The beginning of 1941 is marked with British and Australian Forces attacking the Italians in North and East Africa. The Italians turn out to be no match for the Commonwealth troops and are forced to retreat. Over 25000 Italians are taken prisoner. The huge defeat of the Italians makes Adolf Hitler decide to send the Afrika Korps under command of Erwin Rommel to North Africa. Rommel quickly organises his troops and starts attacking the Commonwealth troops, regaining territory on them. In June, the Commonwealth troops in the desert unsuccessfully try to counterattack the German offensive.
In the Balkan Germany also comes the Italians to aid. In April they invade Yugoslavia and Greece. Yugoslavia is forced to surrender within two weeks. And even though Greece is supported by over 60000 Commonwealth troops their army must do the same only a few days later. The remainder of the Greek army and most Commonwealth troops evacuate to Crete. By the end of May the Germans launch an airborne assault against Crete. Ten days later the island is under full control of the Germans. Half of the Commonwealth troops are able to evacuate, the remainder is forced to surrender or join the partisan groups on the island.
In the North Atlantic Ocean German U boats and raiders sink massive amounts of tonnages. By the end of May the German battleship Bismarck is sent to destroy more convoys. The British try to stop the ship but loose the battleship HMS hood in their first contact a few days the Bismarck is hit by a torpedo from an aircraft of the aircraft carrier HMS Ark Royal. With her rudder disabled by this hit, the Bismarck becomes an easy prey for British fleet. The next days the Bismarck is sunk.

The Germans use the blitzkrieg tactic again and gain ground fast. Bulgaria, Slovakia, and Albania join them. Finland attacks the Soviet Union from the North to regain the land lost during the earlier confrontation between the two countries. Turkey does not join them but signs a friendship treaty with Germany. The Soviet Union tries to counterattack every now and then but they out te be no match for the Axis. With winter coming the German advance comes to a halt.
