What were the dates of the campaign that eventually led to the Treaty of Roskilde?
Treaty of Roskilde The Treaty of Roskilde was concluded on 26 February (OS) or 8 March 1658 (NS) during the Second Northern War between Frederick III of Denmark–Norway and Charles X Gustav of Sweden in the Danish city of Roskilde. After a devastating defeat, Denmark-Norway was forced to give up a third of its territory to save the rest, the ceded lands comprising Blekinge, Bornholm, Bohuslän (Båhuslen), Scania (Skåne) and Trøndelag, as well as her claims to Halland.
Siege of Rheinberg (1601) The Siege of Rheinberg also known as the Rhine campaign of 1601 was the siege of the towns of Rheinberg (Old Dutch: Rijnberk) and Meurs from June 12 to 2 August 1601, 1601 during the Eighty Years' War and the Anglo–Spanish War. Maurice of Orange with an Anglo-Dutch army besieged the Spanish held cities in part to distract them before their impending siege at Ostend. Rheinberg, an important city, eventually capitulated on July 28 after a Spanish relief force under Herman van den Bergh failed to relieve the city. The towns of Meurs surrendered soon after.
