For all the advances made against the Germans in the west between D-Day on 6 June 1944 and the crossing of the Rhine in March 1945, postponed by the disaster at Arnhem in mid-September and the Ardennes counter-offensive in the winter, it was on the Eastern Front that the war against Germany was won. Between Operation Barbarossa and December 1944, the Germans lost 2.4 million men killed there, against 202,000 fighting the Western allies. The cost of inflicting such casualties was uneven: between D-Day and VE Day (Victory in Europe Day, 8 May 1945), the Russians suffered more than 2 million casualties, three times that of the British, Americans, Canadians and French fighting forces put together. It is worth considering whether democracies could ever have tolerated that level of sacrifice, or whether – as seems likely – it required the whole horrific apparatus of the NKVD and domestic terror to keep the Soviet Union in the war.
After the Wehrmacht’s convincing defeat at Stalingrad and the capture of Field Marshal Paulus’ Sixth Army in February 1943, and then the withdrawal with unacceptable losses – albeit fewer than the Russians suffered – at the battle of Kursk six months later the scene was set for a series of enormous Soviet offensives across the eastern part of the Eurasian land mass that were only to end with Germany’s surrender in Berlin in early May 1945, after Hitler’s suicide there on 30 April. In its 1943 summer offensive after the successful defence of Kursk, the Red Army recaptured Orel, Kharkov, Tagonrog and Smolensk, forcing the Germans back to the Dnieper river and cutting off the Seventeenth Army in the Crimean peninsula. Hitler came under pressure from Field Marshal Erich von Manstein and the Romanian dictator Marshal Ion Antonescu to evacuate the German and Romanian forces from the Crimea, which could have been used in the defence of Romania and Bulgaria, but his obstinate refusal to do so meant the fall of both countries in short order, and the eventual destruction of the army group there. Hitler had a scheme for the Crimea to become a solely Aryan colony from which all foreigners would be permanently banned, and he hung on to his dream for it long after military considerations dictated that they needed to be – at the very least – postponed.
