大英百科全書話希特拉本身的確係諗住打油田,順道攻斯大林格勒,但打到咁上下突然改命令,主力變左要攻陷斯大林格勒喎...
一開始係要油田先:Hitler’s goal was to eliminate Soviet forces in the south, secure the region’s economic resources, and then wheel his armies either north to Moscow or south to conquer the remainder of the Caucasus.
然後改口話要兵分兩路又要油田又要斯大林格勒:On July 9 Hitler altered his original plan and ordered the simultaneous capture of both Stalingrad and the Caucasus. Army Group South was split into Army Group A (under Field Marshal Wilhelm List) and Army Group B (under Bock).
之後直頭抽走油田軍力北上主攻斯大林格勒:For his part, Hitler continued to directly intervene at the operational level, and in August he ordered Hoth to turn around and head toward Stalingrad from the south.
