Appendix C
Bibliographical Note
The German sources used in preparing this study included those Fuehrer directives, fragmentary diaries, and records of the Armed Forces High Command that pertained to planning and operations in Russia; the official records of the Organization, Intelligence, Operations, and Logistical Divisions of the Army High Command: selected war diaries of the army group and army headquarters that participated in the Russian campaign; and the Halder War Diaries.
In describing the preparation and execution of the German summer offensive of 1942, the author made extensive use of the Kaukasus (Caucasus) files of the Planning Branch, Operations Division, Army High Command. He also consulted the records of the Technische Brigade Mineraloel Russland (Technical Brigade, Mineral Oil, Russia) which was directed by the Armed Forces Economics Office.
Another source of information was the "Strategic Survey of the German Campaign in the East," a postwar study prepared by a group of German general officers under the supervision of General Halder.* The memoirs and postwar writings of such, outstanding German military leaders and historians as Greiner, Guderian, Heinrici, Heusinger, Kesselring, Rundstedt, Tippelskirch, and Warlimont were also used. In addition, the author conducted a series of personal inter views with former German Army and Luftwaffe officers in order to fill a number of gaps in the sources.
