The Siege of Kalundborg (Danish: Belejringen af Kalundborg), also known as the Siege of Kalundborg Castle, was a siege by Valdemar IV of Denmark on the Norwegian-pledged Kalundborg Castle in 1341 during the Kalundborg War, which is named after the siege. The Danes were forced to retreat after a surprise attack on the Danish camp by Henry II, Count of Holstein-Rendsburg.
Background
editIn 1340, Valdemar IV of Denmark became king of a disunited and fragile Denmark. Denmark has previously been under the foreign rule of the German Count Gerhard III of Holstein-Rendsburg, and Valdemar now set about to reunite Denmark.[1]
Valdemar deemed Zealand to be the most important part of Denmark, and in 1341 he got control of Copenhagen which he could use as a base for further operations on Zealand.[2]
On Zealand, the castle of Søborg and Kalundborg was mortgaged to Ingeborg of Norway, and these would be the first targets for Valdemar.[3][4] Valdemar and his men marched to Kalundborg and had already started besieging the castle in mid-July 1341.[4]
Siege
editDuring his besieging of Kalundborg, Valdemar managed to receive support from 5 Wendish–Hanseatic cities.[5] In his camp, he made an alliance with the Wendish cities on 15 July, in which they received renewed ratification on their free letters, for helping Valdemar with warships during his siege.[4] Additionally, Valdemar received support from Count John III of Holstein-Plön and Bishop Peder Jensen from the Archbishopric of Lund, who both promised to send ships to Valdemar's disposal.[4]
However, without a declaration of war, Henry II, Count of Holstein-Rendsburg showed up at Kalundborg with many warships and fell over Valdemar's vessels, which either deserted the action or were enclosed.[6] Seeing this, the garrison in the castle made an outcome out of the castle, and Valdemar was subsequently forced to abandon his siege.[6][7]
Aftermath
editOn 1 September, an agreement was made between the two parties, in which four men from each side would meet at Roskilde on Michaelmas to settle the feud between Ingeborg and Valdemar. However, the results of these negotiations are unknown.[8]
