Referring to an exchange on the previous page, I know this is an elven support thread but my assertion about Andraste and the location of the Valarian Fields is based off information given in the first few pages of World of Thedas 2, where it is obvious that she never got further north than Nevarra. After the battle of the Valarian Fields it has the following to say:
"The farther into the Imperium Andraste pressed, the more resistance she encountered. Her army was running out of territories eager to accept liberation. The closer they came to the heart of the empire, the more they faced the enemy on home ground."
"If Tevinter found its full strength and its people were rallied against this heretic, Andraste, the Alamarri would be faced with a reversal of their success."
So it clearly says that after the Valarian Fields they were not yet in the heart of the Imperium, but the current location of the Valarian Fields is right in front of Minrathous. Also the Chantry maintain that the victory had been achieved against all the power that the Imperium could muster, which would make sense in front of the gates of Minrathous but the reality was it was strongest resistance of the outlying territories that they had vanquished, not the full might of the Imperium. I also would again point to the fact that if the victory had been achieved outside Minrathous, then the last thing you would do is retreat hundreds of miles back down south to Nevarra and allow your enemy the opportunity to recover its full strength.
At her execution it says: "The gathered crowd were not citizens of the borders who had felt the sting of the Alamarri, so they held no burning hatred for Our Lady."
Again, if the battle of Valarian Fields had been fought in front of Minrathous, then they had felt the sting of the Alamarri. The Chant also maintains that the combined forces of the Alamarri and the Imperium witnessed her death. Not so, according to this history. Her armies were still in the south. These citizens were people who had suffered nothing in the war and thus were of a mind to feel sympathy for a woman who seemed anything but a barbarian warlord.
