Battle of Hitotori Bridge (Hitotoribashi)

Hello,

I am an author of a miniature wargames ruleset called Killer Katanas
and I am finishing up on writing a second edition to the rules. I am
going back and relooking at my information to ensure accuracy.

With regards to The Battle of Hitotori Bridge between the Date and
Hatakeyama, I am unable to find a map scale or any references to
distances in the sources I have. When I made a scenario for this a
couple years ago I went by a painting and an "estimated guess" on the
distances. I'd like to be accurate this time.

If anyone could point out the distances between any of the following
places I can use that as a guide.

Places in the battle:

Town of Arai
Takakura Castle
Setogawa mansion
Motomiya Castle
Mount Daimyokura
Hitotori Bridge
Mount Kannondo

Thanks,

Brian
