The Channel Dash (German: Unternehmen Zerberus, Operation Cerberus) was a German naval operation during the Second World War.^[a] A Kriegsmarine (German Navy) squadron comprising two Scharnhorst-class battleships, Scharnhorst and Gneisenau, the heavy cruiser Prinz Eugen and their escorts was evacuated from Brest in Brittany to German ports. Scharnhorst and Gneisenau had arrived in Brest on 22 March 1941 after the success of Operation Berlin in the Atlantic. More raids were planned and the ships were refitted at Brest. The ships were a threat to Allied trans-Atlantic convoys and RAF Bomber Command attacked them from 30 March 1941. Gneisenau was hit on 6 April 1941 and Scharnhorst on 24 July 1941, after dispersal to La Pallice. In late 1941, Adolf Hitler ordered the Oberkommando der Marine (OKM; German Navy High Command) to plan an operation to return the ships to German bases in case of a British invasion of Norway. The short route up the English Channel was preferred to a detour around the British Isles for surprise and air cover by the Luftwaffe and on 12 January 1942, Hitler gave orders for the operation.^[1]

The British exploited decrypts of German radio messages coded with the Enigma machine, air reconnaissance by the RAF Photographic Reconnaissance Unit (PRU) and agents in France to watch the ships and report the damage caused by the bombing. Operation Fuller, a joint Royal Navy–RAF contingency plan, was devised to counter a sortie by the German ships against Atlantic convoys, a return to German ports by circumnavigating the British Isles, or a dash up the English Channel. The Royal Navy had to keep ships at Scapa Flow in Scotland in case of a sortie by the German battleship Tirpitz from Norway. The RAF had sent squadrons from Bomber and Coastal commands overseas and kept torpedo bombers in Scotland ready for Tirpitz, which limited the number of aircraft available against a dash up the Channel, as did the winter weather which reduced visibility and blocked airfields with snow.

On 11 February 1942, the ships left Brest at 10:45 p.m. (German time) and escaped detection for more than twelve hours, approaching the Strait of Dover without discovery. The Luftwaffe provided air cover in Unternehmen Donnerkeil (Operation Thunderbolt) and as the ships neared Dover, the British belatedly responded. Attacks by the RAF, Fleet Air Arm, Navy and bombardments by coastal artillery were costly failures but Scharnhorst and Gneisenau were damaged by mines in the North Sea (Scharnhorst was out of action for a year). By 13 February, the ships had reached German ports; Winston Churchill ordered an inquiry into the debacle and The Times denounced the British fiasco. The Kriegsmarine judged the operation a tactical success and a strategic failure because the threat to Atlantic convoys had been sacrificed for a hypothetical threat to Norway. On 23 February, Prinz Eugen was torpedoed off Norway and after being repaired, spent the rest of the war in the Baltic. Gneisenau went into dry dock and was bombed on the night of 26/27 February, never to sail again; Scharnhorst was sunk at the Battle of the North Cape on 26 December 1943.
