AllCampaignsRemastered - Updated mod for all Campaigns

I need to check, but the idea is that they can be given the same route as the first attack of Agrail on the castle.

I don't know if it's possible to gather such an army through normal means so that the three heroes appearing to attack the city would just stand still. Maybe there's nothing to be done here. They appear quite quickly. I remember when I was playing, I didn't have such an army, and they attacked.
