Reinforcments

[MoKus]

If you have 15 or less units in the field and you click to call reinforcements, they will pop up immediately on the unit list at the bottom of the screen. This way you an check if you'll get something or not. Units literally come out of the map and there is a margin where you can't command units until they get deeper into the map. Placing assembly flag close to the edge of the map is a good strategy to get control of a unit immediately after it leaves that margin zone.

I see. But nothing happen when I click on reinforcement button!

First, are you sure you have more than 16 units in the province you start a battle (not counting artillery)?
2nd, before you call for reinforcement, make sure at least one entire unit (to the last men) left battlefield. If you're not sure, count units' icons at the bottom of the screen. If less than 16, you're good to go.
When all conditions are met the reinforcement button will be displayed in color. Otherwise, it'll be grayed out.
That's all. If it doesn't work, I don't know how to help you.

Thanks for reply. It seems that all conditions for reinforcement are met but I cannot reinforce when I click the button. So something is wrong. Anyway, I resolve such a battle automatically.

Your assembly point may be far from the edge of the map, so the reinforcement may take a longish time to get there. If it the assembly point is in the woods or the way to it goes through the woods you may fail to detect it. But as Stazi said, look for the reinforcement unit icon at the bottom of the screen.

No new icon appears when I click on reinforcement button. That is sad. :(

Then the battle roster of 16 units must be full. If it isn't, I have no idea what it can be.

In the first post MoKus made he ( she ? ) , stated the pointer was red when the flag was set. This seems odd as a red pointer usually specifies that the pointer is outside of the battles "playing zone". Has the flag been set "Off Map"?! If so, perhaps this is why the unit fails to arrive...
