Another example of foreshadowing in the story is when the falling beech tree pins both Georg and Ulrich down. When the beech tree is felled by the tempestuous storm, both men find their limbs tightly pinioned down by the vast branches. Since weather is a natural phenomenon neither man can control, the incident foreshadows Ulrich and Georg's final ambiguous fate at the hands of wolves (another element of the wild that neither man can control).
Later in the story, however, both men make peace with each other. Ulrich is the first to reach out to Georg. He offers him a drink from his flask of wine and asserts that they've been fools to let a boundary dispute divide them. Ulrich offers to let bygones be bygones if Georg will agree. For his part, Georg agrees with his old enemy, even though no "one living can remember seeing a Znaeym and a von Gradwitz talking to one another in friendship." In a stunning development, both men make a truce of peace with each other. At this point in the story, we imagine that things may end nicely after all. However, Saki decides to reiterate that things may not end well after all.
So, he uses the weather to foreshadow the eventual catastrophe that will afflict the men at the end of the story. Notice that the men have made peace, but the volatile weather has still not ebbed in its entirety.
For a space both men were silent, turning over in their minds the wonderful changes that this dramatic reconciliation would bring about. In the cold, gloomy forest, with the wind tearing in fitful gusts through the naked branches and whistling round the tree-trunks, they lay and waited for the help that would now bring release and succor to both parties.
In the story, Saki uses foreshadowing and other literary devices to reinforce a major theme: generational conflicts are futile and often result in senseless violence. Similar to the generational conflicts in works like Romeo and Juliet, The Interlopers reinforce the tragedy of inherited generational feuds. In Saki's story, we are stunned by the ironic ending; despite the peace agreement between Ulrich and Georg, nature gives them the original desires of their hearts. Thus, instead of celebrating each other's rescue, both will presumably face an ugly death together.
