Napoleon was the Best General Ever, and the Math Proves it.

The Method

Inspired by baseball sabermetrics, I opted to use a system of Wins Above Replacement (WAR). WAR is often used as an estimate of a baseball player’s contributions to his team. It calculates the total wins added (or subtracted) by the player compared to a replacement-level player. For example, a baseball player with 5 WAR contributed 5 additional wins to his team, compared to the average contributions of a high-level minor league player. WAR is far from perfect, but provides a way to compare players based on one statistic.

I adopted WAR to estimate a given military tactician’s contributions beyond or below an average general. My model, which I explain below, provides an estimate for the performance of an average general in any given circumstances. I can then evaluate a general’s quality based on how much they exceeded or fell short of a replacement general in the same circumstances (assuming a replacement general would perform at an average level). In other words, I would find the generals’ WAR, in war.

The Results

Among all generals, Napoleon had the highest WAR (16.679) by a large margin. In fact, the next highest performer, Julius Caesar (7.445 WAR), had less than half the WAR accumulated by Napoleon across his battles. Napoleon benefited from the large number of battles in which he led forces. Among his 43 listed battles, he won 38 and lost only 5. Napoleon overcame difficult odds in 17 of his victories, and commanded at a disadvantage in all 5 of his losses. No other general came close to Napoleon in total battles. While Napoleon commanded forces in 43 battles, the next most prolific general was Robert E. Lee, with 27 battles (the average battle count was 1.5). Napoleon’s large battle count allowed him more opportunities to demonstrate his tactical prowess. Alexander the Great, despite winning all 9 of his battles, accumulated fewer WAR largely because of his shorter and less prolific career.

However, outside of Napoleon’s outlying success, the generals’ WARs largely adhere to a normal distribution. This suggests his success is attributable to command talent, rather than an anomaly in the model’s findings. In fact, Napoleon’s total WAR was nearly 23 standard deviations above the mean WAR accumulated by generals in the dataset.

There were also generals that had surprisingly low total WAR despite a reputation as master tacticians. Robert E. Lee, commander of the Confederate States Army, finished with a negative WAR (-1.89), suggesting an average general would have had more success than Lee leading the Confederacy’s armies. Lee was saddled with considerable disadvantages, including a large deficit in the size of his military and available resources. Still, his reputation as an adept tactician is likely undeserved, and his WAR supports the historians who have criticized his overall strategy and handling of key battles, such as ordering the disastrous ‘Pickett’s Charge’ on the last day of the Battle of Gettysburg. In the words of University of South Carolina professor Thomas Connely, “One ponders whether the South may not have fared better had it possessed no Robert E. Lee.”

German field marshal Erwin Rommel, nicknamed the ‘Desert Fox’ for his successes in North Africa during World War II, also performed poorly in this model, finishing with -1.953 WAR. This finding disputes the praise Rommel has received as a tactician from modern generals, including Norman Schwarzkopf and Ariel Sharon. However, like Lee, Rommel has been the subject of considerable historical debate. In particular, critics have attributed much of his reputation as a tactical genius to both German and Allied propaganda. British generals reportedly exaggerated Rommel’s tactical abilities in order to minimize disapproval regarding their defeats.

Modern generals performed relatively poorly in the model. American general George S. Patton, described by historian Terry Brighton as “among the greatest generals of [World War II],” accumulated only .9 WAR. The failure of modern generals to perform well in WAR may be attributable to changes in warfare which have prevented individual generals from participating in a large number of battles.

Among post-World War II generals, Israeli commanders stood out. Israeli military leader Moshe Dayan finished with 2.109 WAR (60th overall), an impressive amount for a modern general but relatively modest compared to pre-20th Century tacticians. Similarly, former Israeli Prime Minister Ariel Sharon accumulated 2.171 WAR (58th overall) for his battlefield successes in the Suez Crisis, Six-Day War, and Yom Kippur War.

Finally, I compared Hannibal’s assessment of the top generals of all time to my model. According to WAR, Hannibal underrated his own abilities— of all generals to date, Hannibal had the highest WAR at 5.519 (6th overall). Alexander the Great, who Hannibal named the top general, was just behind Hannibal’s mark with 4.391 WAR (10th overall). However, Alexander died after fighting just 9 battles, winning all of them. Hannibal had 17 battles to accumulate value, winning 13, losing 2, and drawing 2. Thus, I agree with Hannibal’s assessment that Alexander was the more able tactician, even though Hannibal provided more total value — Alexander demonstrated his ability to win battles, and likely would have continued to win had he not succumbed to illness.

My findings starkly diverge from Hannibal’s assessment regarding Pyrrhus of Epirus, a Greek general and early Roman rival. My model credits Pyrrhus with only 3 battles and -0.53 WAR. Although Hannibal attributes innovative military tactics to Pyrrhus, I am deeply skeptical of his overall tactical acumen, even before considering his inability to prevent catastrophic casualties to his armies during his victories.
