- "When a new army of Green loyalists marched up from the Reach and laid siege to the city of Tumbleton, Rhaenyra sent two of her dragonseeds to lay waste to them. Instead, the dragonseeds proved their bastard nature and betrayed her. They burned the city and all the Black forces garrisoned within."
- ―Viserys Targaryen

In the books
In the A Song of Ice and Fire novels, Ulf the White and Hugh Hammer were sent to Tumbleton with their dragons Vermithor and Silverwing to subdue an army of Greens led by Lord Ormund Hightower. House Caswell of Bitterbridge and House Merryweather of Longtable joined the Blacks at Tumbleton, as did the victorious Rivermen and Northmen from the Butcher's Ball. Their exact numbers have been a matter of some debate, with various sources claiming figures from 6,000 to 12,000. It is known theat they were greatly outnumbered by the Greens.
As the battle commenced, Ser Garibald Grey led six thousand men against Lord Hightower, whose archers thinned his ranks. Red Robb Rivers' bowmen defended Garibald's men as they retreated from Ormund's heavy horsemen. Lord Roderick Dustin led the Winter Wolves out a postern gate against the Hightower forces. Though the Northmen were outnumbered two to one, Roderick was able to reach Ormund and kill him and his cousin, Ser Brynden Hightower, before succumbing to his wounds.
With the Hightowers dead, the Black forces believed their victory ensured, and were not even dismayed by the appearance of Prince Daemon Targaryen's dragon Tessarion. However, Ulf and Hugh betrayed the Blacks and turned their dragons upon the town. Buildings turned to ash and thousands burned to death or drowned trying to flee across the Mander. One by one the leaders of the Black forces were killed and girls as young as eight were raped by their captors.
Upon hearing of the events at Tumbleton, Dowager Queen Alicent Hightower laughed, declaring that the Blacks were reaping what they had sowed. The smallfolk of King's Landing feared that a similar attack would strike the capital, but Queen Rhaenyra Targaryen had the City Watch of King's Landing seal the city's gates to prevent them from fleeing. Following his cousin's death, Ser Hobert Hightower took command of the Green forces at Tumbleton.
