General discussion about Heroes of Might and Magic II.

If there's an autosave, you can use a cheat to open it and see where the Sorceress is located before the turn begins. Besides logistics, boots, and transport spells (which, by the way, can also be obtained through a scroll or a pyramid, in addition to the guild), the speed of movement is also influenced by visiting special locations, such as a stable or an OASIS (a factor that is often overlooked). Theoretically (though I doubt it), the Sorceress could have been positioned with her Phoenixes before the turn began, and the rest of the army was brought to her.
