At first, you may be wondering about this law since it sounds paradoxical. But like how Aristotle explained the mean of the virtues in Nicomachean Ethics, this law is just a matter of being balanced.
First let's talk about the deficiency. Having no fortress or any sort of protection as a leader would expose you to danger as you will become very vulnerable especially in war. Try to imagine this: If you are the leader and you go ahead of your whole army, the chances of your army being defeated by the enemy is very high because it exposes you to danger . . . being in front, ahead of your army would mean you will lack defense and protection.
On the contrary, protecting yourself too much, as stated with this law, is as dangerous as being exposed in war. It may sound strange, but protecting yourself too much would eventually lead to isolation. Why isolation? In a fortress, sure your enemies would not be able to penetrate the walls of your fortress, but still you as a leader is vulnerable in three ways:
Weak spot #1: Isolation from the outside world
-Because you do not know what is happening outside, chances are that the enemies have a higher rate of making a surprise attack to you against your fortress. By lacking awareness about the outside world you cannot make proper plans in order to eliminate the enemy.
Weak spot #2: Traitorship
-The cliche 'never trust anyone" applies very well with this because you never know about the loyalty of your soldiers and army. Being such a demanding leader to guard your fortress will leave you vulnerable as your soldiers can fall into bribery caused by the enemy, thus telling to the enemy your whereabouts, eventually leading to your defeat, or worse, death.
Weak spot #3: Sickness & diseases
-Sure the best way of avoiding weak spot number 2 is not to tell your soldiers and allies about your whereabouts, but it is still a disadvantage since a fortress is an immobile place hence being vulnerable to plagues and diseases. No matter how hard you try to hide and not tell anyone your whereabouts, sickness can get the best of you as there are many possible outlets for diseases like water, food, dust, etc.
In the end, the most ideal way of saving yourself from enemies is to build a fortress where there is an open access to the outside world. Louis XIV's fortress is an ideal example since he is well protected by his palace and at the same time he has open access to the outside world, giving him more accuracy and flexibility in planning on how to fight against his opponents.
In addition to this, isolation is a deadly thing to human nature as it is natural for humans to be sociable and thus having a common desire to interact. The bad thing about building a fortress is that it also brings you more to isolation. Isolation is bad because without interaction from allies, it would be difficult to battle against the enemy.
No man has defeated an army on his own.
