On 25 July 1944, the 2nd Parachute Division was involved in the defense of Brest against the American 7th Corps. American forces suffered 4,000 casualties in its effort to invest the port. Other elements of the 2nd Parachute Division were destroyed by American armored forces while on their way to assist the 5th Parachute Division at St. Malo. American forces captured Brest on 20 September 1944. What was left of the 2nd Parachute Corps was sent to Cologne after Falaise for rest and refitting. Heydte's 6th Parachute Regiment went to Guestrow-Mecklenburg to form the foundation of a new regiment.
