Cambridge Dictionary gives the definition of "fetch up" as "to arrive somewhere, especially without intending to" (Cambridge Dictionary). I'm stuck on the use of "against" with "fetched up". Does "against" mean "in the background"? If that's the case, what do you think about the substitution of "fetched up at the back of the town's general store"? Example: Elizabeth crossed the expanse of open space as indifferently as she could, fighting the desire to run, feeling very relieved indeed when she fetched up against the back of the town’s general store. Source: Timepiece Heather, Albano Background: During the Battle of Waterloo, Elizabeth's companions were taken away by British soldiers and locked up in an inn they had taken over in a small town in the neighborhood of Waterloo. Disguised as a French boy, Elizabeth came to the town after a long walk through Sonian Forest. Contrary to her expectations, the town was eerily empty. She suspected that the inhabitants either fled from the war or were shut up behind barricade doors. Still, she couldn't shake off the feeling of eyes watching her, so she had to walk as indifferently as possible.
