The Dance of the Dragons
Prince Jacaerys Velaryon visited White Harbor and Winterfell and enlisted the North for the blacks during the Dance of the Dragons. Lord Manderly sent his sons, Ser Medrick and the clever, corpulent Ser Torrhen, to aid Rhaenyra Targaryen. After Rhaenyra lost two dragons to the Two Betrayers, the Manderly brothers argued that Addam Velaryon and Nettles were also untrustworthy.
During the riots at King's Landing, Torrhen's northmen found Fishermonger's Square and River Row to be swarming with the gutter knights of Ser Perkin. Torrhen's force lost a quarter of their men while retreating back to the Red Keep. The Manderly brothers accompanied Rhaenyra when she fled the capital after the Storming of the Dragonpit. Medrick asked Rhaenyra to travel to White Harbor, but she insisted on sailing instead to Dragonstone without the Manderlys.
Regency of Aegon III Targaryen
Ser Torrhen was named as one of Aegon III Targaryen's original seven regents, but eventually gave up his position in 132 AC to take up the Lordship of White Harbor after the death of his father and brother from winter fever. Lord Torrhen eventually returned to King's Landing and became Hand of the King during the regency of Aegon III until the king became of age and sacked all his regents and Hand.
