I'm voting he wanted his future son-in-law to be the great general after him, since he was already fascinated in the battles of old. This way, she could focus on being one of the best politicians to live in Ferelden.
I'm between the traditional mentality of Loghain and the Anora not being interested.
Anora is a smart and capable woman, which I think would be good qualities for a general (and other good qualities that a person like Loghain would see). But she doesn't seem interested in getting stronger physically or to learn how to fight (if she already doesn't know, that is, because I think she knows the basics).
As for myself, my understanding is, Loghain intentionally refrained from training Anora, because he didn't wish Cailan to be overshadowed on all departments. And Anora resented this decision.
It's a decision both emotional and practical. But it's not for Cailan. It's for Maric. Out of loyalty and affection for Maric. Loghain wanted Maric's only son had something to be proud of. Except for good-looking, Cailan doesn't have many redeeming qualities, and I doubt it takes Loghain long to be utterly disappointed with him. But he is Maric and Rowan's only child, the only thing in this world that could remind him of them, once they are gone.
There is also practical consideration. Cailan is a vain person, but also incompetent. Hubris and incompetence, that's a deadly combination. If Anora is too capable on all matters, it wouldn't take very long for Cailan to turn against her out of jealousy and insecurity (even if he doesn't, people like Eamon would encourage him). And if Anora is also a great warrior and enjoy popularity among soldiers like Loghain himself, then there could be only one result for such dispute. I doubt he could bear to see his own kid murder Maric's. (Of course you can mention Ostagar, but it would be very different between making the hard decision yourself or leave others, especially your kid to it.)
Besides, as long as he is alive, he would believe there is no reason for Anora to lead the army, even if Cailan eventually proves totally unfit. Maybe then he would still have time to train her before he dies.
So, in short, Loghain curtailed Anora's ablities and rendered her in a vulnerable position, all because his loyalty and affection for Maric. Loghain no doubt loves Anora, but he simply loves Maric more. He desperately wants to cling to anything left behind by Maric, even a very unsatisfying progeny like Cailan.
After Cailan's death, and especially witnessing what Howe has done, how Anora is completely defenseless in regard of a rogue warlord like Howe, Loghain must realize what a terrible position he put his daughter in. But then it's too late. Having to campaign against rebels constantly, he no longer has time to rectify this gigantic mistake.
I have not read the Stolen Throne, so all my knowledge of Loghain stems from Origins. If I were to guess at his motivations, I'd say that he didn't train her to fight because he wanted to believe that she would never have to. You only train someone to fight if you think that they will need it. Loghain fought to end Orlais occupation of Ferelden. You fight such a war so that future generations don't have to, to make sure that they can live free of oppression and war. Loghain has seen the horrors and war and I believe that he'd rather that his daughter didn't. I think not training her makes it easier for him to believe that she'll be safe from such things, or at the very least by not training her he can avoid thinking about the possibility.
Cauthrien destroys the "traditionalist" argument.
I don't remember learning this in-game, but from what I understand, there's dialogue indicating she is trained to fight.
Maybe you should add "I think he did" to the list?
I think it's probably to do with Rowan. Lines in The Calling indicate that he never got over Rowan and that he didn't like spending time with his wife and Anora. It could be that he didn't train her because he didn't want his daughter to become a warrior and remind him of Rowan and it could also be that he didn't want to spend time with her at all because she's not Rowan's daughter and so never really taught her anything.
^ I remember reading about the Loghain- Anora father-daughter relationship and thinking they were super cute. So I don't think that was the case.
There is no 'traditionalist' attitude in Ferelden which frowns on women being trained for combat.
^ Howe clearly remarks about the noble woman "all grown up and still playing the man". Her mother also says something similar about how the guests have seen us sweating and hitting soldiers while training.
It is allowed, evidently. But it is not seen very well. If you were a boy you wouldn't be questioned like a woman would.
The "woman should not be training, but chasing boys to marry" sounds really sexist to me. There's obviously some old mentality there from a lot of characters.
What do you think?
