So now let’s get to the outline of Sun Tzu’s The Art of War.
This is going to be a simplified overview, outlining the 13 chapters and some basic principles
that we can learn from them, applying them to a variety of modern fields.
Let’s start with a quick rundown of the author.
Born Sun Wu around 540 BC.
I say around because a lot of Sun’s history is disagreed on.
Where he was born is even unclear.
There are conflicting and unreliable stories here, some even questioning if Sun Wu was
one person or an amalgamation of other notable men.
You can understand after 2,500 years if things get lost in translation.
He eventually rose up to become a general, earning the title of Sun Tzu, meaning Master
Sun, and writing the military guide that we’re discussing here today.
Regardless what’s true and real about the man known as Sun Tzu, the book that we’re
talking about is a concrete thing, a real thing.
It’s been translated many times and we’ll use the chapter headings from the 1910 translation
from Lionel Giles, a curator at the British Museum.
He took aim at previous English translations, saying that omissions were frequent and passages
were skipped because they were difficult to translate.
So let’s dive into chapter one: Laying Plans.
War is not a pleasant thing, argues Sun Tzu.
It’s serious. It's about survival.
You should think carefully before engaging.
If a general thinks closely about which side is stronger, has more discipline, which is
better trained and organized, than they can work out who will and who will lose.
If you look at the two sides and your enemy has many advantages and many strengths, the
wise move is to avoid conflict.
You can predict your loss and therefore avoid the loss.
One major factor in this determination is something called the Way, which is about the
moral stance of a side.
If the general is righteous and virtuous, he will likely have more command over his men.
Sun Tzu also flips his idea of strategizing that you should learn all you can about your
opponent, while making your opponent blind to your true state.
If they can’t gauge your strengths and weaknesses, it’s harder for them to succeed in battle.
This whole chapter is planning and preparation.
Chapter two is called Waging War.
This gets into some incredible detail that seems specific but has massive repercussions.
He outlines how many horses you should bring, how many troops should follow a general.
But what he’s saying is that money and human lives are not be used recklessly, they are
both finite resources.
If you wage a huge war, it can be taxing on an army.
They become exhausted, their supplies dwindle.
The key takeaway from this chapter is to strike quickly.
Your army should never need reinforcements or new provisions.
Strike quickly, so that the impact on your treasury will be slight.
Many losses at war are due to the attrition of people and supplies.
This chapter also talks about using the resources of your enemy.
Do not destroy supplies you can use, do not burn food that you can eat, and don’t kill
soldiers that can either give you information or join your own ranks.
This chapter is all about resources and using them wisely, not recklessly.
We move onto chapter three Attack by Stratagem.
This begins by reinforcing the idea of not destroying everything in war.
A city razed to the ground is of little use to, where it’s more beneficial to strategically
destroy them politically and leave the city and people intact.
He then gives some very direct strategies for how to attack based on your army versus another's.
If your forces outnumber the enemy largely, surround them completely.
If it’s five to one, attack them.
At two to one, divide the enemy and fight them that way.
If it’s even, fight them head-on, one on one.
If they outnumber you, hide.
If they outnumber you greatly, escape.
Foolishly fighting a losing battle will end horribly.
Sun Tzu then outlines five essentials to consider in your strategy here.
You must know when to fight and when not to, referencing the strategies I just talked about.
You must know how to deploy an army and where.
You must have united officers and men serving.
You must be prepared for any surprise.
And lastly, you need a general who can make his own decisions without political leaders
interfering without expertise.
None of them essentials talk about more men or more technology.
It’s about strategy and preparation.
He said paraphrased, “If you know the enemy and know yourself, you need not fear the result
of a hundred battles.
If you know yourself but not the enemy, for every victory gained you will also suffer a defeat.
If you know neither the enemy nor yourself, you will succumb in every battle.”
Chapter four is Tactical Dispositions.
This chapter is all about when to advance and force a battle.
To attack, you become vulnerable, but to defend is to become invulnerable.
The idea of ying and yang is played into here, with an ebb and flow based on your choice
to advance or not.
Sun Tzu even evokes imagery of moving under the Earth when defending and striking from
the heavens when attacking.
There’s also the focus on a quick and decisive attack, that some fights may never take place
on a battlefield, if fought correctly.
A skillful general seeks victory, not battle.
A terrible general seeks battle first.
Chapter five is Use of Energy.
Managing a massive army is just as managing a small one, but Sun Tzu focuses on dividing
them up and knowing each of their purposes.
You must push and pull these units to effectively attack.
If you see a weak point, pushing a unit into that point may collapse the army.
If you pull your forces back and bait the enemy, you can engulf them as they arrive.
Sun Tzu compares this to rivers and streams, ebbing and flowing.
