David Glantz indicated that four hard-fought battles – collectively known as the Kotluban Operations – north of Stalingrad, where the Soviets made their greatest stand, decided Germany's fate before the Nazis ever set foot in the city itself, and were a turning point in the war. Beginning in late August, continuing in September and into October, the Soviets committed between two and four armies in hastily coordinated and poorly controlled attacks against the Germans' northern flank. The actions resulted in more than 200,000 Soviet Army casualties but did slow the German assault.
