Leslie was furious with Banér and in his own account of the battle infers there had been a dispute about the tactics for the day. As it was, Leslie was forced to sacrifice many of his veteran troops in the process of saving Banér's men from being routed. Leslie intimated to Oxenstierna that he would stand down from Swedish service but was persuaded to remain and restructure the Army of the Weser. However, by 1637, Leslie was in Scotland preparing the way for his final retirement from Swedish service. He cherished his old commander's memory to the day of his death, and he kept with particular care a jewel and miniature presented to him by the king.