Every directive to your army is either a direct action or an indirect, there’s really nothing
else, he affirms.
How you use your army connects to chapter six, Weak Points and Strong, or strengths
and weaknesses.
In your preparation, you want all the circumstances to favor you and your army.
If you arrive to battle first, your men rest and wait, defending their ground.
If you arrive to battle second, your troops are already tired from marching and now must fight.
Force your opponent into weakness.
A strong army must eat, so how can you starve them?
An army that is steadfast and unmoveable, how can you force their hand to make them adjust?
The defender must defend all lines, making every part weaker, so the general of an army
must make a point to attack only a few points with all their might.
All of this relies on the plan being secret, otherwise the defender would defend only those points.
Secrecy is key.
Chapter seven focuses on Maneuvering.
This is the strategy of making commands and orders of a physical army.
If you force your army to march for 30 miles, you’ll lose men for all sorts of reasons.
There’s a balance between pushing them to gain an advantage, and then pushing them too far.
Early I mentioned getting to the battle first.
That’s useful, if your entire army arrives at all.
He says commanding a force that listens and obeys is one thing, whereas trying to command
a force that’s disobedient can bring you to ruin.
There’s a story about Sun Tzu where he’s challenged to train an army out of concubines,
seemingly impossible.
He gives an order, they laugh and carry on.
He then executed two of the King’s favorite concubines.
Now, everyone listened and maneuvered exactly as directed.
In this chapter he’s saying that a force must listen to the general, because it’s
chaos if they don’t.
He also talks about how to give these orders here.
If it’s night time, use torches.
If you manage many, use drums when your voice can’t carry.
This speaks to communicating different in different circumstances.
Sun Tzu even brings up which troops you should focus on.
The men who are sharpest need very little help, but the slow and homesick, the General
can greatly affect and improve morale.
Find weaknesses in your own men, in your structure, in your processes, and try to avoid them or
strengthen them before you arrive to battle.
Chapter eight is Variation of Tactics.
Circumstances sometimes call for different tactics and different choices.
There are cities you should not attack, there are roads you should not take.
In your preparation, you see that some choices will be catastrophic.
These tactics all come from the general and there’s five major ways that a general can
fail when deciding tactics.
Being reckless and impatient leads to destruction.
Cowardice and fear leads to eventual capture.
A hasty temper means one can be baited and provoked.
A high standard of honor means one might be susceptible and sensitive to shame.
Lastly, an excessive compassion for the troops might make a general second guess his decisions
and worry about them, as opposed to focusing on victory alone.
Sun Tzu claims that whenever an army is defeated or a leader slain, one of these five faults
is to blame.
Chapter nine is about The Army on the March.
He gives some very specific instructions here, including to camp in high places facing the
sun, to always have the high ground when facing your opponent but don’t expend your energy
marching uphill needlessly.
When fighting near a stream or river, let the enemy try to advance all the way through
and expend their energy, as opposed to rushing to meet them.
How your opponent rushes to face you tells you of their situation.
If they wait for you to approach, they have strong defenses and might see some obstacles
for you to overcome.
If they’re approaching, look for signs, such as trees moving and animals running scared.
High dust in the distance might mean horses, while low dust might mean walking troops.
Also be aware that you’re giving off these signals as well, as your army travels.
Classification of Terrain is chapter ten and literally lays out for the general how to
read the terrain and the benefits of fighting in each.
Accessible terrain is terrain that anyone can traverse easily.
The advantage goes to the general who can secure a high ground before the opponent arrives
and has sufficient supplies to last throughout.
Entangling ground means it’s easy to move forward, to secure new land, but it’s difficult
to backtrack or retreat.
Make sure your enemy is vulnerable before moving forward.
In deadlock terrain, or temporizing as the direct translation, there is no advantage
for either side.
If you can back out and make the enemy advance into this terrain, you should be able to strike
with advantage.
Enclosed terrain is usually a narrow passage with very little options.
If you get to this location first, you can block it or ambush.
If the enemy garrisons this space, only advance if you’re confident that it’s weakly protected.
If you come upon terrain that is rocky and has high peaks and low valleys, you should
secure the high peaks first.
If your enemy has the high ground, retreat and force them to leave these advantages if
they wish to pursue.
In this same chapter, Sun Tzu outlines some non-natural factors that a General must look
out for, that can cause harm to the army.
If the enemy outnumbers you ten to one, your army will fly in fear or retreat.
When the army troops are strong-willed and determined, yet the officers incompetent,
the result will be the troops not listening to the officers.
If it’s reversed, with strong competent officers and weak soldiers, the result is
decay and defection.
If the officers act without command from the General, the army will collapse.
Disorganization occurs when the General can’t articulate his plans so the army doesn’t
move as one.
