Example Input: Question: How many divisions did von Reichenau command? Passage:During the Battle of France in 1940, the division came under the command of Erich Hoepner's XVI Panzer Corps, part of von Kleist's Panzer Group in the 6th Army commanded by Walther von Reichenau. After a blitzkrieg assault through Liege and Charleroi, it reached the area of Bethune, where it fought against the British Expeditionary Force in what became known as the battle of Dunkirk. However, due to Adolf Hitler's orders, it did not manage to capture Dunkirk itself. In early June 1940, the division managed to cross a large part of France in several days. By the time that the cease fire was signed, it had reached Grenoble almost unopposed. After several months of occupation duty in France, in late November, the 4th Division was withdrawn to Würzburg, where it was reorganized and reinforced. The 36th Panzer Regiment was detached and assigned to the newly formed 14th Panzer Division, while the 103rd Artillery Regiment was reinforced with a third battalion.
