Cassius was the commander of the ground army and after a couple of weeks of march they were finally reaching Robert's hideout, it turned out after being defeated in Ashford Robert lost half his troops it seemed that just the vanguard of the Reach forces was in the ambush, and even then they lost the same amount of troops, it could be barely be called a victory since by the time their main force arrived Robert's forces were already on retreat and instead of chasing which would be detrimental since most of their forces were footmen and they would slow the rest of the army, so instead they attacked the stormlands and laid siege to their fortresses. Robert's forces took refuge in the Stoney sept but had in their tails a force sent by the crownlands, from the reports he could get they were twenty thousand strong, a mix between knights and sellswords since there were still soldiers defending kingslanding.
