Emperor Vanish received information that led him to believe that his plan had worked. Since the Cheif of Joler withdrew his men, he had already lost at least twenty percent of his manpower. This time he was using some trick to tire the people from across the sea.
Since the men had been anxious for two days, laying an ambush for him, he was confident that they should be tried or give up by now. Even if they were keeping watch, they would definitely be easy to defeat.
So after keeping them anxious for two days, Emperor Vanish leads fifteen thousand men to the battle. He had gone with so many men because he wanted to crush the men like they did his men the last time. Sébastien was still in Bait, so he felt the battle would finish in a few hours.
