The Battle of Helsingborg was the last major engagement of the Great Northern War to take place on Swedish soil, and resulted in a decisive victory of a Swedish force of 14,000 men under the command of Magnus Stenbock against a Danish force of equal strength under the command of Jørgen Rantzau, ensuring that Denmark's final effort to regain the Scanian territories that it had lost to Sweden in 1658 failed. The battle was fought on March 10, 1710, in the province of Scania, just outside the city of Helsingborg, and directly on the Ringstorp heights just north-east of the city.Denmark-Norway had been forced out of the Great Northern War by the Treaty of Traventhal in 1700, but had long planned on reopening hostilities with the goal of reconquering the lost provinces Scania, Halland and Blekinge. After the Swedish defeat at Poltava in 1709, the Danes saw an opportunity and declared war on Sweden the same year. The declaration of war arrived at the Swedish state council on October 18, 1709. The pretext given was that Sweden had been intentionally trying to avoid paying the Sound Dues, and that the population of Scania, Halland, Blekinge and Bohuslän had been mistreated by the Swedish.In January 1710 the Danish invasion force defeated a smaller Swedish force outside Kristianstad in a small skirmish. On March 10, 1710, the Danish force finally engaged the Swedish army, which had been hastily drafted from the surrounding regions to try to resist the Danes. The Swedish cavalry carried the day during the engagement, with the Danish lines crumbling and retreating under repeated charges. The battle proved to be a total rout for the Danes, with more than half of their force killed, wounded or captured. The battle ended any hopes for the Scanian territories to return to Danish rule, and the territories became a permanent part of Sweden.
