How does a private school summer and war effect the events in A Separate Peace?

The disruption caused by World War II creates tension and fear at Devon School, affecting the characters' relationships and ultimately leading to the tragic incident between Gene and Finny. During the summer session, the students are left to grApple with their own insecurities and fears, leading to personal conflicts that intensify when faced with the larger backdrop of global conflict. The war serves as a metaphor for the inner battles and struggles that the characters face within themselves and with each other.
