Beginning with the 1941-1942 Russian winter offensive, this volume of the history of the war by Strategicus carries the story up to the gates of Stalingrad and to the last defences of Egypt. As in previous volumes, this book contains chapters on the strategical and tactical bearing of developments on the sea and in the air. "The period covered by the present volume saw major operations for the first time extend to the five continents. When Japan entered the war the German campaign had already died down and although Russia waged a persistent offensive against German positions during the winter it was a matter of what might be called 'task forces'. The mobility of a force during winter, in that period, varied inversely with its weight. Later on, however, Germany resumed her attempt to secure a decision in Russia while the Japanese offensive was still in full swing in the Far East. In May there even seemed to develop a terrible climax. Hitler, in that month, in the Crimea, began his summer offensive, while in North Africa he was again trying to defeat the Eighth Army, and Japan was reducing Corregidor, overrunning the Chinese airfields within raiding distance of Tokyo and fighting the battle of the Coral Sea. Madagascar was invaded by Britain and Russia attacked over a broad front towards the great centre of Kharkov."
