A Storm of Swords
At Tumbler's Falls, Lord Tywin Lannister joins Lord Mace Tyrell, who has brought barges and a large host with him. From there they sail down the Blackwater Rush and land a half day's ride outside of King's Landing. They take Stannis Baratheon's army in the rear during the Battle of the Blackwater.
Not finding Ser Jaime Lannister in Tumbler's Falls after his escape from Riverrun, a group of northmen proceed to rape and murder, killing eight people. They are apprehended by the Mad Huntsman, however, and put in crow cages in Stoney Sept to die. Anguy eventually puts three surviving northmen out of their misery.
