I talked with the major and learned that when it should start and our cars should be loaded we would drive them back along the screened road and up to the main road along the ridge where there would be a post and other cars to clear them. What effect does the style of this long sentence achieve?
The long-winded rant paints an image of a narrator who is less than stable.
The style reflects the mundane actions and events of daily life in a war zone.
The choice of simple words adds realism by mimicking the way people speak in real life.
The uninterrupted action mirrors how the orders will be carried out when the time comes.

The major was a little man with upturned mustaches. he had been in the war in libya and wore two wound-stripes. he said that if the thing went well he would see that i was decorated. i said i hoped it would go well but that he was too kind. i asked him if there was a big dugout where the drivers could stay and he sent a soldier to show me. i went with him and found the dugout, which was very good. the drivers were with it and i left them there. what effect does hemingway’s limited use of adjectives have? it slows down the narration by interrupting the action. it makes the few descriptive words he does use more vivid and forceful. it makes the narrator seem powerless and insincere. it prevents the readers from filling in the details with their own experiences.
