The Dano-Swedish War of 1657–1658, known in Denmark as the First Charles Gustav War (Danish: Første Karl Gustav-krig) in Norway as Krabbes Feud (Norwegian: Krabbefeiden) and in Sweden as Charles Gustav's First Danish War (Swedish: Karl Gustavs första danska krig), was a conflict between Sweden and Denmark–Norway during the Northern War of 1655–1660. In 1657, Charles X Gustav of Sweden and his Swedish army were Fighting in the Poland. Frederick III of Denmark-Norway saw an opportunity to recover the territories it lost in 1645 and attacked Sweden. The outbreak of war with Denmark provided Charles Gustav with an excuse to withdraw from the Polish campaign and move against Denmark.
After entering Jutland from the south, the Swedes then starting moving across Denmark, crossing the icy Little Belt onto the Danish island of Funen on 30 January 1658. The Swedes captured that island within a few days and then went on to capture the islands of Langeland, Lolland, and Falster. Zealand was taken in less than a year and the Swedish army was by that point threatening the Danish capital of Copenhagen. The rapid Swedish attack across the frozen Belts was completely unexpected; Frederick III considered meeting the Swedish army in battle, but his advisors thought this was too risky and instead Denmark-Norway signed the very harsh Treaty of Roskilde on 26 February 1658. With that, Sweden won its most prestigious victory, and Denmark-Norway had suffered its most costly defeat. Denmark-Norway yielded the Danish provinces of Scania, Halland, Blekinge and the island of Bornholm and the Norwegian provinces Bohuslen and Trondhjem len (Trøndelag and Nordmøre) to Sweden. Some of the territorial changes would be changed by another Dano-Swedish War.
