Just broke my first real siege.
While the gobbos had "sieged" once before, that sad attempt was just 14 Lashers and an Axegoblin leading them. Crushed without effort - did not even raise the bridge. They were quiet for a couple years after that. Then it came, in Pagegrips' sixth year, shortly after having been elevated to county. Over 100 Invaders (including mounts), approaching from all sides of the map. War Jabberers, Cave Crocs, Blind Cave Bears. Some elites including a Master Lasher. And the worse part - Giant Cave Swallows. There was even an Elite Bowman on one of the flying mounts. That has got to be cheating.
I went full melee this fort. Hunting was sparse and I didn't want to bother setting up an Archery range for training. Ooops. Two civilians got caught before they could make it back inside. Pagegrips' first casualties.
Out went my fortress defense - 4 Axe Lords, 3 each of Spearmasters, Hammer Lords and Swordmasters. My last squad of 4 more Axe Lords I held back behind the curtain wall to deal with any flyers that landed in the open courtyard. Across the bridge is an open paved road, 9 x 20. Here I stationed my warriors, but they did not stay still long.
I lucked out. The Elite Bowman just flapped around on his Giant Cave Swallow in place, well out of range of the action. 47 kills later, the Siege was broken and the invaders sent scattering. 4 Speargoblin stragglers on their big birds flapped around keeping me from inactivating the Civilian alert. Then I remembered my Captain of the Guard had a crossbow, so I called him up. He was too slow picking up his gear and the last of the Cave Swallows was bashed to bits before he could fire a single bolt. No injuries to the warriors.
53 total kills in exchange for 18 year old Bomrek Stokedlance, Tanner and 24 year old Mistem Cobaltdeaths, Blacksmith. They had been hauling stone from my quarry. Their deaths are because I didn't want to mess up my fortress design with a tunnel out to where I was collecting coal and limestone. I guess I should rethink my designs.
