Well, this is very easy, first up; what's a fugitive?
A fugitive is a person that has escaped a place/or is in hiding;to avoid arrest/persecution.
So traveling by wagons,railroads,and walking makes sense. Except for one, slave ships, that makes no sense at all. Why would fugitive slaves travel on "slave ships?"
Germany invaded Poland unprompted, which started WWII.
India, Pakistan, North Africa.
Also it you didn't put this but also Syria.
Hope it helps! C;
