After crushing a winter siege I was expecting a short lull to allow for spring trading with elves and cleaning goblin corpses out of the tunnels.
No elves this year. Instead the spring event was another goblin siege. Smaller one though, only three infantry squads and one squad of trolls. A very uncoordinated assault on the two open access tunnels. And no archers - all melee troops.
First squad hits the north tunnel with the magma trap currently covered. They hit some traps, then some more weapon traps, and then the squad leader decides that it's time to retreat. To discover that there is now a nice dodge-me trap between the squad and the tunnel exit. The leader and the 2-3 goblins not currently bleeding out fall into the magma. Scratch one squad - and cover the magma back up.
Second squad is headed for the south tunnel and I figure I can pull the same stunt. But wait, what is that dwarf doing in the tunnel? It's a sword master going out to fight the squad by himself. (This tunnel and that squad seem to keep doing this.) I summon some reinforcements, but they won't get there for a little while. So we get Solon the Swordmaster verses a squad of goblins armed with axes and halberds led by a Pikemaster. I note that Solon has all his steel armor on, but is using a copper short sword while the goblins are using leather armor with metal (copper/iron) caps and shields. Advantage DWARF.
Solon exits the tunnel and the fight begins. He disarms a halberd goblin in the first exchange with a nice arm strike while three goblin attacks miss. Then he has a short duel with the goblin Pikemaster (they miss each other, get tangled together and go tumbling, get up, and Solon stabs him in the arm causing artery, tendon, and nerve damage.) Solon dodges or blocks four more attacks while wounding another goblin. Solon takes a moment to chop the Pikemaster in the head a few times and finish him.
At that point the goblins start running towards the map edge. And two axe dwarves turn up. The goblins are chased off the map while taking a few more casualties. So much for the second part of the attack.
About now the trolls start streaming into the north tunnel. A few fall in magma, and the rest go down weapon traps and some lever spikes.
The last squad arrives to find the magma covered and the spikes turned off*. They start getting through the grinder successfully** - to meet a dozen militia dwarves coming the other way. That finishes off the mace goblins and the siege. And a couple were cage trapped for the marksdwarves to practice on.
* - This doesn't indicate TIE fighters coming, but does indicate the imminent deployment of steel-armored dwarves to the area.
** - Investigation discovered some hatches not wired to the pressure pads. OOPS!
And the militia captain wounded in the last siege died of an infection. That the doctor apparently didn't discover the silver arrow still in the wound was annoying. The other wounded spear dwarf has returned to limited duty.
