Maximilian von Weichs in Lodz

General der Kavallerie Maximilian Reichsfreiherr von Weichs (Kommandierender General XIII. Armeekorps) gives a military salute to his troops entering the city of Lodz on 9 September 1939, one day after the city in central Poland fell to the Germans. For three days (6-8 September 1939) both sides fought fiercely, and the fall of the city of Lodz opened the way for the invaders to continue their assault on their main goal: the capital Warsaw.
