Principled Warfare: Episode 4: The New Principles

And here we are, having completed the first 9 Principles of Joint Operations (HERE, HERE, and HERE). Today we’ll look at the 3 new Principles, but first a few words about how these have come about and how the military uses them. 

As I said in the first post, we owe the idea of Principles of War (what the first 9 used to be known as) to Baron Anton de Jomini, a Swiss banker turned military officer in Napoleon’s army. Jomini is really the first in Western military history to articulate a set of rules to follow (“Principles”) in the conduct of warfare. Nowadays Clausewitz is more popular and Jomini’s “scientific” approach is criticized as creating merely a “cookbook” for warfare rather than the more intellectual musings of his German counterpart, but in the 1800’s Jomini’s work was the basis for much of the teachings of armies all over the world, including the US Military Academy at West Point; all of the generals on both sides of the US Civil War were brought up studying Jomini. Today, much of what we as the US military study is a blend of Jomini’s “science” and Clausewitz’s “art”. The 9 Principles we’ve studied so far that were previously called the “Principles of War”, while not all concepts articulated by Jomini, directly follow his orderly approach. 

Napoleon and his staff. Jomini is probably in the back somewhere.
Jomini formulated his concepts based on his experiences in the Napoleonic wars. While you could find plenty of irregular warfare similar to modern day counterinsurgency (the Peninsular Campaign in particular stands out), it is the experience in large, conventional battles that shaped Jomini’s thoughts.  Like Jomini, military thinkers up through the Cold War thought mostly in terms of large-scale, conventional warfare, with two opposing armies fighting battles as instruments of national power. In the post-Cold War world, military thinkers started to pay attention to smaller wars and irregular warfare, developing concepts like MOOTW (Military Operations Other Than War) and LIC (Low-Intensity Conflict). 

Obviously the old 9 Principles all are still valid, and indeed can be applied to non-lethal means. They can even translate outside of warfare—for instance, those of you bombarded by beer company ads while watching sports are the targets of advertising agencies MASSING their effects on their target audience to maximize revenue; putting commercials for kid’s toys during football games would miss the target audience and violate ECONOMY OF FORCE because it’d be a waste of money. And so we get beer commercials during football and My Little Pony during cartoons. 

However, it is the US/NATO experience in Iraq and Afghanistan, and mostly the failures of methods designed for conventional warfare to lead to success in a counterinsurgency (COIN) environment, that highlighted the need to rethink how we did things. Simply rolling in and blowing everything up is not an effective way to get a populace on your side, and if you’re trying to defeat an insurgency rather than conquer a country, you have to have the populace (and the international community, not to mention your own citizens) on your side. Hence, we now have added three new Principles to the original nine. We’ll start with the Principle of Restraint. 

Restraint[1]

(1) The purpose of restraint is to limit collateral damage and prevent the unnecessary use of force.

(2) A single act could cause significant military and political consequences; therefore, judicious use of force is necessary. Restraint requires the careful and disciplined balancing of the need for security, the conduct of military operations, and the national strategic end state. For example, the exposure of intelligence gathering activities, such as interrogation of detainees and prisoners of war, could have significant political and military repercussions and should be conducted with sound judgment.  Excessive force antagonizes those parties involved, thereby damaging the legitimacy of the organization that uses it while potentially enhancing the legitimacy of the opposing party.

(3) Commanders at all levels must ensure their personnel are properly trained─including knowing and understanding ROE (Rules of engagement)─and are quickly informed of any changes. Failure to understand and comply with established ROE can result in fratricide, mission failure, and/or national embarrassment. Restraint is best achieved when ROE issued at the beginning of an operation address most anticipated situations that may arise. Since the domestic law of some nations may be more restrictive concerning the use of force than permitted under coalition or allied force ROE, commanders must be aware of national restrictions imposed on force participants.

