When the host of blacks led by Ser Garibald Grey and Lord Roderick Dustin marched south from the riverlands to Tumbleton, they were joined by men from the Blackwater Rush, including Roger and Lord Owain Bourney. Roger was secretly a supporter of King Aegon II Targaryen, however. When the Two Betrayers began attacking the blacks during the First Battle of Tumbleton, Roger ordered his men to open Tumbleton's gates to the greens, while Owain did the same at the town's castle.
The greens' commanders regrouped in Tumbleton and planned what to do next, with Roger among those wanting to attack the black-held King's Landing. The two baseborn dragonriders Ulf White and Hugh Hammer proved difficult to deal with. Ulf desired Highgarden, while Hugh had designs on claiming the Iron Throne. Hugh wore a black iron crown, enraging Prince Daeron Targaryen. Roger angered Hugh by knocking off his crown, which led to Hugh nailing three horseshoes to Roger's skull. Roger's supporters tried to intervene, resulting in three dead and twelve wounded.
