Catherine the Great will say of him "" If Münnich is not one of the children of Russia, he is one of the fathers "". Frederick the Great professes great admiration for his exploits and calls him "Prince Eugene of the Muscovites". Voltaire wrote for his part: " It was Prince Eugene of the Muscovites; he had the virtues and vices of the great generals: skilful, enterprising, happy; but proud, superb, ambitious, and sometimes too despotic, and sacrificing the lives of his soldiers for his reputation. Franz Lacy, Keith, Löwendal, and other skilful generals, were training in his school ".
