The collapse of the German army in the East in the summer of 1944

is a two volume publication, by Stephen Ariel Veal Portland State University. "The collapse of the German Army in the East in the Summer of 1944 is analyzed and determined to be the result of the following specific factors: German intelligence failures; German defensive doctrine; loss of German air superiority; Lend-Lease aid to the Soviet Union; German mobile reserves committed in the West; Soviet numerical superiority; and Soviet offensive doctrine and tactics. The collapse of Army Group Center, the destruction of the XIII Army Corps, and the collapse of Army Group South Ukraine in Romania during the Summer of 1944 are examined in detail. The significance of the collapse of the German Army in the East is compared to events occurring on the Anglo-American fronts and the German losses on both theaters of military operations are compared. The Soviet contributions to the defeat of the German Army during the Summer of 1944 are examined and the views of Soviet historiography and American historiography compared."
