Attack on Durres 1918
On the Thessaloniki front, on 15 September 1918, the agreed Oriental Army launched an attack on the defensive line defended mainly by the Bulgarian army supplemented by German troops. Its right flank (in Albania) was protected by the Austro-Hungarian Army. This line was breached in just one week and after another week the Bulgarian army capitulated. This created a huge gap in the front which there was nothing to fill. The Austrian troops in Albania were threatened with encirclement and it was therefore decided to vacate Albania on 28 September.
