The Principles of War are mostly defined as guidelines and “best practices” that have generally proven true throughout the history of warfare. The US Army for instance, currently recognizes nine principles of war, which are as follows [1]:
Objective
Offensive
Mass
Economy of Force
Maneuver
Unity of Command
Security
Surprise
Simplicity
Taken together, these principles help commanders plan for and conduct successful military operations. However, given moral forces and an obvious physical/human element to the history and character of warfare, one may beg the question… should morale be a principle of war?
Though it is curiously absent from US doctrine, morale has been a staple of warfare since the beginning, predating even strategy and tactics. Unit cohesion on the battlefield, not generalship, was what arguably contributed the most to victories in the great shoving matches between ancient and medieval armies – success going to the side who didn’t flee or surrender. In addition, morale is embodied in warrior ethos, which more often than not, relates back to a set of heroic ideas that allow a solider to overcome their natural fear of death – courage being the most important one. Finally, a strong argument can be made that many elite units (to include modern guard units), are not so much defined by their fighting prowess or equipment, but by their personal loyalty to the commander, their cause, and willingness to fight to the last man.
To quote Napoleon; “an army's effectiveness depends on its size, training, experience, and morale, and morale is worth more than any of the other factors combined.” A lesson that certainly proved true during the mass desertions that resulted from the Russian campaign, and repeated again centuries later when ISIS routed a modern Iraqi Army.
Yet one of the strongest arguments that can still be put forward in favor of morale are the principles of Surprise and Security. If Surprise is a viable method of securing victory (via shock), and if Security means never letting the enemy acquire an unexpected advantage, then morale, and its effects on combat power, must be seen as a tested and true principle of war.
Where morale could come up short however, is that it is too often confused as a goal by inept military planners. The principles of war are meant to be means to an end (elements of strategy), whereas too often the morale of individuals soldiers, and its focus on well-being, are incompatible with actual military objectives. The achievement of specific collective goals, to include national interest, must come before a soldier’s mood and happiness.
A strategy based on esprit de corps is obviously no strategy at all.
Finally, if morale has been on the battlefield since the beginning, then so has weapons tech. Revolutions in military affairs mean that modern battlefields are more rapid, deadly, and decisive than ever before. The arrival of destructive ordnance and mechanized armies (to include high-speed standoff weaponry) is in effect the arrival of perfect soldiers, impervious to fear and fatigue, who obey orders and can kill without question. Though moral forces have always been linked to our ability to resist, the awesome and destructive power of physical force means are feelings on the matter are less important than ever.
In short, morale may have driven soldiers to fight, to stick around and give it their all in the face of overwhelming odds, but in the end, unlike the other principles of war, it probably won’t save him.
Unit dispersion, not cohesion, is now the best means to insure victory and survival.
