The Danish commander Daniel Rantzau had been forced to yield the fortress Varberghus to the Swedes on September 15, 1565, after they had taken Ny Varberg, then Halland's largest city. Rantzau received the news that a Swedish army of superior strength led by Jacob Henriksson Hästesko was approaching from the east forced him to move his forces toward Falkenberg. Rantzau had decided to commit to combat since the Swedish force had just arrived from its march and hadn't rearranged into a militarily cohesive unit.
