Currently, an interesting experiment in cultural and linguistic revival is underway in Lithuania, exploring the modern Lithuanians connections with the old ethnic Prussians from the same Baltic family.
The first mention of the Old Prussians in historical sources is in connection with Adalbert of Prague who was slain in 997 during a crusade to Christianise the Prussians. By the late 13th century, the German knights, especially the Teutonic Knights had converted them under arms to Christianity. Most of the native Prussians remaining after the bloody conquest were settled to Sambia. The Prussians organized frequent uprisings, the most famous in 1286 and the last in 1525. Before the end of 17th century, the Prussian language had become extinct. The culture of the Old Prussians was Germanicised, or Polonised, depending on the part of Prussia in which they lived. They converted either to Protestantism or to Catholicism (in Warmia).
In this case the barrel of the model 1789 was to shortened to the new regulation 8" (241mm) and using the stock of two broken pistols.
In 1850 the Prussian government decided to convert the pistols to the more reliable percussion ignition, changing the lock and equipping it with a safety-lid.
This pistol was made 1829 in Potsdam, and the conversion happened in 1851.
The Prussian army was commanded by Field-Marshal Helmuth von Moltke and the Prussian General Staff.
The Prussian army was unique in Europe for having the only General Staff in existence, whose sole purpose was to direct operational movement, organise logistics and communications and develop the overall war strategy.
Two Prussian corps attacked the French advanced guard thinking that it was the rearguard of the retreat of the French Army of the Meuse.
