I'm writing an IA (basically a long historical investigation) for my Ib History class and I'm discussing the impact the Soviet leaders had on the victory at Stalingrad. However, I'm having a really hard time finding a substantial (~20-30 pages academic journal) on Marshal Vasilii Chuikov and his role at Stalingrad. Does anyone know of some sources I could possibly find/use? Even a point in a right direction would be extremely helpful.
