A mission like this might be tried again, after all, and why let the other side know anything about how it had happened?

"Either side, though at the present I know more about the past than the future."

Both sides know that eventually it will come to a fight.

This was battle to death, and both sides knew it.

And the other side knows the ground better than we do.

And what the older side of man knows is called silent knowledge.

But people did not mind writing about them when both sides knew that they had been broken.

There's never been a time when one side knew so much about its enemy.

Now, the peace effort is seven years old, and the two sides know each other well.
