English: PoW camp Heinrichsgrün. Between 1915 and 1918 Jindřichovice (German: Heinrichsgrün, Bohemia) was the location of one of the largest prisoner-of-war camps in the territory of the Austro-Hungarian Empire during World War I, where about 40,000 prisoners-of-war passed. The camp held Italians, Russians, but mostly Serbs – both soldiers and civilians – captured by the Austro-Hungarian army during the Serbia campaign and transported by rail to the camp. Conditions in the camp killed up to 40 people per day. Every day at 3 PM a sad procession of the dead went to a nearby common grave, where the remains of the victims of all ages were reposed.
