Reading a WW1 article recently, I found a mention about a battle that took place on 2nd of October 1916 on the outsides of Fogaras: "if on October 2nd the allied troops (German and Austro-Hungarian) were dismissed in front of Fogaras, the next day the city was evacuated by the Romanians and surrendered, the Romanian troops retreating to Brasov on fortified positions at the foot of the Perșani Mountains". On the local museum, there's a nice photo dated 3rd of October same year, with the Austro-Hungarian and German soldiers marching on the town square. Unfortunately, I haven't found any other refference to this battle. Can I get some help please? This picture is possible to be a few days after the battle

I finally got an answer by reading "Austria-Hungary's last war 1914-1918", pages 295 to 305. I also explained explained it on a video. Check this link if you are curious to find more:
