In A Separate Peace, what effect does the war have on Devon?

The war's effect on Devon is similar to its effect on the boys. When Gene returns to Devon after his break and after visiting Finny, he observes that some of the younger professors are gone--called up for the war.

Most importantly, Gene mentions that "peace had deserted Devon" (72). While this is partly a result of the war, it is also caused by Finny's absence and the brewing "war" within Gene.