Restraint is most easily described through the example of targeting: you don’t take out an entire city block with a JDAAMS bomb to get one guy, because the collateral damage (innocent bystanders killed, property damage, etc.) is more detrimental to your cause than anything one person could do to you. Sure, you’ve eliminated one terrorist, but you’ve probably just created 30 more, as every relative of someone killed and every person who just lost their home is now angry with you and at least going to side with the enemy over supporting you. 

I can see the wheels turning in some of your heads—how, exactly, is Nate going to connect this to the samurai? After all, samurai weren’t exactly out to win the hearts and minds of the populace. Samurai warfare was a bloody force on force conflict, and we all are familiar with the stereotype of samurai committing suicide rather than being captured or surrendering. It doesn’t appear there was much room for restraint on the Sengoku battlefield.
 
I would agree with this for the most part. However, I think I can illustrate the importance of restraint by comparing Oda Nobunaga to his successor Toyotomi Hideyoshi, specifically how they dealt with daimyo who opposed them. 

"Bloodshed Demon Nobunaga" is an example of Nobunaga's reputation
Nobunaga is well known for his lack of restraint in dealing with enemies. While to say he always stamped out his defeated foes is a gross over-generalization, in general he was fairly harsh in dealing with those who opposed him. His treatment of defiant religious groups—primarily the ten year war against the Ishiyama Honganji and the complete destruction of the Enryaku-ji Temple on Mt. Hiei and the murder of every man, woman, and child on the mountain –stand out as brutal examples of how Nobunaga dealt with any forms of resistance to his authority. The wholesale destruction of the province of Iga is another example. Nobunaga’s brutality made opposing him a choice not taken lightly, for sure. However, the scale of that brutality meant that once a daimyo or other entity made that choice, they had to resist Nobunaga to the death; there was no way to change your mind and surrender, as once you opposed Nobunaga, he was determined to annihilate you. (As I said, this is an oversimplification, as there are examples where this isn’t true, but for the most part it works).

Especially after 1575, Nobunaga was powerful enough in central Japan that he could afford not to practice restraint. It possibly bit him, however, when he was assassinated by Akechi Mitsuhide. Since to oppose Nobunaga meant you would face his full wrath with no mercy, the only way to oppose him successfully was to attack him when you could destroy him. This opportunity presented itself to Mitsuhide in June of 1582, when Oda Nobunaga and his small force of body guards were overwhelmed by Mitsuhide’s army at Honno-ji in a surprise attack at dawn. Mitsuhide didn’t exactly have the option of withdrawing from Nobunaga’s service and going somewhere else. 

Now, let’s look at Toyotomi Hideyoshi. Hideyoshi, of course, crushed Mitsuhide at Yamazaki and was able to claim certain rights as Nobunaga’s avenger, but he lacked the inherent power that Oda Nobunaga had. He could not simply crush everyone who stood in his way. Yet within 2 years of Nobunaga’s death, Hideyoshi had not only consolidated control over Nobunaga’s territory but was expanding it at a much faster rate than Nobunaga ever did. By 1590, a mere 8 years after Nobunaga’s death, Hideyoshi had complete control of all of Japan. How? Well, paradoxically, by using restraint. 

Unlike Nobunaga, Hideyoshi always gave his opposition a way out of conflict. Beginning with the Mori right after Nobunaga’s death, Hideyoshi would follow a pattern of reconciliation and integration. Those that chose not to submit (Shibata Katsuie, for example, in 1583, or the Hojo in 1590) would be obliterated, but any daimyo that confronted Hideyoshi was given the option to surrender and retain at least a little of what they held rather than face complete destruction. Tokugawa Ieyasu in 1584, the Chosokabe on Shikoku, then the Shimazu on Kyushu, all initially opposed Hideyoshi, only to be defeated (Tokugawa Ieyasu actually won against Hideyoshi at Nagakute/Komaki, but submitted when he saw that no matter how many battles he won, Hideyoshi had material and manpower superiority and would eventually overwhelm him).  Once Hideyoshi demonstrated his superiority and capability to annihilate his enemy, he gave them the option of joining him. Some daimyo had their lands reduced (the Shimazu were pushed back into southern Kyushu, the Chosokabe had to give up all of Shikoku other than Tosa province) but some actually benefitted (Ieyasu eventually gave up his home provinces of Mikawa and Totomi, but gained the much larger territory around Edo in the Kanto). In either case, the daimyo were given an out that allowed them to keep their heads, some land, and then gain position within Hideyoshi’s political structure. Eventually, even daimyo not directly confronted by Hideyoshi’s armies (like the Date of northern Japan) saw it was best to preemptively submit to his control. By not following a pattern of total destruction like Nobunaga, Hideyoshi was able to build a coalition of daimyo loyal to him and obtain control of all of Japan in only 8 years. This is a textbook example of strategic restraint.[2]

