Yeah, that's pretty much everything I could find online, too, and unfortunately those descriptions provide more questions than answers. NK's description is gibberish, and Tome of Treasures mentions things that just don't seem to be accurate - a "map board sheet" (don't know what that means), 7 paper counter sheets (I don't believe there are any separate counter sheets) and 8 maps (s/b 7, I think).
Based on the text of the rulebook, there should be 7 maps - A1, A2,
B1,
B2,
C1,
C2 and the Hydaspes Strategic Maneuver board. Included on a couple of those maps are the additional counters for the expansion. So that's it - 7 maps (including counters) and the 8 page rulebook. That jives with the picture of the components on bgg, with the exception of what appears to be an extra copy of one of the maps in the bgg picture. Anyone?
