Thanks for clarifying your question. I think our answer still applies, though. If you move into a Ford as the first hex of a Gain Ground/Pursuit movement, you must stop. The way I read the rule for Pursuits in Fords is, if you are already in a Ford and your opponent is killed or Retreats, you are entitled to move OUT of the Ford to Gain Ground/Pursuit. I don't recall anything that would indicate you could ride straight through a Ford (from one side to the other) in one Pursuit movement.
Good question, though.
That would be my take on it also.
