of fog, French forces attack the German-occupied fort from nearby Souville Hill, employing an effective new tactic in which they slowly advance in stages, step-by-step behind encroaching waves of artillery fire. Using this creeping barrage tactic, they seize Fort Douaumont, capturing some 6,000 prisoners by the end of the day. Nine days later they succeed in retaking Fort Vaux. Fighting continues until 18 December.
- The German-Bulgarian Army under the command of General August von Mackensen advance north and north-west of Constanza in the Dobrudja province of Romania. The army reaches Mejidia, on the railway line linking the Danube and the Black Sea, and captures 6,700 prisoners.
- Serbian troops take heights on the left bank of the Cherna River on the Southern Front
