On the morning of 30 January, the Danes located the Swedish vanguard, consisting of 400 cavalrymen under Colonel Casper Borneman, who rode out towards Tybrind Vig. 200 detached dragoons who used sleds to carry beams, boards, ladders, barrels, and straw to build bridges across gaps and weaker ice sections accompanied Borneman. After their discovery, the Danes dispatched some of their units from Iversnæs to Tybrind Vig, where they clashed with the Swedish scouts. The church bells rang across Funen, warning the Swedes were on their way. The Swedish soldiers put straw on their hats as a sign of identification and handed out the password: "Help, Jesus!".