Perseverance

(1) The purpose of perseverance is to ensure the commitment necessary to attain the national strategic end state.

(2) Perseverance involves preparation for measured, protracted military operations in pursuit of the national strategic end state. Some joint operations may require years to reach the termination criteria. The underlying causes of the crisis may be elusive, making it difficult to achieve decisive resolution. The patient, resolute, and persistent pursuit of national goals and objectives often is essential to success. This will frequently involve diplomatic, economic, and informational measures to supplement military efforts.

Perseverance means keeping up the fight until the other guy buckles. The North Vietnamese did not defeat the US tactically, by far taking the worst of the fighting throughout the entire Vietnam War. However, they had more national will to persevere than the American public did, and outlasted the United States despite their significant tactical disadvantages. Enemies before and since—the Japanese in WWII felt they could force the US to surrender because the American public would not accept heavy casualties, as do terrorist and anti-US forces in Iraq and Afghanistan today—have tried the same approach. The difference in those two cases is that Pearl Harbor and 9-11 so inflamed the US public that the will to continue the fight and persevere was there. (The question remains open in Afghanistan 11 years after 9-11, but this illustrates the point.) Perseverance is the main weapon of any insurgency against a superior power, usually because it is significantly outgunned and outmanned. Insurgencies win when they persevere and demonstrate that the governmental power is unable to destroy them and therefore weak or illegitimate; they fail when the stronger power has the will and perseverance to hunt them down.

Two examples will demonstrate this in Japanese history. First, Nobunaga successfully defeated what may best be described as a religious insurgency in his ten-year campaign against the Ikko Ikki and the Ishiyama Honganji. The Ikko sectarian movement, which rejected secular daimyo control in favor of fanatical obedience to their religious leaders at the Ishiyama Honganji temple in Osaka, in many ways, threatened the political order itself, not just Nobunaga’s control of it. A surviving Ikko Ikki meant that a challenge to samurai control of the populace existed. Consequently, Nobunaga could not allow it to exist if he intended to consolidate national political control. Over a period of ten years, Nobunaga fought, blockaded, besieged, and rooted out Ikko supporters in various areas of the country. At times he engaged the Imperial Court to broker cease-fires, in order to give him time to reconsolidate and refit his forces in preparation for the next round of fighting (or to go fight other threats elsewhere, but I digress…). Even in these peaceful lulls, the endstate—the destruction of this religious entity outside of samurai political control—was never abandoned. Nobunaga, as the political hegemon, persevered through obstacles to eventually bring the Ishiyama Honganji to the point of surrender in 1582.

It may seem like this is no big deal—after all, Nobunaga was a dictatorial daimyo who didn’t have to answer to the public, didn’t have reporters documenting things and questioning him like the American military in Vietnam, and didn’t really have to care what other “nations” thought of how he handled the Ikko Ikki. Of course he could persevere, you might say, because he didn’t have anything to keep him from doing so. That would be ignoring the complexity of the campaign against the Ikko Ikki (with campaigns against them fought in three separate geographic regions, the need to dismantle their multi-ringed defenses around the Ishiyama Honganji, and the need to separate them from their supporting allies the Mori and others, on top of fighting other daimyo threats in three different theaters of war). For a counterpoint to that argument, I will show a successful insurgency in Japanese history, outside of the Sengoku period.

