The great green host that had taken Tumbleton did not march on. Fat with plunder and leaderless in all but name, it festered amid the ruins, and the two dragonseeds whose treason had won the town began to quarrel over the spoils of their betrayal. Hard Hugh Hammer, base-born but bold, dreamed openly of a crown for himself, reasoning that a man who rode the mighty Vermithor had as much right to rule as any Targaryen; Ulf the White drowned his ambitions in wine. The camp seethed with rivalries and murder, and Lord Ormund Hightower and Prince Daeron struggled to hold their unruly army together.
Into this discord flew Addam Velaryon upon Seasmoke. A dragonseed himself, and lately fallen under suspicion at court for the sins of his fellows, Addam meant to prove the loyalty of his kind in blood. He fell upon the encamped greens without warning, his dragon breathing fire down the length of the sprawling host. The camp erupted into a second battle more chaotic and murderous than the first. In the confusion Bold Jon Roxton slew Hard Hugh Hammer with his Valyrian blade Orphan-Maker, only to be cut down himself soon after; Lord Ormund Hightower fell in the carnage; and the dragons Seasmoke and Vermithor grappled in the air and upon the earth until both were slain, and Addam Velaryon died with his mount. Ulf the White survived to yield what remained of the town, though poison would take him before long.
When the fires guttered out, Tumbleton was a charnel house twice over, and the mighty host that Lord Hightower had led out of the Reach was a leaderless wreck, its captains dead and its dragons burned. The march upon King's Landing that had seemed unstoppable was broken utterly, and neither side could claim the field with any honor. The maesters count the Second Battle of Tumbleton among the strangest and most ruinous engagements of the Dance, a battle won by no one, in which the greens destroyed themselves as surely as any enemy might have, and another two dragons were added to the war's terrible ledger.
