The king arrived in Nyborg at 2:00a.m. on 5 February. It was stated in the morning that the ice condition became more uncertain in this section. Several Swedish patrols testing the ice at Korsør fell through but managed to save themselves from drowning. Sudden changes in the weather obstructed the ice formation, including storms and thawing. The king contemplated withdrawing the bulk of his army to Jutland and leaving a couple of infantry regiments as an occupying force on Funen, concentrated around Odense. He considered starting negotiations with King Frederick III and appointed Ulfeldt and council member Sten Nilsson Bielke as his delegates to deliberate with their Danish counterpart, Steward of the Realm Joachim Gersdorff and council member Christen Skeel. He suggested the Swedish and Danish delegations should meet in Rudkøbing on 13 February, alternatively on Sprogø. Swedish patrols were dispatched to investigate the ice towards Falser, Langeland and Lolland. They reported the change of weather had not affected the ice conditions in the southern part of the Great Belt.
