Under the cover of the night and fog, from the west, a fleet of ships was sailing quietly towards the mouth of the Honeywine. The fog was so thick that the invaders were not noticed until they had already passed the water entrance of Oldtown and were nearing the main docks. The alarm quickly rang, and men were sent to raise the chain. But by the time the city watch had started raising the chain to block the city's waterway, most of the Ironborn had already sailed in, leaving only a dozen or so galleys outside the city.
