Alsen (Schleswig-Holstein War).

This island, in which the Danish garrison of Düppel had taken refuge, was captured by the Prussians, who crossed from the mainland in boats on the night of June 29, 1864, and under a heavy fire carried the Danish entrenchments, and compelled them to surrender. This was the last engagement of the war.