Kusunoki Masashige's Statue in Tokyo
Kusunoki Masashige, famous as the paragon of loyalty for his dedication to the cause of Emperor Go-Daigo and his struggle against the failing Kamakura bakufu government, is the quintessential insurgent leader. Masashige never struck a crushing blow against Kamakura forces. His success was in surviving. By confounding and eluding government forces in the mountains south of Kyoto, he demonstrated the ineffectiveness of the Kamakura regime for the rest of Japan, especially the leaders of warrior houses, to see. Kamakura’s control rested on the assumption that the Shogun (or rather the Hojo regents who ran the government) maintained military control over the country. Kusunoki’s resistance and defeat of pursuing government forces at Chihaya and Akasaka didn’t militarily or economically cripple the Kamakura regime. What it did, though, was demonstrate that resistance to Kamakura was a possibility. And so, when the first armies sent out to defeat Kusunoki failed, Kamakura sent more armies—armies led by a man named Ashikaga Takauji, and Nitta Yoshisada. Takauji’s army went west, but instead of engaging and defeating Kusunoki, switched allegiance to Go-Daigo and secured the capital region for his return. Nitta Yoshisada’s army turned east back to Kamakura and attacked the government headquarters, destroying the bakufu capital and the Kamakura government once and for all in 1333. Kusunoki’s perseverance and ability to stay alive led to this (temporary) victory. That the successful commanders fell out and eventually fought each other, with Ashikaga Takauji defeating Nitta and Kusunoki in 1336 to take control of Japan, should not diminish from the value of perseverance. In fact, Takauji himself would make a great case study in perseverance—defeated early on, retreated to the ends of Japan (Kyushu), only to gather strength again, return to defeat Kusunoki and Nitta, retake Kyoto and declare himself Shogun, then later forced out by his own brother before returning and defeating him for control of the Shogunate.

One last note on perseverance: the old saying describing Japan’s three unifiers states that Nobunaga sewed and picked the wheat, Hideyoshi pounded the flour and baked the bread, and Ieyasu ate it. Tokugawa Ieyasu started as an underling of the Imagawa, became the junior ally of Nobunaga after Nobunaga defeated the Imagawa, challenged Hideyoshi after Nobunaga’s death only to submit to him, and then eventually outlived Hideyoshi and destroyed his son to found his own shogunate which lasted 250+ years. THAT is perseverance.

Legitimacy

(1) The purpose of legitimacy is to maintain legal and moral authority in the conduct of operations.

(2) Legitimacy, which can be a decisive factor in operations, is based on the actual and perceived legality, morality, and rightness of the actions from the various perspectives of interested audiences. These audiences will include our national leadership and domestic population, governments, and civilian populations in the operational area, and nations and organizations around the world.

(3) Committed forces must sustain the legitimacy of the operation and of the host government, where applicable. Security actions must be balanced with legitimacy concerns. All actions must be considered in the light of potentially competing strategic and tactical requirements, and must exhibit fairness in dealing with competing factions where appropriate. Legitimacy may depend on adherence to objectives agreed to by the international community, ensuring the action is appropriate to the situation, and fairness in dealing with various factions. Restricting the use of force, restructuring the type of forces employed, and ensuring the disciplined conduct of the forces involved may reinforce legitimacy.

(4) Another aspect of this principle is the legitimacy bestowed upon a local government through the perception of the populace that it governs. Humanitarian and civil military operations help develop a sense of legitimacy for the supported government. Because the populace perceives that the government has genuine authority to govern and uses proper agencies for valid purposes, they consider that government as legitimate. During operations in an area where a legitimate government does not exist, extreme caution should be used when dealing with individuals and organizations to avoid inadvertently legitimizing them.

