It was a tank battle exceeded in size and significance only by the famous defeat of Germany's Panzer force near Kursk in 1943. And yet, little is known about this weeklong clash of more than two thousand Soviet and German tanks in a stretch of northwestern Ukraine that came to be known as the "bloody triangle." This book offers the first in-depth account of this critical battle, which began on 24 June 1941, just two days into Operation Barbarossa, Hitler's invasion of the Soviet Union. Author Victor Kamenir describes the forces arrayed against each other across that eighteen-hundred-square-mile-triangle in northwestern Ukraine. Providing detailed orders of battle for both Wehrmacht and Red Army Forces and contrasting the strengths and weaknesses of the Soviet and German tanks, he shows how the Germans slowly and decisively overwhelmed the Russians, apparently opening the way to Moscow and the ultimate defeat of the Soviet Union. And yet, as Kamenir's account makes clear, even at this early stage of the Russo-German war the Soviets were able to slow down and even halt the Nazi juggernaut. Finally, the handful of days gained by the Red Army did prove to have been decisive when the Wehrmacht attack stalled at the gates of Moscow in the dead of winter, foreshadowing the end for the Germans.
