Quick report:
Using the 1.10-beta3, also
--Passive Posture
--Forced Marches
--Evade Combat Order
--Gray's forced Fair Weather files
--All generals always Activated
--Historical Attrition
and testing
--the Gettysburg 1863 scenario (using Bigus' test scenario)
--the Kentucky 1862 scenario (again using Bigus' test scenario)
--the Trans Mississippi 1861 scenario
I am pleased to report that the various corps, commands, and headquarters are all able to achieve historical rates of march. Yay!
Moreover, even with the Forced Marches (but in Fair Weather), and notably Lyon's 25% Command Penalty, all commands and forces arrive at their historical destinations in good shape for battle, with cohesion loss in the 10-20% range, and very little if any attrition. Yippee!
Of course, these are under ideal conditions, and don't reflect actual game play. But it's very nice to know that the latest beta patch settings, with perhaps a bit of luck thrown in, allow for campaigning pretty close to history. Hooray!
I can't comment yet on game play or game balance issues, or how this all impacts the AI, but so far it's all looking really good...