Today, legitimacy is about doing what the world—the international community, our own public, and obviously the local nationals in the country we are involved in—will perceive as moral, just, and right. The other two Principles today play into this—if we use too much force and do not show restraint, then that undermines our legitimacy; if we don’t “stay the course” (persevere) and we “cut and run” as soon as things get tough, that undermines our legitimacy in a different way.

It would be easy to think that, like with restraint, legitimacy would not matter to a samurai daimyo of the 16th century. After all, CNN was not there to document the war atrocities committed by Hideyoshi’s troops against the Koreans, or Nobunaga’s troops against the Enryakuji, and even if they were, times were different and it’s not as if Nobunaga or Hideyoshi had to worry about public approval ratings. Or did they?

I would argue that samurai daimyo, especially those seeking national power, were obsessed with legitimacy. There was a voting public they to which they had to demonstrate competency and right to rule—their warrior subordinates. No, they didn’t go to the polls and cast a vote, but they could certainly vote with their feet (or their swords) and overthrow a weak leader who did not make efforts to seek legitimacy. So, in that regard—what WAS legitimacy, in the 16th century?

Consider the fact that, despite the turbulent history and almost constant fighting for control of Japan from the Gempei War in the 1180’s through the Osaka Campaign of 1615, at no time did any samurai leader attempt to militarily supplant the Imperial institution. (Theories exist about Ashikaga Yoshimitsu having the idea around 1400, but there’s no smoking gun that says he actually intended to remove the emperor and assume the title of emperor himself.) Why not? Well, the Emperor was a god—or at least Shinto Nationalism from the pre-WWII era would tell us. How much that was actually believed prior to the Meiji era is up for debate, but the fact remains that the emperor was a symbol of divine rule, whatever his personal status as a deity.

Jimmu Tenno, the first Emperor
This symbolism was hereditary—the emperors descended from Jimmu Tenno, the son of the Sun Goddess—and therefore a samurai warlord could not just waltz into Kyoto and take over the title of emperor, since he didn’t have divine DNA. Force alone wouldn’t do the job. Therefore, political control in Japan, from the time of the Soga and Fujiwara in the Nara and Heian periods through the end of the WWII, rested on the approval and authority (willingly given or not) of the emperor. Recognition by, or control of, the emperor was the difference between being a rebel or being a suppressor of rebels. Gaining court titles, whether or not any material value was included (and after the Heian period usually no land or stipend was attached to titles, but that’s a whole different series of blogposts), gave valuable legitimacy to the holder of the title. This is why samurai warlords fought from the beginning of samurai warfare. The Taira’s legitimacy came in the form of Kiyomori named as regent; the Minamoto restructured things when Yoritomo set up the Shogunate and make Shogun the preferred title for exercising national warrior control. The Ashikaga fought first Kamakura and then Go-Daigo to claim the title of Shogun for themselves, going so far as to set up an alternate successor to the Imperial line as a challenger to Go-Daigo. Some military rulers even leveraged control of the shogun without becoming shogun themselves—the Hojo regents of Kamakura or the Hosokawa Kanrei under the Ashikaga legitimized their control of the government by being “servants and stewards” of the bakufu, under the authority of the weak but legitimately recognized shogun.

We see the same patterns in the Sengoku period. Oda Nobunaga, as did most daimyo, developed ties with the Shogun early in his career, even visiting Ashikaga Yoshiteru in Kyoto, according to biographies. When Nobunaga began to look towards achieving national prominence, he found his legitimacy in the goal of restoring Ashikaga Yoshiaki, the brother of the assassinated Yoshiteru, to Kyoto as the heir to the Shogunate. Nobunaga only removed Yoshiaki from power once he had enough power of his own to be legitimate, and according to Lamers[3], did everything he could to maintain good relations with Yoshiaki. After removing Yoshiaki, Nobunaga established direct ties to the Imperial court, who would reward him with titles further legitimizing his central rule.

