I carefully read with a great deal of interests all these posts expressing a wide variety of insights as to the greatest military battlefield commanders and/or tactical generals in world history. Although I agree with most of you in terms of the many tactical geniuses noted from the early ages with Alexander the Great and Julius Caesar to more modern times with Napoleon to Rommel, I do think two distinctions should be made. First, time periods. I do not think it is practical to compare tactics of modern warfare with those in ancient times. Finally, I think we should also look at tactical area of operations (land, sea, and since World War II, air). Certainly there are differences between sea and land tacticians.
Although several of you made “honorable mention” of General Nathan Bedford Forrest, I think he would at least make the top 10 list of best generals in world history. And for me, he is first on my list.
In the American Civil War, Nathan Bedford Forrest enlisted as a private in the Confederate Army. During his brief military career, he obtained the rank of Lieutenant General. He was the only man in either army to rise so far. In addition to his success, he was no “war room” or “tent operations general” (like Generals Omar N. Bradley and Robert E Lee, or Field Marshal Walther Model). In fact, Forrest was wounded four times in battle, killed thirty union soldiers in hand-to-hand combat, and had twenty-nine horses shot out from under him. His famous saying was, "War means fightin', and fightin' means killin'."
The military character of General Forrest, apart from questions of his battlefield skills, horsemanship and special wit at tactics, was admittedly that of a great leader. Although he was never formally educated in military tactics and strategies, he defeated every West Point graduate he encountered on the battlefield. His personality and his natural gift as a warrior were such that General Sherman considered him the most remarkable man the Civil War produced on either side.
General Sherman (the real butcher) said that he would get "that devil Forrest" if it cost him 10,000 soldiers and broke the US treasury. His engagement of Federal troops at Brice's Crossroads on June 10, 1864 is considered by many the perfect battle. Union Major General Samuel D. Sturgis, with more than 8,000 men was marching south into northern Mississippi to block the cavalry from attacking Sherman's supply lines. When Sturgis ran into Forrest's dismounted horsemen he assembled a perimeter around the crossroads. Forrest flanked him on both sides, the same double envelopment that worked so well near Bowling Green. In the words of civil war historian Shelby Foote,
"In his first fight, northeast (sic) of Bowling Green, the forty year old Forrest improvised a double envelopment, combined it with a frontal assault-classic maneuvers which he could not identify by name and of which he had most likely never heard..."
The bluecoats ran. A bridge over the Tishomingo Creek became a roadblock for the retreating army and ever vigilant for such opportunity, the Confederate general pounced. Sturgis would later write, "What was confusion became chaos..." as the rebels pounded the fleeing blues. With less than three thousand men Forrest had destroyed an enemy more than twice the manpower with superior firepower and weapons. This brilliant tactical victory against all odds cemented Forrest's reputation as one of the foremost mounted leaders of the war.
As for General Forrest's military record on battlefield tactics, it cannot be denied or downplayed. After the surrender of the South, when asked by a senior Union Officer who he thought his greatest general was, General Robert E. Lee replied, "Sir, that would be a gentleman who I have never had the pleasure of meeting, General Nathan Bedford Forrest." Field Marshall Erwin Rommel (the Desert Fox), studied Forrest's battle tactics as did the U.S. Army's “Ole Blood and Guts" General George S. Patton, and General “Stormin” Norman Schwarzkopf. The Institute for Military Studies concluded that the Battle of Brice's Crossroads (won by Forrest) was perhaps one of the most spectacular displays of tactical genius in history.
Just as an added note before closing, Forrest's grandson, Nathan Bedford Forrest III, also followed a military career reaching the rank of Major General in the U.S. Army during World War II before being killed in action in 1943.
