Battle of Halmstad The Battle of Halmstad ( also known as the " Battle at Fyllebro " ) was fought on August 17 , 1676 , at Fyllebro , approximately five kilometers south of the town Halmstad in southwest Sweden . It was the last battle in Halland between Denmark and Sweden . Prelude . The Danish army that landed at Helsingborg in Scania in late June 1676 managed to conquer almost the whole province in less than a month . The Swedish army had to retreat north to Växjö . In early August , General Jakob Duncan with about 4 , 000 Danish troops was sent north , to the province of Halland , to take Halmstad and if possible advance further north to join General Ulrik Frederick Gyldenløve , who had reached Gothenburg with a Norwegian army and was threatening to besiege the city . On August 11 , King Charles XI and his small army headed west to intercept Duncan . General Duncan had been informed about Swedish troops heading in his direction but as he assumed that it was just a smaller unit under General Ascheberg , he made no haste when he decided to leave Halmstad and return south to Scania . At noon of August 17 , the Swedish army reached the only road from Scania to Halmstad and Duncan was trapped . The Swedes destroyed the bridge leading south and headed north . The battle . After just a few kilometres the Swedish vanguard under command of Ascheberg encountered a small Danish unit that was routed back north . After a short chase Ascheberg found himself face - to - face with Duncan and his forces . The Danish army was about to cross the bridge over the creek " Fylleån " . Duncan , who thought that the approaching enemy troops were the entire Swedish force , continued to let his men cross the bridge . Unaware of the danger he let his troops assume battle formations on the south bank with their backs against the creek . Meanwhile , the Swedes brought forward the rest of their cavalry and infantry , which had been lagging behind . The battle started with a salvo from the few Swedish cannons , whereupon Charles XI and his Household cavalry charged down the hills to attack the Danish left wing . Soon the Swedes also charged on the left wing and in the center . After 15 minutes the Danish left wing was scattered . In the center the Danish infantry put up a determined fight , with a powerful counter - attack from a cavalry unit that tried to break through the Swedish lines , but only one squadron made it through . At this point Duncan had realized his mistake and ordered his remaining troops to retreat back across the bridge . But the Swedish cavalry on the right wing found a ford and started moving fresh cavalry squadrons across the creek . Understanding that the battle was lost , Duncan surrendered . The action had lasted for little more than an hour . Aftermath . The defeat at Halmstad dealt a hard blow to the Danish plans to advance north and to make contact with the Norwegian army . The day after the battle the Danish King Christian V broke his camp at Kristianstad and started marching towards Halmstad . On September 5 he reached Halmstad and begun besieging the town with no result . Three weeks later he returned to Scania to find quarters for the winter . The battle at Fyllebro was also 20 - year - old Charles XI ' s first major victory . It was an important morale boost for him , his generals , and the whole Swedish army . The army was still much too weak to confront the Danes in Scania and marched north to Varberg to await more troops .
