4. When it was discovered, by the inspector general, that Captain Holmes was pressuring Prewitt into fighting, what did the commanding officer do, as punishment to Holmes?
From Quiz "From Here to Eternity" 
Answer: Allowed him to resign for the good of the army
The commanding general considered convening a court martial, but one of the inspectors general offered that if the commander so deemed, he could allow Holmes to resign for the good of the army. The commander agreed and said that the sooner that Holmes was out of the army, the better for all of them and the better for the army. What was interesting here, about the movie, was that the commanding officer allowed Captain Holmes to resign while in the book he was promoted for his actions. The U.S. Army wouldn't cooperate with the making of the movie unless this part was changed, to present a more positive image of the army.
