Battle of Bornhöved (1227)
The (second) Battle of Bornhöved took place on 22 July 1227 near Bornhöved in Holstein. Count Adolf IV of Schauenburg and Holstein — leading an army consisting of troops from the cities of Lübeck and Hamburg, about 1000 Dithmarsians and combined troops of Holstein next to various Northern German nobles — defeated King Valdemar II of Denmark and the Welf Otto the Child.

The contest was maintained with great firmness on both sides, and continued for an unusual length of time, and the carnage was so great, that its combatants are said to have fought knee deep in blood. The King of Denmark had one of his eyes shot out, and had several horses killed under him, but his troops and their allies fought with so much bravery that the victory would have been theirs had not the contingent of Dithmarschen, a Saxon ethnic group, deserted their colours. At the most critical moment of the action these troops passed over to the enemy, and the Danes were obliged to give way. In the confusion that followed Otto I, Duke of Brunswick-Lüneburg and the Bishop of Ribe were taken prisoner. Otto was sent to Rostock, the capital of a lordship held by Mecklenburg, where he was shut up in a fortress. But the King of Denmark, who escaped from the field, busied himself in repairing this disaster by forming a fresh army, with which he kept the enemy in check.
As a result of the battle, the Danish border with the Holy Roman Empire was moved north again from river Elbe to the Eider River, the southern border of the Duchy of Schleswig. This border remained in effect until 1806. The victorious Adolf IV of Schauenburg regained the County of Holstein and his fellow victor Albert I, Duke of Saxony reasserted himself as liege lord of the Counts of Schauenburg and Holstein against the Welf claim. Dithmarschen shook off Danish supremacy and returned to a very loose overlordship by the Prince-Archbishopric of Bremen, paving the way for its de facto autonomy as a peasant republic until 1559. The Principality of Rügen was the only possession in the Holy Roman Empire left to Valdemar after the battle.
