He was temporarily banished to his estate after objecting to his ruler's obsession with (*) Prussian uniforms and training methods.
This man once defended his decision calling for an unordered assault with a wry couplet about "sitting on a rock" and observing an unconquered city.

Legendarily, this man only entered the military after encouragement from the African-born Abram Gannibal. He was temporarily banished to his estate after objecting to his ruler's obsession with (*) Prussian uniforms and training methods. This man's triumphs included a masterful retreat from the Alps with minimal losses when fighting the French and winning the Siege of Izmail against the Turks. He died before he could face off against Napoleon, whom he had been dispatched to counter by his despised ruler, Paul I.  For 10 points, name this Russian general who went undefeated on the battlefield.
