On July 28, 1914, a war began that would later be called the Great War, the First World War, or even the War to End All Wars. It lasted more than 4 years and ended on November 11, 1918. Its beginning marked the entry of humanity into a new era, in which combat operations became part of everyday life - they no longer took place “out there”; they were carried out in cities and towns, in villages and hamlets, on land and at sea, underground and in the air - in a word, everywhere.
