In 1942, the tide began to turn against the Axis powers in several key battles. The Russians launched a counteroffensive against the Germans at Moscow in December 1941 after the Germans were not equipped for the harsh Russian winter. Also in 1942, the Wannsee Conference was held near Berlin to coordinate the deportation of Jews to extermination camps in occupied Poland. At the same time, the Japanese rapidly advanced against British and American forces in the Pacific, capturing several territories. However, they were stopped at the Battle of Midway in June 1942 when the US sank four Japanese aircraft carriers, changing the course of the war in the Pacific.
