"And what brought me here? Why should I be here?"
"You came here voluntarily, while you were in good health, no doubt, and while your mind acted perfectly."
"But why should I have come?"
"Because your regiment was ordered to come."
"And why should there be an army?"
"Because your country was invaded. You volunteered to defend your country, and your regiment was ordered here."
"Country invaded? Volunteered?"
"Yes."
"Then we are at war?"
"Yes."
