When he stood up from the wall he saw he left a hole.
Was the wall fixable at all?
The wall was still standing, but there was just a big hole in it now.
You should let someone know what happened. Even though it wasn't you who did it, someone needs to know so the wall can be repaired.
It's in the past. Nothing to worry about.
As long as the wall has been fixed, then everything is fine since it wasn't your fault. Hopefully the person who made the hole apologized to whoever owned it. They shouldn't have been so careless as to damage something that isn't theirs.