After Nobunaga’s death, Hideyoshi masterfully used the court to legitimize his military rule. Like we talked about before, Hideyoshi did not really start with an independent power base or a formidable military strength capable of imposing his will on his enemies. The same was true of his relations with the Imperial court. Recognizing the disadvantages of his humble birth, Hideyoshi had himself adopted by a Fujiwara family court noble, instantly giving him a “pedigree”, and adopted the name Toyotomi, associated with the Fujiwara family. This new “lineage” then allowed him to assume titles traditionally assigned to the Fujiwara family—namely, Kampaku (Imperial Regent). While many today assume Shogun to have been a higher title because most military rulers used that title, Kampaku was actually much higher on the prestige scale, especially when also paired with the title of Daijo Daijin (Prime Minister); Hideyoshi held both titles. Of course, titles were not dispensed just because he got himself adopted by the right people. He had to have the military strength and the savvy to demonstrate the power to rule, but the point is no matter how much military power a daimyo had, he still had to rule under the mantle of Imperial sanctioned legitimacy.

Well, that concludes our look at each of the Principles of Joint Operations. Next week I’ll return with a look at how they can be used to inform military historical analysis through a case study of a particular battle. You’ll never guess which one that might be….

Principled Warfare II: Samurai Combat Done Right (And Wrong)


Welcome to installment 2 of our 5 part series on the Joint Operating Principles and their application to pre-modern Japanese warfare. Go here for the Introduction and Part One of the series, where I examined the Principles of Objective, Offensive, and Mass. Today we’ll look at Maneuver, Economy of Force, and Unity of Command. Since I already did the explanation of what we’re doing in the first post, I’ll just jump into it today.

Maneuver

(1) The purpose of maneuver is to place the enemy in a position of disadvantage through the flexible application of combat power.

(2) Maneuver is the movement of forces in relation to the enemy to secure or retain positional advantage, usually in order to deliver—or threaten delivery of—the direct and indirect fires of the maneuvering force. Effective maneuver keeps the enemy off balance and thus also protects the friendly force. It contributes materially in exploiting successes, preserving freedom of action, and reducing vulnerability by continually posing new problems for the enemy. [1]

Every military commander wants to be in the best position to attack and destroy the enemy. Sometimes that means moving around to the side or rear and surprising him; sometimes it means getting to a certain place, like the defensible high ground, first before the enemy so you have the advantage that location gives you. The way this is done is through maneuver, which as the second bullet says is moving in relation to the enemy to gain the advantage. Like in a wrestling (or judo, or whatever) match, you want to pin your opponent and prevent them from escaping while at the same time being free yourself to move how you want.

The first example for maneuver that we’ll look at is the engagements between the Uesugi and Takeda at Kawanakajima. While everyone remembers the violent and bloody 4th Battle of Kawanakajima in 1561, it is important to keep in mind that the two sides faced off at the same location three times before that (1553, 1555, 1557), and one time after (1564). In each of these other contests, the opposing armies withdrew after posturing and minimal combat. What was the difference between these four engagements and the 1561 battle? Maneuver...or rather, lack thereof.

In the first three engagements, both sides arrived at Kawanakajima (a plain in northern Shinano province, which now is the location of Nagano City) and took up defensive positions on high ground on either side of the plain. The terrain is such that neither side could venture into the center without exposing itself to attack, and neither side could determine a way to maneuver around the enemy’s flank without abandoning its defensive position. Consequently, after sitting for a while and watching each other, both Kenshin and Shingen would realize the other wasn’t going to make a mistake and move, and so they would retreat to conduct operations elsewhere.

Takeda Forces Maneuver Across the River at Kawanakajima
4th Kawanakajima, however, is different, because at the 1561 contest, one side concocted a scheme to tactically maneuver and gain an advantage. It’s interesting to note that the sides in this engagement were quite larger (20,000 Takeda vs 12,000 Uesugi, about 40% more on each side) than previous battles. Why is this important? Because with 20,000 troops, Takeda Shingen had enough that he felt he could split his force in two, maintaining some defense on the hills to the south of the Kawanakajima plain while maneuvering a force around the hills the Uesugi occupied to the north, attacking them from the rear and catching them between his two forces. He understood he needed to move his forces, or maneuver, to put them in a position of advantage relative to the Uesugi. 

