On April 18, 1864, the city of Dybbol, located in the Duchy of Schleswig, was attacked. The duchy had been attacked by Prussian and Austrian forces in January of that year, and Dybbol, with its location overlooking the Flensburg Fjord and its fortifications, was an important strategic position. Despite the valiant resistance put up by the Danish soldiers, they were outnumbered by the Prussians and Austrians and forced to retreat.
