The original painting was titled: Marketenderin zwischen den Regimentern Dessau u. Bayreuth
This is a copy shown in a German magazine which had an article on the paintings in the Jubilee Exhibition of 1886.
The regiments featured in the image are Prussian. The cavalry at the back are the Dragoner-Regiment N0.5 Bayreuth, a dragoon regiment, and the infantry in the front of the image are the 3/6 Kleist Grenadiers of the Anhalt-Dessau Regiment. The figure in the centre is a woman on the pony and was known as a 'Marketenderin" or canteen keeper, so someone who has the regiments water supplies.
The picture shows these two regiments of Frederick the Great's Army at the Battle of Hohenfriedberg , June 4, 1745, during the War of the Austrian Succession. The Bayreuth Dragoons made a real name for themselves at this battle as did the Grenadiers (who were considered an elite fighting force within Frederick's army).
The artist is Fritz Werner, born in Berlin in 1827. He painted this for the Jubilee Exhibition in Berlin in 1886.
It turned out that the client actually had a photograph of an onionskin drawing that he had bought at a book sale in Ithaca, New York. He did not have the original painting. Which was probably just as well, as the painting is currently listed as having being stolen from it's Jewish owner by the Nazi's in WWII, and it has not yet been recovered !