Unfortunately for Shingen, Uesugi Kenshin saw what he was doing, and also maneuvered his force to take advantage of the situation. Kenshin moved under the cover of darkness from his positions on the high ground down to the valley below and attacked Shingen’s weakened position, almost overrunning it before the detached force that was supposed to surprise the Uesugi arrived to salvage what was becoming a Takeda defeat. Historians debate who was the victor in this battle (for the record, the Uesugi clearly won a tactical victory in my eyes, as they destroyed a higher percentage of the Takeda force than they lost, and defeated Shingen’s tactical plan), ultimately it doesn’t matter as the end operational and strategic result was the same as the previous battles—both sides retreated with no strategic or operational gain. The 1564 battle was a return to the previous pattern, with both sides setting up defensive positions, observing the other side, and eventually withdrawing. I guess Shingen and Kenshin had learned their lesson three years previously.

Fighting at Yamazaki, 1582
Another example of maneuver (among other things) winning a battle is the 1582 Battle of Yamazaki between Hashiba (later Toyotomi) Hideyoshi and Akechi Mitsuhide. If you’ll recall, Mitsuhide had just assassinated Oda Nobunaga, hegemon of central Japan, 13 days earlier and effectively controlled the capital of Kyoto. No rivals were in position to stop his takeover, as they were all engaged fighting Nobunaga’s campaigns in other theaters. Hideyoshi completed a hasty peace with the Mori, whom he was beating pretty badly at this point, and rushed his forces back to the capital region to engage the Akechi. While we can travers his route from the Okayama area to Kyoto now in an hour or two on the bullet train these days, for him to end fighting, negotiate a peace settlement, and turn his 20,000 man army around and march them all the way to Yamazaki to encounter Mitsuhide’s force is staggeringly impressive. His ability to maneuver completely took Mitsuhide by surprise and gave him considerable advantage.

At the tactical level, maneuver played a huge part at Yamazaki as well. The battle began as a race to the promontory of a mountain, as each side recognized that holding the high ground would be key to deciding the battle. Without going into too much detail, forces under Hideyoshi got their first, claiming the terrain and putting the Akechi forces at a distinct tactical advantage.

Economy of Force

(1) The purpose of economy of force is to expend minimum essential combat power on secondary efforts in order to allocate the maximum possible combat power on primary efforts.

(2) Economy of force is the judicious employment and distribution of forces. It is the measured allocation of available combat power to such tasks as limited attacks, defense, delays, deception, or even retrograde operations to achieve mass elsewhere at the decisive point and time.

This Principle boils down to using the bulk of your resources to accomplish those key tasks necessary for victory, and not on things that have little or no effect on the success or failure of the operation. To do otherwise is wasting your efforts. Consider attacking an enemy castle: if you have good security and are not worried about enemy forces coming from elsewhere to attack you from the rear, you would not leave half of your force to guard your supply train. A few soldiers left behind to raise any warning necessary and watch your horses would suffice, while the bulk of your army attacks the castle, to put the necessary mass (see, they all relate) in position (i.e., maneuver) to exploit the weak points in the enemy’s defenses. 

Ueda Castle, where Tokugawa Hidetada wasted time and did not practice Economy of Force!
Economy of force is perhaps best described through an example where it failed. During the 1600 Sekigahara campaign, Tokugawa Ieyasu charged ahead west with his main force to confront Ishida Mitsunari’s coalition in central Japan, meeting them in battle at Sekigahara in Mino province. Ieyasu’s son, Tokugawa Hidetada, was sent along a different route with 38,000 men to meet his father at the battlefield; together they would have had overwhelming force against the enemy. However, along the way Hidetada passed Ueda Castle, held by the Sanada family who opposed the Tokugawa, and he decided to attack it despite orders from his father to bypass it and hurry along to the main battlefield. Even though he only spent a short amount of time trying to take Ueda before he gave up and moved on, it was enough of a delay that Hidetada’s force missed the Battle of Sekigahara completely. Thankfully for the Tokugawa, due to other Principles we will discuss in a bit, the Tokugawa won the day and went on to rule Japan for over 250 years. However, Hidetada’s 38,000 troops were completely wasted, and could have been the difference between victory and defeat. You better believe Tokugawa Ieyasu let his son know this! 


