Step 1: Recalling the Text:
The story highlights how self-interest can override strict wartime principles even among high-ranking officials.
Step 2: Explaining the General's Response:
Dependent on Dr. Sadao as his surgeon, the General quietly ignored the incident to keep Sadao available and willing to operate on him.
Final Answer:
Because the Chief General relied on Dr. Sadao's surgical skill for his own health, he chose practical self-interest over punishing Sadao for sheltering the American soldier, and let the matter pass unpunished.
