Impassable vs. impassible

Something that is impassable is impossible to pass, cross, or overcome. Impassible originally had a different definition—namely, not subject to suffering, pain, or harm—but today it is rarely used in that sense and is commonly used in place of impassable.

    i’m struggling to understand the original definition of impassible — can someone think of an example sentence? might it be something like ‘when the fortress was invaded the horses in the stables were impassible’? that sounds kindof weird?
