( Operation Husky ) Italy concludes an armistice with the Allies on September 8th and declares war on Germany on October 13th. This shifts the focus of the S-boats to the eastern Mediterranean in front of the Greek islands occupied by Germany. On the Eastern Front, the German Wehrmacht suffered decisive defeats in the battles of Stalingrad and Kursk , from which it will never recover. The German submarines suffer heavy losses as a result of new reconnaissance techniques, improved weapons, the Allied air superiority and the cracked German Enigma codes . There is also a turning point in the Pacific. The Americans are conquering island by island with the " island hopping " tactic , and their submarines decimate the Japanese transport ships.
