According to some sources, the Blutfahne (blood banner or flag), was the battle flag originally used by the Holy Roman Emperor. Later, when a German vassal was given a fief in the 13th Century by the Emperor, with the "jurisdiction of the blood," (the power to take life), the blood banner was used as a sign of that power and sometimes the red flag was used by the vassal as his battle banner. Some landsknechts in the late Middle Ages also used the Blutfahne as the battle flag.

The colours red and white were very significant in the Holy Roman Empire. When the Holy Roman Empire took part in the Crusades, a red and white war flag was flown alongside the black-gold Imperial banner.

An additional military flag associated with the Empire worth mentioning is the Sankt Georg Fahne - a white St. George's cross on a red field, frequently with a schwenkel, or red tail. It basically was the Military Flag of the Holy Roman Empire (above), square instead of retangle shaped, with the tail added.

Like the Imperial Banner, the War flag, also known as the Reichsturmfahne, or Imperial Assault Banner, had a black (one-headed) eagle on a gold field, with a red schwenkel (tail) attached.

During the Holy Roman Empire, counties (Graftschaft) were ruled by Counts. Fürstenberg was one such county in Swabia, present-day southern Baden-Württemberg, Germany. It was originally called the county of Freiburg, but Count Henry I, the Count of Fürstenberg (1250–1284), renamed it after his residence at Fürstenberg Castle at the beginning of his reign.

Accroding to source this regiment was divided into at least 10 companies. The image of the 6th company is given, the flags of the companies 7, 8, 9 and 10 are described. [neu39a] mentions, that this type is very seldom. The companies of this regiment all have the same pattern, but the colours are varied. So having the same pattern, the flags can be reconstructed.

Flags used at the Battle of Moncontour 1569 during the Third Huguenot War (1568-1570) were quite distingue. The war fought between the Catholics and the Protestants (Huguenots) broke out half a year after the end of the 2nd Huguenot war. The Protestants were defeated in March of 1569 at Jarmac and their leader Louis I of Bourbon-Condé was captured and executed, Admiral Coligny, the new leader of the Protestants, was defeated at Moncontour in October of 1569. The winner was the future King of France, Henry III.

This is an example of a Ducal cavalry flag used at the Battle of Moncontour in October of 1569 during the Third Huguenot War in France.

The Regiment Hohengeroldseck was lead by Count Quirin Gangolf of Hohengeroldseck, which was a small territory in the Black Forrest. The Count was colonel of 15 companies and in service of Wolfgang of Palatinate-Zweibrücken. The flags of all companies were red and yellow with the white cross. The patterns of the companies were different. The hoist was yellow, flamed five times horizontally red. The fly was red with the white cross of the Alliance of Huguenots atn its center.

The Regiment Granweiler was another German regiment at the Battle of Moncontour in October of 1569 during the Third Huguenot War in France. This regimental flag had a 7-stripes, divided horizontally. The central stripe was red with the white cross of the Alliance of Huguenots in its center. The others stripes were from top to bottom: red-yellow-mixed colors-mixed colors-blue-white. The mixed color stripes were divided horizontally twice into blue-red-yellow-white(upper) and white-yellow-red-blue(lower).
