time. For this outcome Nathanael Greene deserves much of the credit. He had gone south and reversed a losing campaign. And he did so against skillful generals in command of veteran troops, in a theater of operations in which a third of the population actively supported the British and another third simply wished to stay out of harm’s way. But it is the manner in which Greene achieved his results that is most distinguishing, in particular his masterful mixing of conventional and irregular operations. As a strategist he had an innate understanding that irregular warfare often demanded that the principles of war be violated, so in the face of a superior enemy he boldly divided his own forces. Later he would march away rather than toward the main enemy army, opening the door to Cornwallis’s invasion of Virginia. The sheer audacity of these moves was further compounded by his willingness to face British forces in pitched battles time and again. Although Greene was careful enough to break off the fighting and retreat from the field when the risk was too great that his army might be broken, such judgments are hardly subject to precise calculation. The very fact that he took the field in this manner meant that, on any given day of battle, he could have lost all. Without the willingness to take such risks, Greene would not have empowered the guerrillas working with him. Unless he could divert the British with his main force, his irregulars might be hunted down by Banastre “Bloody Ban” Tarleton and other well-practiced irregular hands among the empire’s forces. That the British and their German mercenaries had developed a keen sense of the demands of counterinsurgency is reflected in the classic memoirs of Johann Ewald, who conducted many such operations during the war. In his DIARY OF THE AMERICAN WAR: A HESSIAN JOURNAL and his TREATISE ON PARTISAN WARFARE Ewald noted the potency of the insurgents but also their vulnerability to countermeasures when no friendly regular forces were nearby. Greene was well aware of this too, and no doubt was willing repeatedly to risk the loss of his Continental regulars because the failure to do so would almost certainly lead to the withering away of insurgent forces. Nevertheless it took far more than cold-blooded strategic logic to follow such a campaign plan. It also required great courage, not only on the battlefield but in counsels of war. Greene had shown his fearlessness in firefights many times before and knew that a leader had to be an exemplar. On one occasion this duty led him calmly to continue writing dispatches sitting at his open tent while Cornwallis—who had just missed catching Greene at a river crossing—was in frustration bombarding the rebel camp with artillery he had drawn up right to the water’s edge on the opposite shore. But it must have taken Greene just as much courage to make his daring decisions to divide his inferior force and to march away from Cornwallis, allowing the latter an open road to Virginia. It is Greene’s strategic courage that stands out as exceptional in American military history. There has been no lack of brave field generalship over the past two centuries and more. But the kind of command boldness that he showed remains unusual and, when it comes to the irregular, in the words of Russell Weigley Greene, “remains alone as an American master developing a strategy of unconventional war.” 14 Do high-level British strategic disputes and errors diminish Greene’s achievements? Not at all. The very fact that Greene persisted against superior forces and skillful enemy generalship was what drove Cornwallis to launch his own controversial move northward. His dispute with Clinton does not weaken the case for Greene’s mastery, for it is the mark of a master that the enemy is placed in such uncomfortable positions in the first place. In any event, military campaigns that proceed without errors are nearly nonexistent. The true mark of mastery is
