The dastadrly giants have assaulted one of my fortress with out ever declearing war.
They shall fall against the mighty longbows and nature+air spells of Man!!!
Btw, is maggots(the spell) good against Ermor undead?
Maggots is VERY useful against the undead hordes. Combine that with a good line of priestly types, and you'll have an effective force to use against the undead. Oh yeah, make sure you have some chaff units too. Militia or something.
