The Channel Dash, codenamed Operation Cerberus by the Germans, was a major naval engagement during World War II in which a German ''Kriegsmarine'' squadron consisting of both s, and the heavy cruiser along with escorts, ran a British blockade and successfully sailed from Brest in Brittany to their home bases in Germany via the English Channel. The move was ordered for two reasons: on the one hand Brest was within reach of British planes and became too dangerous, on the other hand, from a base further north, it would be easier to interdict North Atlantic convoys, which were giving the Soviet Union much needed and growing help. On 11 February 1942, the ''Kriegsmarine''s ships left Brest at 21:14 and escaped detection for more than 12 hours, approaching the Straits of Dover without discovery. As the German ships passed through the straits and on into the North Sea, British armed forces intercepted them, and the Royal Air Force, the Fleet Air Arm and Coastal Artillery attacked. The attacks and bombardment were unsuccessful, and by 13 February all the ''Kriegsmarine''s ships had completed their transit. In support of the German naval operation, the ''Luftwaffe'' launched Operation Donnerkeil (Thunderbolt) to provide air superiority for the passage of the ships. ==German plan== and had arrived at Brest on 22 March 1941 after operations against Allied shipping in the Atlantic Ocean. ''Prinz Eugen'' appeared at dawn on 1 June at Brest Harbour after participating in Operation Rheinübung (Exercise Rhine). Here the ships were able to repair and refuel but were also subject to frequent air attacks. In light of this, Adolf Hitler ordered the ''Kriegsmarine'' to move the ships to their home bases. The Berlin Admiralty preferred the Denmark Strait passage but also considered the shorter but more dangerous route through the English Channel. The matter was quickly resolved by Hitler in favour of the Channel, and all planning for the fleet transfer was passed on to the German Naval Command West in Paris. Although the operation would be under Vice Admiral Otto Ciliax, who commanded the Brest Group (flying his flag on ''Scharnhorst''), Naval Command West under Admiral Alfred Saalwächter was responsible for all planning and operational directions. As the operation had been ordered personally by Hitler, mine sweepers were deployed, additional radar jamming stations were set up, U-boats were sent for meteorological observations and several destroyers steamed westward down the Channel to Brest to strengthen the escort screen. Fighter ace general Adolf Galland attended planning sessions on ''Scharnhorst'' and promised day and night fighter cover along the route. During January, German navy and air force made several large scale practice runs, to ensure seamless cooperation between navy and air force. Admiral Ciliax, who was personally pessimistic about the success of Operation Cerberus, had his own problems. His great ships were no longer the fine fighting machines they had been, nor did they look like it. While at Brest, many technicians and experts were detailed away for urgent requirements elsewhere. But morale on the ships was good; there had been no sabotage at Brest and the crews went ashore freely. Among the sullen locals there was no doubt that the ships were preparing to depart. To make the French believe (and pass on to the British) that they were heading for the South Atlantic, rumours were spread in town, tropical helmets were brought on board and French dock workers loaded oil barrels marked "For Use in the Tropics." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Channel Dash」の詳細全文を読む スポンサード リンク
