As it says.
I have finished roughing out the Case Blue map from the boardgame, which is 5 miles (8 klicks) per hex, but it doesn't go all the way to Kiev and Odessa.
OK, so, using the co-ordinates from the existing DC map, I tried ... and tried ... and tried ... and tried ... a whole day, in effect ... to get it to fit into the blank space at a scale of 8 klicks per hex.
I was prepared for the need to cut and fit a little bit ... but ... the locations from the DC map simply do *not* relate to those duplicated on the boardgame map in any way I can fathom.
The rest of the DC map *might* be 10 klicks per hex, or not (I haven't checked in detail yet, but I suspect not), despite the statement somewhere in the rulebook that the scale is such.
I am stuck.
I can't continue the map west, to Kiev, in any meaningful way. I can't continue the map east from Astrakhan, I suspect, for the same reason, likewise, I suspect I can't extend the map down past the mountains in the Caucasus or into the area NE of Stalingrad ... all areas not covered by the Boardgame map.
For the moment, I am fiddling ... in the west, with simply having rail lines and roads run from where the west edge of the Boardgame map ends to a notional west edge ... Kiev, Uman, Chernobyl, Odessa etc ... as this seems to be the best solution.
This will require some fiddling, as Kiev is an important VP city, though I guess I can place VP hexes at the entry to the rail/road corridors that lead through the black/neutral hexes to it ... though this is not my first choice.
I suspect that the same will have to be done with the Caucasus south of the mountains and the other areas mentioned.
What's worse, I have suspicions that the scale of the map is not consistent N-S and E-W, at least in the western area described, but possibly on the other areas as well ... I suspect the E-W scale is compressed and the N-S scale is extended, but am not sure.
After a wasted day, back to fiddling tomorrow ... probably just blacking in the areas left blank by the Boardgame map.
