In 1915, despite the demands of the Great Powers directed at the Serbian government to immediately leav Albanian territory since 1913, the Serbs fanatically refused and continued with massacres, atrocities, rape, torture, murder, theft, plunder and other war crimes. These Serbian atrocities against Albanian had occurred constantly since 1912. In 1915, the Serbian command hanged 20 Albanian leaders and decided to set sail on Albanian waters.

From the Meraner Zeitung from 1915:
“The Serbs in Albania. According to a Greek report from Durazzo, 20 Albanian chieftains and many other people were hanged by the Serbs. It is also reported that Serbian vessels are sailing in Albanian waters”
