Type: Reichskriegsflagge (Sturmflagge)
Period: ca. 19171
Origin: German Empire (Deutsches Kaiserreich)
Dimensions: 95 × 157 cm – this corresponds precisely to an official "Bootsflagge", used on smaller naval vessels such as torpedo boats and gunboats.

Note:1 The estimated production year is based on the assumption that the “Sturm-flg.” marking refers to a unit from the newly formed German storm battalions. These emerged from 1916, with the most likely production and deployment timeframe being 1917.

Description

This is an original war flag used by the Imperial German Navy during the period 1903–1918. It features the characteristic black Iron Cross in the canton, black-white-red tricolor stripes, and the central Prussian eagle. The 3:5 format, fabric weave, stitching method, and wear signs all indicate authentic early 20th-century military production.

Marking (rare variant)

The flag is stamped "Sturm-flg. 95 x 1.57", which is a highly unusual marking not commonly seen on Imperial Navy flags. It likely indicates a special designation, possibly for use by storm troops or naval infantry in combat operations.

Use

Such flags were hoisted on smaller vessels of the Kaiserliche Marine and were also used symbolically or operationally on land—especially during sieges and offensive actions. Naval infantry units occasionally used war flags in the field to represent Imperial authority.

Condition

The flag is in good condition with clearly visible colors, intact design elements, and light wear consistent with use. The markings and stitching indicate high production standards for the period.

Collector Value

This flag represents a rare and valuable artifact from the German Empire’s military history. It is of significant interest to collectors of World War I militaria, Imperial Navy memorabilia, and vexillological artifacts.

Classification

Authentic Imperial war flag, high level of originality.

Appendix: On "Sturmkompanien" in the German Empire

Storm companies (Sturmkompanien) were not part of the original structure of the Imperial German Army before World War I. These specialized assault units emerged only around 1915–1916, developed in response to the stalemated trench warfare on the Western Front.

The first stormtrooper units were developed under Captain Willy Rohr and became known as Sturm-Bataillon Nr. 5 (Rohr). These units rapidly expanded into full storm companies and battalions, employing new tactics based on speed, surprise, and infiltration.

Storm troops were equipped with hand grenades, flamethrowers, carbines, and received extensive close-combat training. They often attacked without long artillery preparation and were tasked with penetrating and disrupting enemy lines.

It is therefore plausible that the "Sturm-flg." marked flag in this profile was issued to or used by such an elite unit—perhaps even a naval infantry company engaged in ground operations. This would explain the unusual marking and adds historical significance to the flag.

Note on Terminology: Could "Sturm" Refer to Weather?

While "Sturm" in German can mean both "storm" (as in weather) and "assault" (as in attack), in military terminology of the German Empire, it almost exclusively refers to combat-related storming actions.

There is no known precedent in Imperial Navy documentation for war flags marked "Sturm" in reference to stormy weather or maritime conditions. Flags used in harsh weather were typically smaller standard flags like the 95×157 cm "Bootsflagge", but these were not specially labeled for weather conditions.

Therefore, while the term could theoretically have been used informally to describe a flag suitable for high winds, it is far more likely that the "Sturm-flg." marking reflects military function—possibly linked to assault troops or special field use.
