The Battle of Honsehuse was fought on 27 February 868 between Bjorn Tall-Trunks' Danish warband and a raiding party of invading Franks under Chlodion Unroching near present-day Schleswig, Schleswig-Holstein, Germany.
Bjorn had recently destroyed a fighter's camp near Hedeby, and he built up a warband from rural Danish freeholders. He later found a band of 28 Frankish raiders under Chlodion Unroching pillaging the rural areas on the north bank of the Schlei inlet in Anglia. The two sides met in battle at Honsehuse, now a district of the town of Schleswig.
The Franks charged into the Danish archers as they fired on their foes, killing several of them. Bjorn threw himself into the fray to turn the tide, as 36 of his 40 men were either killed or lightly wounded. He took part in the slaughter of the Frankish raiders, wounding and capturing 14 of them; he went on to release them, as he did not wish for them to slow down his warband.
