James Francis Edward Keith
Field Marshal (Prussian service)
"The great art of war is to change plans as often as the enemy changes his."
Biography
A Scottish Jacobite who fought at Sheriffmuir (1715) and fled Scotland after the rising failed, Keith served Russia before entering Frederick the Great's service in 1747. By then a seasoned professional, Keith quickly became Frederick's most dependable commander — the general Frederick trusted to execute complex operations independently. He died at the Battle of Hochkirch in 1758, during the Seven Years' War, which Frederick considered a personal loss as much as a military one. Frederick built him a statue in Berlin that still stands.
