The Prussian forward artillery batteries in front…
April 1864 CE
The Prussian forward artillery batteries in front of Dybbøl had started to bombard the fortifications and the town of Sønderborg on April 2, continuing until April 18, firing about sixty-five thousand shells at the Danish positions.
A Prussian attack on Dybbøl had been repulsed on April 4.
At 10 a.m. on the 18th, ten thousand Prussian soldiers storm the Danish fortifications at Dybbøl after six hours of artillery preparations and take Dybbøl fort.
The Danish 8th Brigade fails in a courageous counterattack, suffering thousands killed or wounded.
