Panzerschlachten ("Panzer Battles") is the German language title of Major-General Friedrich W. von Mellenthin's autobiographical account of his service in the Panzer arm of the Wehrmacht Heer during World War II. The most prominent English language version is Panzer Battles: A Study of the Employment of Armor in the Second World War, © 1956 University of Oklahoma Press, translated by H. Betzler and edited by L. C. F. Turner.
The book gives very good details of the fluid nature of armoured warfare during the Second World War. It largely covers North African battles while also covering some engagements on the Eastern Front.
