1632 Battle of Alte Veste in 1632 Lützen in 1632 Nördlingen in 1634 Leipzig in 1642 (also known as the Second Battle of Breitenfeld or the First Battle of Leipzig) Jankau in 1645 200 Hakkapeliitta were also part of the army which King Karl X Gustav of Sweden led across the frozen Danish straits in the winter of 1658, which enabled him to conquer Skåneland from Denmark in the Treaty of Roskilde. Many Finnish soldiers served under the Swedish Empire. During the era of the Swedish Empire of the 17th century, the Finnish cavalry was constantly used in Germany, Bohemia, Poland, and Denmark. Parts of the cavalry were stationed in Estonia and Livonia. In popular culture The Bearkillers, a protagonist faction in S.M. Stirling's Emberverse series, uses the Hakkapeliitta battle cry. The module of the Advanced Squad Leader board game system, depicting the Finnish forces in World War II, is titled Hakkaa Päälle! Nokian Tyres makes snow tires called Hakkapeliittas. Hakkapeliitta's feature in Eric Flint's 1632 novel series as one part of Gustav II Adolf's armies. The song "Rex Regi Rebellis" by Finnish metal band Turisas describes the adventures of the Hakkapeliitta and includes the battle cry Hakkaa päälle pohjan poika! (Strike them down, son of the North!). The Hakkapeliitta is included in the video game Age of Empires III as a mercenary unit, under the name hackapell. When Age of Empires III: Definitive Edition released, the Hackapell mercenary was removed and replaced with a more generic "Harquebusier" unit. This is due to the introduction of a full Swedes civilization, who can field non-mercenary Hakkapelit from the Stable. While historically the Hakkapeliitta are light cavalry, the game classifies them as Heavy Cavalry. In Civilization V, the Hakkapeliitta are a unique unit of the Swedish Empire under Gustavus Adolphus.
