Ingame description
In 1857 Helmuth von Moltke was appointed Chief of the Prussian General Staff, which he soon set about reforming. Among the ideas implemented by von Moltke were a department for historical studies, extensive wargaming exercises and a special department dedicated to cataloging and studying the telegraph and railway networks of Prussia, and how they could be used to best effect in the event of war. The end result was that, by the time of the Franco-Prussian war, Prussia's General Staff was considered the most efficient in Europe, it's methods soon becoming widely studied and adopted abroad. Moltke remained Chief of the Prussian Staff for the next 30 years, and is known as one of the most brilliant military strategists of the 19th century.
