The scenario based quests like these tend to show a cinematic at the end to lets players know they have completed that portion of the quest and can return to the world map.
In this particular quest, when you return to your ally he should tell you to defeat the orcs pursuing you, after which there is a cinematic scene where he tells you the quest is over.
If that is not happening, then a bug may have occurred preventing it.
We will investigate and if we can find a bug we will fix it.
I'd recommend taking as large an army as you can into every quest, as some of them can be quite tough.
