Frederick the Great's successor, his nephew Frederick William II (1786–97), relaxed conditions in Prussia and had little interest in war. He delegated responsibility to the aged Charles William Ferdinand, Duke of Brunswick, and the army began to degrade in quality. Led by veterans of the Silesian Wars, the Prussian Army was ill-equipped to deal with Revolutionary France. The officers retained the same training, tactics, and weaponry used by Frederick the Great some forty years earlier. In comparison, the revolutionary army of France, especially under Napoleon Bonaparte, was developing new methods of organization, supply, mobility, and command.
