Here's a breakdown of the key locations:
* The village of "Upper Coombe" in England: This is where the story begins, where the Peaceful brothers grew up.
* The "trenches" in France: The majority of the novel takes place in the muddy, dangerous trenches of the Western Front.
* "No Man's Land": The perilous territory between the enemy lines, which is described as desolate and dangerous.
The novel also touches on other locations like the training camps in England and the hospital where Private Peaceful is eventually treated.
