What are three stories told in Chapter 7?

Three stories told in Chapter Seven are:

1)The story's narrator, Tim, relates about Bob Kiley/Rat writing to Curt Lemon's sister after Curt's death.

In this story, Tim tells us about Rat writing to Curt Lemon's sister. In his letter, Rat writes copiously about the heroic battlefield exploits of his late colleague, and he praises Curt for his nobility, unselfishness, and heroism. Apparently, Rat also tells Curt's sister that he had a close personal connection with her brother when he was alive; he maintains that he will look her up when the war is over. However, Rat supposedly never receives a reply from the young lady.

2)The story Mitchell Sanders tells about the strange music and sounds the soldiers hear in the Vietnamese jungle while out on a mission.

In this story, Mitchell Sanders tells about a six-man patrol on a reconnaissance mission up in the mountains. The group's task is to listen for enemy movements; however, they are instead treated to an eerie symphony of strange, instrumental music which seems to come out of nowhere.

According to Sanders, the symphonic music is blended in with the sounds of disembodied voices, Buddhist chanting, and orchestral singing. The soldiers become so paralyzed with fear that they order massive firepower against the unseen enemy. When the colonel demands to know how the patrol can justify their actions, the team is mute. They say nothing, because there are apparently certain stories that a soldier never tells.

3)The story Tim relates about Rat Kiley torturing a baby water buffalo after the death of Curt Lemon.

In this story, Tim tells how the platoon comes across a baby water buffalo after Curt Lemon's death. Initially, Rat offers the baby buffalo some pork and beans. When the animal refuses Rat's offer of food, the soldier picks up his rifle and begins to shoot at the baby buffalo. He shoots at different parts of the animal until the baby buffalo is too weak to stand.

Rat does not kill the water buffalo immediately; however, his torture of the defenseless animal is cruel and senseless. He continues shooting away chunks of flesh from the animal until the animal is barely alive. Then, without ceremony, Rat and his fellow soldiers throw the hapless animal down the village well.
