It probably won't help any game in progress, but you can plan ahead for it. The event, if it starts, will be in the same time frame every time. Here's the conditions and time frame:
Code: Select all
SelectFaction = USA
SelectRegion = $Richland_ND
StartEvent = evt_nam_USA_GreatSiouxUprising1862|1|2|evt_txt_USA_GreatSiouxUprising1862|Event-img_USA_GreatSiouxUprising1862|$Richland_ND|122
Conditions
MinDate = 1862/07/17
MaxDate = 1863/01/01
Probability = 50
By then as the Union you should be able to produce some extra cavalry units, which you'll need for any chance to catch them. I can't remember what leaders on the Union side have Indian fighter as an attribute, that are also available by July 1862. McCook has it, but he's kind of weak sauce as a cavalry leader. Good to have him leading stationary infantry in that area, though. So far as I can tell, the event doesn't have a conditional command for unit spawn location. Even if the Indian units don't spawn at the same time every time, they will spawn in the same place every time the event fires. You could plant units in and around those regions. That's gaming the system a little, but the only alternative to giving them a chance to avoid the power play would be to rewrite the event.
It's not the presence of Indians in the area or if you've defeated any of them, it's the presence of Union troops, so it's a pretty easy event to counter anyway.
