1. Napoleon Bonaparte

Born
 a Corsican, Napoleon became by far the most able general of the modern 
age, rising from obscurity during the Revolution to Consul and Emperor 
of the French Empire which spanned from Madrid to Moscow and from Oslo 
to Cairo. Originally an artilleryman, he led campaigns that conquered 
the Italian States, Austria, Egypt, Prussia, Spain, the Netherlands, 
Swedish Pomerania, parts of the Caribbean, and large swathes of Russia. 
Leading brilliant campaigns, using concentrated force in lightning 
strikes on the field, developing independent and complete army corps (a 
system still modeled today), installing puppet rulers, conscripting 
troops from each nation he subdued, and inspiring a host of marshals who
 were all able tacticians themselves (Murat, Massena, Bernadotte, Ney, 
and many others), Napoleon revolutionized warfare. No less than four 
international alliances of powers were required to bring his empire to 
its knees, and without the simultaneous pressure or Russian winter, 
British naval domination, Spanish guerillas, and Wellington’s stolid and
 unbreakable Anglo-Spanish-Portuguese Army, very likely Bonaparte would 
have sat astride the his European conquests for years to come.
2. Hannibal Barca

The
 most feared opponent Rome ever faced, this Carthaginian general was 
raised to the task of defeating the Romans from early childhood by his 
father, Hasdrubal. Hannibal abandoned previous Carthaginian tactics of 
passive naval superiority, and marched a force on elephants over the 
Italian Alps. Defeating the Romans at nearly every battle he fought, he 
made a Roman general, Quintus Fabius Maximus, famous merely for being 
able to delay Hannibal’s advance without enormous loss of life (Fabius 
was granted the title “Cunctator”, or delayer, by the Roman senate). At 
Cannae, Hannibal’s forces, cobbled together and suffering from losses, 
routed an enormous Roman army, killing or capturing upwards of fifty 
thousand enemies. Eventually defeated by Scipio Africanus and deserted 
by his government, he remained a scourge the Romans invoked to justify 
razing Carthage.
3. Salah ad Din

Saladin,
 as he is known in our language, was the most outstanding leader of the 
Crusades, hampering the fledgling crusader states and European invasions
 with equal aplomb. Known for his calm and rationality, his lack of 
fanaticism, and his respect for his opponents, he conquered Syria, 
Egypt, and most of modern day Israel steadily and without great 
difficulty. He was enormously respected by nearly all of his rivals, and
 maintained an epistolary friendship with Richard the Lionheart, sending
 him gifts, horses, and his own physician.
4. Robert E. Lee

Lee,
 perhaps the most successful commander in history against numerically 
and materially superior forces, was the gentle genius in charge of the 
Army of Northern Virginia and most Confederate forces during the Civil 
War. He developed a reputation of near omniscience among both enemies 
and allies, and soundly thrashed Union forces soundly on numerous 
occasions. His losses, few as they were, were generally more devastating
 to his opponents than himself, and Ulysses S. Grant, the only general 
to successfully corner Lee, was forced to adopt a strategy of attrition,
 rather than any attempt to outfight Lee.
5. George Washington

Washington
 was the pivotal, and probably most successful, leader of the American 
revolutionary forces vying for independence from the British Empire. 
Though ably assisted by several subordinates (including Benedict Arnold,
 whose military acumen has been overshadowed by his famous betrayal), 
Washington proved the uniting force of the Continental Army, leading it 
to victory at Trenton and Yorktown, and holding the piecemeal forces 
together in the hard winter at Valley Forge.
6. Julius Caesar

The
 famed consul of Rome was perhaps the ablest of the late Republic’s 
military leaders, vying with his co-consul, Pompey for glory in 
subjugating territory to Rome’s expansionist will. His campaign against 
the Gauls is still required reading in many military academies, and his 
defeat of Pompey nearly granted him the kingship of firmly republican 
Rome. The political and personal treachery that ended his life and 
provided the opportunity for his nephew, Octavian, to become emperor, is
 legendary, but Caesar’s successes were more reliant on the loyalty and 
victory of his armies than political maneuvering.
7. Joan of Arc

The
 maid of Orleans is the only commander on this list to have had to share
 command in even her finest moments of victory, but as she is also the 
only woman, one feels an exception is in order. A French peasant girl 
who claimed visions from God, she traveled to Charles II, the French 
king losing the war to the English. Though she was hampered by 
skepticism at first, Joan influenced several important French victories,
 leading charges personally, and inspiring French troops to renewed 
fervor.
8. George S. Patton

The
 most controversial figure of the Allied forces in WWII, Patton himself 
may have believed himself to be reincarnated from more ancient warriors,
 carrying their bravery and experience into his battles. A promising 
early career helping Pershing hunt Pancho Villa jumpstarted Patton into 
the armored corps, where he became a mentor to Eisenhower (later 
promoted over his head). In WWII, he gladly used the Germans’ blitzkrieg
 against them, using the maneuverability of American armored units to 
out maneuver German lines and gaining large amounts of ground over short
 periods of time. His infamous incidents, including troops under his 
command executing more than one massacre, and Patton’s slapping of a 
supposedly cowardly soldier in a field hospital, contributed to his 
decline, but more than anyone else, he led the Allies to victory in 
Europe.
9. Frederick the Great

Frederick
 II of Prussia was a student of modern warfare, and later its guiding 
voice in the late 18th century. He modernized the army of his disjointed
 pseudo-German kingdom, and fought continuous wars against Austria, the 
dominating power of the Holy Roman Empire at the time. Known for both 
his books and treatises on warfare, as well as leading troops into 
battle personally (he had six horses shot from under him).
10. Attila the Hun

Leader
 of the Hunnish empire that stretched from the borders of modern day 
France to the steppes of Russia, this thorn in the side of both Roman 
and Byzantine empires assembled a massive force of all the tribes and 
nations traditionally viewed as provincial savages – Huns, Goths, 
Ostrogoths, Vandals, and many more, and nearly conquered mainland 
Europe. In the template of other “barbarian” conquerors to come after 
him, like Genghis Khan, he showed the lie of assumed Western 
superiority; and whenever your enemies names you “the Scourge of God”, 
you can assume you’ve proved yourself a respected threat.
