Hall of Infinite Doors

Because you didn't alert the rest of the guards and you didn't see a SIGNAL for what it was, the giants get very close to the edge of the forest and charge a surprise attack upon the town. Though the walls are strong, the number of giants is great and they bore down upon the city like an avalanch. Many are slaughtered, but most escape to a safer haven to prepare for another assault. Unfortunately, you're not one of them.
