Siege of Skanderborg
The siege of Skanderborg, alternatively the siege of Skanderborg Castle, was a siege of the Holsteinian-held Skanderborg Castle in Jutland by Jutish rebels led by Niels Ebbesen. Despite being close to surrendering, the Holsteinian garrison received a relief force led by Henry II of Holstein-Rendsburg and defeated the Danes in the Battle of Nonnebjerg on 2 November 1340.
Background
In the early 14th century, Denmark was effectively subjugated to foreign powers, with Count Gerhard III of Holstein-Rendsburg exercising dominion over a significant portion of the country by the 1330s. However, a group of 50 Jutes, led by minor nobleman Niels Ebbesen, who were furious with the current regime, took matters into their own hands in 1340. They ambushed and assassinated Count Gerhard in Randers, a move that sent shockwaves throughout the country. In the aftermath, Ebbesen and his followers escaped through a bridge, fleeing south across the Gudenå to the Skjern River.At Skjern River, Ebbesen and his men stormed a Holsteinian fort construction possibly near present-day Skjern, and killed a great number of Germans. After this, Ebbesen continued his revolt, seeking the important castle of Skanderborg.
