In defiance of the 1907 Hague Convention on Land Warfare, the German occupiers engaged in mass atrocities against the civilian population of Belgium and looting and destruction of civilian property, in order to flush out the Belgian guerrilla fighters, or francs-tireurs, in the first two months of the war, after the German invasion of Belgium in August 1914.
As Belgium was officially neutral after hostilities in Europe broke out and Germany invaded the country without explicit warning, this act was also in breach of the treaty of 1839 and the 1907 Hague Convention on Opening of Hostilities.
