Christian IV was fortunate not to have lived to witness one of the darkest days of Danish loss. By the terms of the Treaty of Roskilde, signed a decade later in 1658, the Danes were forced by the Swedes to relinquish what are today the southern Swedish regions of Skåne, Blekinge and Halland, as well as the Baltic island of Bornholm (the latter was eventually returned and remains Danish).
