Book excerpt: This volume of WWII military studies examines significant yet neglected clashes of German-Hungarian and Soviet armor north of the river Danube. In Days of Battle, Dr. Norbert Számvéber, chief of Hungary's military archives, examines armor combat operations in the southern territory of the historical Upper Hungary (part of Hungary between 1938 and 1945, at the present time now part of Slovakia) in three separate studies. The first is an account of the battle between the Ipoly and Garam rivers during the second half of December 1944, in which the élite Hungarian Division "Szent László" saw action for the first time. The second study examines the fierce tank battle of Komárom, fought between January 6th–22nd of 1945. This was an integral part of the Battle for Budapest, parallel in time with Operation Konrad. The third study describes the combat during the German Operation Südwind in February 1945, as well as the Soviet attack launched in the direction of Bratislava in March 1945. Based on files and documentation from German, Hungarian and Soviet sources, Dr. Számvéber’s authoritative text is supported by photographs and color battle maps.
