An expert on German military history offers the first extensive, English-language study of one of the critical campaigns of World War I. The Eastern Front in World War I has been neglected for too long. Breakthrough: The Gorlice-Tarnow Campaign, 1915 is the first English-language study of the first of the great breakthrough battles of the war-one of the Great War's critical campaigns. The book covers the initial attack of the German Eleventh Army and the Austro-Hungarian Third and Fourth Armies in Galicia as they outflanked the Russian position in the Carpathian Mountains that threatened Hungary. Subsequent chapters cover the retaking of Galicia, including the recapture of Przemysl and Lemberg. The examination concludes with the German and Austro-Hungarian forces under the command of August von Mackensen turning north from Lemberg and the subsequent overrunning of Russian Poland by the Central Powers.
