Evacuate. Especially if civilian casualties are a high risk. 24 hours should be enough time to evacuate a small holding. Rig what's left to "self destruct" with Explosive Runes and let the enemy have fun. Unless the party is sufficiently high-enough level to make this a non-challenge.Eh, let's say that they're genocidal members of the anti-human Bear Cult sect of giantkind. If they take your stronghold they'll kill all the humans they can find and tear up your infrastructure. Best-case, even if you evacuate and then reoccupy after the giants have left, you're looking at losing a couple hundred children and old folks (some to the giants and some to sickness and disease during the evacuation), about 25,000 gp worth of infrastructure, and 50-100% of the 5000 gp per month you've been raking in from your manufactories in the stronghold.
The orcs have bows but normal orc stats, so they're not particularly skilled at using the bows.
Your stronghold has gates but as mentioned previously, you only have 6-10 NPCs to man them. They're not military-grade gates anyway; let's say they're thick wooden gates, AC 15 and 400 HP to shatter them. Suitable for stopping bandits long enough to kill them. The palisade walls are about the same, 10' high and AC 15 and 600 HP per 10' section, with a 5' wide 10' deep ditch just outside them. Your stronghold is on high ground (crest of a small hill) and the area around it has whatever terrain you want--presumably you'll want the brush all around to have been cut back to a distance of a quarter-mile or more.
You don't know yet what the Fire Giants' tactics will be.
