author
A Prussian military history section rather than a single individual, this institutional author produced detailed official studies of 19th-century and early 20th-century wars. Its works are valued for their documentary approach and for showing how the German General Staff analyzed campaigns, strategy, and lessons from combat.

by Prussia (Germany). Armee. Grosser Generalstab. Kriegsgeschichtliche Abteilung II
This name refers to the Kriegsgeschichtliche Abteilung II of the Großer Generalstab—the Historical Section II of the Prussian, later German, Great General Staff. In library records and older book imprints, the section often appears as the corporate author of official military histories, campaign studies, and translated staff publications rather than as a personal author.
The section is especially associated with painstaking studies of major conflicts, including works on the Franco-Prussian War and other campaigns that were meant to preserve records, analyze operations, and support professional military education. Because these books were produced by an office inside the General Staff, they tend to read with the authority and structure of official history: methodical, document-heavy, and closely focused on planning, movement, and command.
For modern readers, these volumes offer more than battlefield narrative. They also open a window onto how the Prussian and German military establishment understood war, organized knowledge, and turned past campaigns into lessons for future officers.
