In an attempt to make peace, Gandalf allowed General Haul to get back to his horse and lead his men to his cause. "We have the same enemy; I say we ally ourselves together" he said to the general. Even though Lucian Mithandir lost and probably Prince Ambrose was also dead in Stonedance, General Haul decided to support Lord Gandalf.
Henceforth, forty thousand men all on horses rode back to the King's City from the Green Mountains gates. It was a long ride but they rode faster and all day without rest, while Castellan was marching slowly towards his own city. He wasn't in haste to meet his death, however he wished to bargain his sons lives with his.
