I want to know the answer to the following question:
In what year did the Battle of Auerstadt take place?
All the background I'm provided with is that "At the Battle of Auerstadt in 1806, King Frederick William III of Prussia outnumbered the French by 63,000 to 27,000; however, when he mistakenly was told that Napoleon was in command, he ordered a hasty retreat that turned into a rout.". Is that enough to answer the question?
