Western Allied invasion of Germany and Operation Undertone, occurred during which event?
Operation Undertone Operation Undertone was a large assault by the U.S. Seventh and French 1st Armies of the U.S. Sixth Army Group as part of the Allied invasion of Germany in March 1945 during World War II.
Channel Dash The Channel Dash or Unternehmen Zerberus (Operation Cerberus) was a German naval operation during World War II. A "Kriegsmarine" (German navy) squadron of both of the "Scharnhorst"-class battleship s, the heavy cruiser "Prinz Eugen" and escorts, ran a British blockade from Brest in Brittany, where they had been a fleet in being and a latent threat to British trans-Atlantic convoys. At Brest and La Pallice, the ships had been attacked by Royal Air Force (RAF) Bomber Command and by RAF Coastal Command torpedo-bombers from March 1941, which inflicted periodic damage to the ships, reducing their seaworthiness. In late 1941, Adolf Hitler ordered "Oberkommando der Marine" ("OKM" Navy high-command), to plan an operation to return the ships to German bases, to counter a possible British invasion of Norway. The short route up the English Channel was preferred to a detour around the British Isles, to benefit from surprise and from air cover by the "Luftwaffe".
