1st ed., 1969. Xiii + 635 pp., photo-plates. D.j., 24 x 16cm. V.G.+. On June 22nd, 1941, the German armies crossed the Russian frontiers. Within six weeks Army Group North were within 30 miles of Leningrad, an advance of over 400 miles. A month later the Germans had all but completed the city’s encirclement; only a perilous route across Lake Ladoga connected Leningrad with the rest of Russia. The Germans got no further. 900 days later their retreat began. It is of this epic siege, the longest endured by any city since biblical times, and of the fantastic blitzkrieg that preceded it that the author now tells in one of the great books about World War II.
