moving into or out of rough.

I am sure this has been asked before, but I cant find it in the search, so here goes...

(concerning light horse, or any mounted for that matter, limited to 200 paces in the rough)

A stand of light horse moves 200 paces then encounters rough:

can they:

A: move 200 more paces into the rough, since they are limited to 200 paces in the rough and have 300 paces left when they encounter it?

B: move no farther, since they already moved 200 paces?

Thanks all,
John

The answer is B.

If part of the move is in bad going, the whole move cannot exceed the bad going movement allowance.

So a LH can move 199 paces in good going and 1 pace in bad going, but not 199 paces in good going and 2 in bad going nor 200 paces in good going and 1 pace in bad going.
