The Bavarian War Archive supposedly houses the largest collection of World War One aerial photographs in the world. However there is little knowledge of its content. Occasionally the collection is briefly mentioned in publications, mostly emphasising its volume (Fuchs 2000). Fuchs summarises the collection for instance as:
The quantity of the collection is mostly described as “a six number digits of photographs”. Real numbers on the content are not yet available. This collection is known at the Bavarian War Archive as the Bildsammlung-Aufklärung, the pictorial collection of reconnaissance photos. The Bavarian War Archive and also the BS-Aufklärung are archived in accordance with the principle of originality. For the aerial photographs this means that the photographs are arranged according to the units which took the photographs. The majority of the units are of Bavarian origin, although Prussian and occasionally even Württemberg units also show up.
This collection was put together using photographs which had been sent to higher levels such as army groups, armies and divisions or specific users such as cartographic units and artillery commanders. Additionally some series of photographs were ordered by army detachments for a specific tactical use or documentation.
