In 1870, von Werner spent the final phase of the Franco-Prussian War at the headquarters of the Third Army led by Prussian crown prince Frederick William.
The crown prince had impressed the design of the Palace of Versailles, which presented itself to visitors as a national site of fame in France, furnished with historical paintings.
He wanted something similar for Berlin, but, unlike Napoleon Bonaparte, he had not come to the idea that the imminent ceremony would be designed by the painter for posterity.
Napoleon had allowed Jacques-Louis David to stage the furnishing and the appearance of the actors in his imperial crown for a historical painting.
Thereupon, the Grand Duke of Baden issued a "Hoch" ("Hurrah") to "His Majesty Emperor William", which those who were in attendance repeated three times.
During the work, an almost friendly relationship with the Crown Prince came about, as well as the personal relations to Federal Chancellor Bismarck and Emperor William.
The adjoining oil painting by Victor Bachereau-Reverchon (1842-1885) shows the comparatively narrow space, from whose end the flat gallery for the Emperor had already been removed.
Werner determined the image format according to a place he had chosen in the "White Hall", the largest of the château, which was used for public events such as the opening of the Reichstag and the grand court.
His visit was the end and highlight of the guided tours through the representative rooms of the castle, where several hundred paying visitors took part every day.
The great popularity of the painting prompted William I to entrust Werner with the production of the imperial proclamation in the newly erected Hall of Fame of the Prussian Army in Berlin's Zeughaus.
There, opposite to the entrance of the Ruler's Hall, two wall paintings of Werner's flanked the figure of the victorious goddess Viktoria von Fritz Schaper.
At the lowest level, Bismarck, whom Werner had emphasised for colour composition with white uniforms, turned to him, Roon, Moltke and other German commanders.
Werner even further reduced the group of officers, placing Georg von Kameke, who had now been appointed Minister of War, in the foreground while others came to the rear.
The Prussian Army, with Bavaria, were now documented by a hand of the Prussian General Leonhard von Blumenthal with his Bavarian comrade Jakob von Hartmann, emphasised by his high head of hair and light blue uniform.In the reception of the second painting, it was often problematic that some features such as the now white uniform of Bismarck and his decoration of the Pour le Mérite do not correspond to the actual historical situation of 1871.
Only a strict Cuirassier on the left in the foreground, represents the simple soldiers, namely Louis Stellmacher of Lychen of the Gardes du Corps regiment (see picture).
The wall painting survived the air raids on the Zeughaus in November 1943, but was no longer in its frame after further damage to the building at the end of the war.
