Thank you all for your comments, gentlemen.
In fact it now happened to me, this turn. I can promote Meade, but Phil Kearny will feel passed over. Actually Phil Kearny was one of the guys I had in mind when talking about non-promotable generals who I think should better be promotable. No doubt, had he lived, this chap would have gone far. There's a reason why I have him still in command of a corps (whereas Sumner was there simply by default). ("Had he lived" is a valid argument I think, as long as my opponent has ASJ in charge of an army. Only he was already an army commander ere his death at Shiloh, historically, so the promotion problem does not arise in the game.)
Question (I know I ought to know the answer, but seems I don't): If I choose not to promote Meade this time, will the offer come up again when he fulfills the conditions next time? Or won't he ever again come up for promotion? In that case, of course, damn Kearny and the 148 VP, Meade still gets his star.
