The Battle of Hürtgen Forest (2020)

In the autumn of 1944, US forces advanced into the Hurtgen Forest, which was the last obstacle to crossing the Rhine River and into the heart of Germany. It turned out to be one of the bloodiest battles of the war, lasting until the winter of 1945. It was estimated that more than 30,000 US and German soldiers were killed, and tens of thousands more wounded, before the battle was over. The fighting was so fierce and bloody that the area became known to those who fought in it as "The Death Factory".
