- In reaction to the Bulgarian entry into the war, the Russian Black Seas Fleet bombards the Bulgarian ports of Varna and Evxinograd, encountering no opposition.
- In two days of heavy fighting the Austro-Hungarian XIX Corps remains pinned on the southern shore of the Save River, and due to heavy losses 205th Landsturm Brigade has been relieved south of Boljevci by 21st Landsturm Mountain Brigade. To the east, the German XXII Reserve Corps and the Austro-Hungarian VIII Corps push out from Belgrade, the former taking the heights at Dedinje and the latter capturing the Vk. Vračar ridge.
Meanwhile General Nikola Zhekov, chief of the Bulgarian General Staff, informs Mackensen today that the offensive of his army, scheduled to begin tomorrow, will be delayed until the 14th. There is also an entirely predictable spat between the German and Austro-Hungarian high commands today. After Mackensen yesterday signalled that German and Austro-Hungarian forces had captured Belgrade, both had issued communiques crediting only their soldiers with the success. Mackensen is quite annoyed at the conflicting stories published by the two high commands, and his operations staff can only explain that both sides had specific victories in the Belgrade fighting that they accomplished on their own - capturing the Konak by the Germans and the Kalemegdan by the Austro-Hungarians.
