Polish Southern Front

Since German units had established several bridgeheads along eastern bank of the San river, Sosnkowski decided to break through enemy lines in order to reach Lwow.

The general had no idea that on September 12, the Germans had destroyed 24th Infantry Division near Bircza, and 3rd Mountain Brigade near Sambor.

On September 14 Przemysl fell to the Wehrmacht, and Sosnkowski's forces retreated to Sadowa Wisznia, where they concentrated and marched to Lwow.

On September 15 and 16, Poles managed to repel German attacks in the forests of Jaworow, destroying among others, SS Germania Regiment.

On September 17, Sosnkowski was ordered to march to the Romanian Bridgehead, but was unable to achieve this, due to German encirclement of his army.
