w/10 4716: 61 - 62
w/any cavalry: 65
w/any unit or w/1 4328: 58
4223: Train

Design Note.

Yes, I know Buford and his brigades weren't there on the third day, but I deliberately did not include rules for withdrawing units from the game. There was no good reason for the cavalry to withdraw: yes, they were tired, but so was the rest of the army ($*&-#! cavalry) - and the Union player is not likely to push them off voluntarily. A more generic rule allowing units to leave (probably through a FOW) could have led to some weird results.

Works Setup (if 20.0 is used)

Scenario III:

Union player gets 6 breastworks, which,' may be placed on or adjacent to any Ceme- i tery Hill hex (the Big Hill hexes contiguous with hex 3031), plus 2 breastworks with any unit from formations 1 or 2.

Scenario IV

same as Scenario III, plus trench markers in hexes 3226 and 3227.
