In the spring of 1915, Austro-Hungary and Germany strived to break through the front, which remained in the same place for several months, and to drive the Russian forces out of Galicia and the territory of the Congress Kingdom of Poland. The main attack was to be carried out by the 11th German Army commanded by General August von Mackensen together with the Third and Fourth Austrian Army commanded by Archduke Joseph Ferdinand. In the morning of May 2, 1915, the Austro-Hungarian and German Infantry launched a mass attack on the Russian positions in the region of Łużna and Gorlice. Pustki Hill was one of the strategically most significant places. After a few-day-long firing at the hill, bloody battles were fought on May 2, 1915, to capture it, and finally, the imperial banner was planted on the hill’s top. The Austrians and Germans successfully continued the offensive in the subsequent days, eventually achieving a great success.
