The Soviet army command ("Stavka") failed to discern the direction of the main German strategic offensive anticipated in 1942, even though they were in possession of the German plans. On 19 June, the chief of operations of the 23rd Panzer Division, Major Joachim Reichel, was shot down over Soviet-held territory while flying an observation aircraft over the front near Kharkov. The Soviets recovered maps from his aircraft detailing the exact German plans for Case Blue. The plans were handed over to "Stavka", in Moscow.
