They march down the brass road, others make camp to see how their peers will fare. The pikemen vanguard has stalled after their leader was incapacitated, they mill outside the courtyard awaiting reinforcements. Reinforcements are galloping into the brass palisade with increasing regularity, the fortifications still hold, and they have not yet breached the axe blades.
The soldiers on the north face are of less concern, far away from most of the fighting. Given their large number of archers and crossbowmen, not a high priority target. Still, those axemen look to be in prime location to drop the sky.
The eastern defences have seen considerably more success, many humans or their mounts were captured and the drawbridge was sealed in time. I am in the interest of protecting Forgotten Beast habitats, for they are endangered species. Some are just of a nature too deadly for me to wish upon the surface.
The mosquito riders have been repelled, a few lofty mosquitoes remain vomiting in the sky but they will eventually fall. Over a dozen or so humans and their loyal steeds have been shot and killed, their corpses spilling blood into the magma below. All in all an insignificant amount of humans have died.
The eastern tunnel connects the northern territory with the southern; being an underground passage which cannot be defended from the Fortress, it was fitted with some nasty traps to discourage any attacking foes from taking up residence within. The traps did their job and though they allowed about 60 cavalrymen through before most of them ended up jammed, they must've injured a great deal many more horses, slowing down the human advance. One copper spike still works, and the northern squads should lose at least 3 more men to it before they completely own the tunnel.
Troops are still moving around back and forth as the Fort is alive with Dwarf feet and human screams.
The Marksdwarves are spread along the entire Fort to maximize coverage. The 2nd level battlements are covered in doors so that when a Marksdwarf has finished firing, is changing tower or is coming under too much fire they can pull back and the doors fasten shut blocking any arrows that might make it through a fortification. It also helps narrow fields of view drastically, so marksdwarves can reposition themselves to duel two dozen enemy archers whilst putting themselves at risk to only 3 or 5 enemies (most of the time). So far they've killed a few humans and war animals but just as before, not enough to make a noticeable difference. There is a silver lining in that Marksdwarves related to Feb Phrasecobalt have had something to cheer up about (or vent anger on) as a result of the siege.
