Two years into the war, in September 1941, German arms seemed to be carrying all before them. Western Europe had been decisively conquered, and there were few signs of any serious resistance to German rule. The failure of the Italians to establish Mussolini's much-vaunted new Roman empire in the Mediterranean had been made good by German intervention. German forces had overrun Greece, and subjugated Yugoslavia. In north Africa, Rommel's brilliant generalship was pushing the British and allied forces eastwards towards Egypt and threatening the Suez canal. Above all, the invasion of the Soviet Union in June 1941 had reaped stunning rewards, with Leningrad (the present-day St Petersburg) besieged by German and Finnish troops, Smolensk and Kiev taken, and millions of Red Army troops killed or captured in a series of vast encircling operations that brought the German armed forces within reach of Moscow. Surrounded by a girdle of allies, from Vichy France and Finland to Romania and Hungary, and with the more or less benevolent neutrality of countries such as Sweden and Switzerland posing no serious threat, the Greater German Reich seemed to be unstoppable in its drive for supremacy in Europe.
Yet in retrospect this proved to be the high point of German success. The fundamental problem facing Hitler was that Germany simply did not have the resources to fight on so many different fronts at the same time. Leading economic managers such as Fritz Todt had already begun to realise this. When Todt was killed in a plane clash on 8 February 1942, his place as armaments minister was taken by Hitler's personal architect, the young Albert Speer. Imbued with an unquestioning faith in Hitler and his will to win, Speer restructured and rationalised the arms production system, building on reforms already begun by Todt. His methods helped increase dramatically the number of planes and tanks manufactured in German plants, and boosted the supply of ammunition to the troops.
