Heolstor takes some time to meet with the other leaders and get a handle on things. They quickly figure out, it's not so much the town center the Huns will defend, it's the north eastern wedge. Heolstor sends forces to cover the bridge and the main gatehouse, and the light cavalry heads out outside, to interdict anyone trying to move across the bridge, while others begin securing the route to the main gate and bridge from the inside. The first reports show that the main gatehouse is, like the south gatehouse, a stronghold.
And the Orcs within are not going to be taken by surprise.
A few riders have circled the town to the west. The report comes back that they cannot see another gate. There is a place where there seems to have been a gate once, but it s blocked in. The Huns may have a secret escape route, but no other large gate.
Other scouts find out that the least protected area of Tullum is actually the cluttered, dirty peasant quarter occupying most of the west side, the largest of Tullum's quarters. The Huns apparently feel it is beneath their dignity to worry about it. But it would not be easy to move through, most of it is a maze of little congested alleys between ramshackle little homes.
The Elves are arriving, and they are outside the south gate.
The troops have pushed a hay-bale filled wagon in front of the stone house the Huns hold on the opposite side of the south gate plaza. This blocks arrows from the windows, and the south gate plaza is safe, but Gerolf recommends troops storm the place, or do something, because he doesn't like the idea of leaving a stronghold of Orcs behind when they move further in.

And the immediate area around the gatehouse:
