German forces start the invasion of India and the United Kingdom. On the Indian Front, the German Wehrmacht conducts an airborne assault on Kolkata and sends troops south to Cochin to meet other German forces coming down the western coast. Japan intervenes by deploying armored forces with surviving British and Indian units. Another Japabese Navy carrier fleet is also deployed to the Indian Ocean. The Americans lend their support by bombing German convoys. The submarine-carrier flotilla that attacked the Panama Canal, which now exists as a long tunnel to prevent future air attack, is later redeployed to the Bab el-Mandeb to ambush a Kriegsmarine force being sent to the Indian Ocean. Germany, meanwhile, defeats the Soviet Union as Stalin's forces surrender in the Ural Mountains. US forces invade Brittany to ease the pressure off the German invasion of Britain, but the Wehrmacht holds its ground and drives the US forces into the sea, with the last troops forced to leave from their redoubt in Brest. Germany eventually conquers the southern half of England.
