Answer:
flashback of how the conflict between the two families date back to thier grandfathers' time.
Step-by-step explanation:
In the story "The Interlopers", the writer uses the flashback of how the conflict between the two families date back to thier grandfathers' time. It all started with a lawsuit which the dispossessed party never acknowledged and acquiesced.
The conflict is resolved when Ulrich von Gradwitz and Georg Znaeym decide to forgive and put everything behind them. When they were trapped under a fallen branch and were equally incapacitated, they both realize that it was wrong of them to remain enemies over a patch of land. The lines "there are better things in life than getting the better of a boundary dispute." helps us understand how Ulrich felt about the dispute.
The enmity and hatred between Ulrich von Gradwitz and Georg Znaeym over a land dispute which dated back three generations is the central conflict of the story.
The other conflict arises when they both decide to forgive one another and as they wait for their men to come and rescue them, wolves show up instead.
The last line in the story embarks an ironic ending. It ends the whole conflict which occurred earlier simply by mentioning the word "Wolves." It means that both Ulrich von Gradwitz and Georg Znaeym met a tragic ending when they finally resolved a generation long conflict.
