Wahlan orders his fleet to investigate after learning of fleet movements inside the Iserlohn corridor. On the Imperial side of the corridor, Julian approaches Imperial admiral Wagenseil's fleet. Using strike craft and a slow withdrawal strategy, Julian infuriates Wagenseil. The Wagenseil fleet is lured into range of the Iserlohn Thor hammer cannon and loses a large portion its ships. Wahlan's fleet tries to attack Iserlohn from the back before the Thor hammer recharges. Merkatz ambushes Wahlan's fleet from a blind spot while Julean approaches from around the fortress, executing a pincer formation. The Thor hammer fires two more times, causing massive damage to the pincered Wahlan fleet. Reinhard prepares for a counterattack from Phezzan, but is bedridden with a high fever.