Unity of Command

(1) The purpose of unity of command is to ensure unity of effort under one responsible commander for every objective.

(2) Unity of command means that all forces operate under a single commander with the requisite authority to direct all forces employed in pursuit of a common purpose. During multinational operations and interagency coordination, unity of command may not be possible, but the requirement for unity of effort becomes paramount. Unity of effort—the coordination and cooperation toward common objectives, even if the participants are not necessarily part of the same command or organization—is the product of successful unified action.

You’ve no doubt heard the phrases “Too many cooks spoil the batter” or “too many chiefs, not enough Indians”. These both allude to the fact that systems work best with one person in charge giving one vision for the rest to follow. This is why the military is not a democracy. Operations simply do not work if everyone involved gets to do their own thing. There must be one commander, and everyone has to work towards his objective for things to succeed.

Let’s return to Sekigahara for a perfect example of Unity of Command in action. On one side, you had Tokugawa Ieyasu, a clear leader. Respected by all, even his enemies, there was no doubt who was in charge of the eastern forces. Daimyo that chose to side with the eastern side were choosing to be led by Tokugawa Ieyasu; there was no challenge to his leadership.

On the western side, you had…well, you had a loose coalition. There were a variety of motivating factors for daimyo to choose the western side: loyalty to Toyotomi Hideyoshi’s memory, fear of Tokugawa Ieyasu, a vague sense of how things should be. One thing that wasn’t a motivation was strong coalition leadership. Ishida Mitsunari, the de facto head of the anti-Tokugawa, pro-Toyotomi forces, was generally disliked by most of the daimyo in the coalition. He was not seen as a strong leader, and was not even seen as an equal by many of the daimyo in the western coalition. Several prominent daimyo chose to join the Tokugawa, motivated by their hatred of Mitsunari (Kato Kiyomasa is the most notable example); changing the political leadership of the country was preferable to having to work with “that guy”. Though in command, Mitsunari wasn’t even the “head” of the western coalition; that fell to Mori Terumoto, who wasn’t present at Sekigahara, and who was a representative of Toyotomi Hideyori, the seven year old heir of the late Hideyoshi.

This lack of unity of command for the western forces seriously hampered their efforts. Several daimyo delayed their movement east towards the campaign; some, tasked to besiege and take Tokugawa held castles west of Kyoto, took their time to do so. Shimazu Yoshihiro didn’t see Ishida Mitsunari as a leader at all, and took umbrage with being gruffly ordered around. This caused Yoshihiro to sit on the battlefield and brood, waiting until after combat had been taking place for a while before committing his forces. Even more detrimental were the defections of several leading Western daimyo, most notably Kobayakawa Hideaki and Kikkawa Hiroie, whose combined 18,000 men falling on the flank of the Western force they were supposedly a part of (their actions encouraged by Tokugawa Ieyasu, of course) turned a close battle into a rout. (Edited note: this is not a blow-by-blow of tactical action at Sekigahara, which was obviously much more nuanced. I'm illustrating a point, that is all. Don't get bent out of shape because I simplify things.)

Had the western army had any unity of command, Japanese history would likely be very different. They had a number of tactical advantages (better terrain, more troops) that could have resulted in coalition victory, had there been any unity of command or unity of effort. Even a coalition can be very successful if the coalition members all strive towards the same goal. However, that didn’t happen, and the strongly-led Tokugawa forces took advantage of it.

Well, there you have it. Next time we’ll look at the Three S’s: Security, Surprise, and Simplicity. See you then!
