The attain the strategic position the Huns so recently conceded. Across the river to the west, they see that the Elves there, who were barraging the Huns with arrows (there are lots of Elven arrows lying around up here) have realized that their services are no longer needed. They are heading south.
It is hard to spot a specific adversary from a distance, but from up here they have a good view of what is going on.
Cleverly, we use the same map as before, but with the numbers having new meanings:
The party is currently located at position 3.
The Hun position on the hill at 4 fell to Brannoc, some Elven archers, and a cavalry assault. Just south, the main attack of the Huns is proceeding- from here the party can see that it is a massive clash of arms.
The good news is, with their taking of the bluff, and Brannoc's victory at the hill, the way looks clear- if the party follows the river due south, it looks like they can reach the battle with no interference.
