|Result || Rebel victory - Robert wins three battles in a single day.|
The Battle of Summerhall was actually three battles fought in one day at the ruins of the Targaryen castle Summerhall in the Stormlands during Robert's Rebellion.
Lord Robert Baratheon managed to return to Storm's End after Gulltown and called his bannermen in rebellion against King Aerys II. However, some of the storm lords remained loyal to King Aerys and rejected his commands. The lords of Houses Fell, Cafferen and Grandison were going to join forces at Summerhall in the Dornish Marches and march on Storm's End to confront their liege lord. Robert, catching wind of it, raced with his forces to meet them.
Not much is known about the battle, only that Robert managed to arrive first and won three battles in a single day, defeating the forces of the three loyalist houses in turn as they arrived. Additionally, Robert killed Lord Fell in single combat.
Robert consolidated his power in the Stormlands, winning the support of the rest of the storm lords, which allowed him to march towards the Reach with no enemy loose in his rear.
Lord Fell was killed and his son Silveraxe, Lord Grandison and Lord Cafferen were captured and taken to Storm's End as prisoners. The three captives would later join the rebel cause after some time spent in captivity. Randyll Tarly killed Cafferen in the Battle of Ashford, while Grandison died after the war from a wound taken in the Battle of the Trident.
