In recent events, my fortress was being menaced by a Giant Hamster, along with a couple of Hamstermen/women. Unfortunately, one of my marksdwarfs had forgotten to pack her crossbow, and so engaged the giant hamster in melee combat... whilst holding her baby. Whilst they both put up a good fight (the baby got a couple of good hits in on the hamster's eyeballs), they were eventually defeated, with the mother's legs being bitten off and the baby dying of blood loss from a puncture wound.
Thankfully the rest of my dwarven army were able to kill off the giant hamster and hamsterpeople before anything else could happen.
In other news, children have started to overpopulate the fort, so I'm devising a sort of "training programme" for them, involving dumping them into a pit full of hostile mosquito men. Those who survive will actually be able to contribute to my fortress. The others might just be lucky enough to be resurrected and provide training dummies for future generations.
