The Battle of Freiburg, also called the Three Day Battle, took place on August 3, August 5 and August 9 1644 as part of the Thirty Years' War. The entrenched Bavarians led by Count Mercy retreated after three separate days of being assaulted by the French army under Marshals Conde and Turenne, and the French then went on to capture the city of Freiburg. The Battle of Freiburg produced the highest number of casualties of any battle in the War.
This battle is often confused with the Battle of Freiberg of 1762.
