From A Wiki of Ice and Fire
When King Viserys I Targaryen brought his court to Driftmark for the funeral of of Ser Laenor Velaryon in 120AC, the number of dragons gathered on the island led Septon Eustace to call it the New Valyria.
During the Dance of the Dragons, Lord Corlys Velaryon, the Sea Snake, launched black ships from Hull and Spicetown to block access to Blackwater Bay. High Tide and Spicetown were burnt in the Battle in the Gullet, the latter so severely it was not rebuilt.