When the General chooses to pit a weak army or a weak detachment against a much stronger
one, the only option is retreat or defeat.
The best Generals know the terrain, know their army, and know which difficulties they will face.
Here are the keys to success as outlined by Sun Tzu.
If a ruler says not to fight, but a competent General sees that victory is clear, they should fight.
The same is true if a ruler says to fight but defeat is certain, then do not fight.
A good general makes decisions without seeking fame or fearing blame.
A general cannot be confident if any factor of the battle is unsure.
If the terrain is unclear, victory is not certain.
If he does not know his soldiers, victory is not certain.
He is confident with his movements, as any doubt can sow doubt in the troops.
Chapter eleven dives into scenarios, called the Nine Situations.
These are situations that an army might find themselves in, not entirely reliant on the
physical ground they’re on.
Dispersive ground is when a General fights in his own homeland, on familiar ground.
You may have the advantage, but damage may be done to your own supplies and property,
so be wary.
Facile ground is when you’ve broken into enemy territory, so you should not slow down.
You don’t have the advantage but you haven’t gained much, so you must fight on.
Contentious ground is when either side can gain a great advantage by taking a particular
place, so move forward but don’t engage too aggressively until you have a clear advantage,
otherwise you might lose a key victory.
Open ground means that both armies have complete freedom, therefore it’s wise to not try
to stop the enemy’s movement, you have no terrain to support you.
There’s intersecting ground, where multiple states or constituents have interest, this
is your chance to make allies and not enemies.
When you’re on heavy ground, it means you’ve made much progress and there are entire cities
behind you, this is your chance to plunder and restock with so many resources available to you.
You may run into intractable ground, or difficult ground, which means it is full of marshes
and forests and hard to get through terrain, in this instance you must keep moving to get
out of that disadvantage.
You must also look out for enclosed or hemmed in ground, which is twisty and narrow and
leaves you vulnerable.
In these instances, continuously keep an eye open and remain vigilant.
Lastly we have desperate ground, or some call it death ground, where you are merely trying
to survive and you must fight with every ounce of your being.
If your opponent is striking so powerfully, it also means they are vulnerable there is
still a chance for success here.
Chapter twelve The Attack by Fire focuses on weapons of war, though weapons at the time
were very different.
He brings up five ways to use fire: Burning enemy soldiers, destroying supplies, destroying
their supplies that are still in transit, destroy their weapons and ammo, and destroying
lines of communication and causing chaos.
You should always have your weapons ready and available for use at a brief notice, as
long as the weather is hot and dry, ideal for fire to spread.
Sun Tzu then talks about when the fire breaks out, there’s ways to adapt to it.
If you attack with fire, follow immediately with an physical attack to capitalize.
If you attack and there’s no response from the opposing army, it may mean that something
isn’t as it seems.
They may be baiting you, they may have been prepared, so wait and watch as the fire continues to spread.
When the fire reaches is greatest peak is when you should attack, do not wait for it
to go out.
If you can start a fire from inside the camp, that’s beneficial as opposed to trying to
attack from outside.
Always be upwind when starting fires and remember that nighttime fires likely die quicker than
daytime fires.
If fire seems too risky or destructive, using water as a weapon, if the terrain allows,
can also be a clever move.
Though here he’s saying fire, I think these ideas can be transferred to other modern machines
of war as well.
Chapter thirteen brings up another type of weapon, the Use of Spies.
Early on in these tips, Sun Tzu brought up the idea of preparation and knowing your enemy.
That’s not always easy, so in this chapter he emphasizes using men who know the enemy
and sorts them into five types.
Local spies live in the opposing nation or group, internal spies are actually within
the enemy structure or government, and double agents are spies sent to find you that you
have turned to your cause instead.
There is a thing called doomed spies (or dead spies in some translations) that exist to
pass on false information to your enemy.
So they might make your enemy think you are starving or taking a route that you’re not
actually taking.
And lastly we have live spies, who infiltrate and then return to your ranks with information
though aren’t from that camp.
Sun Tzu says that these intelligence gatherers should be the best paid and best treated,
as this wisdom is key to winning a victory, especially a bloodless one.
Every move that a General makes is based on this intelligence.
So now we’ve covered the thirteen chapters and what Sun Tzu had to say about the art of war.
There’s many ways that these tactics can be used today, especially in business circles.
How you run a business and compete with other businesses is an obvious parallel.
Intelligence is key, preparation can defeat seemingly insurmountable odds, and knowing
which battles to fight.
Down in the comments, I want you to share some ways that you’ve seen some of these
tactics play out in your life, either in work, in your personal life, or somewhere else.
Hopefully you found this interesting, I hope it helped you get a grasp on this!
