Only four weeks after they became the first two airships to bomb the United Kingdom, the Imperial German Navy Zeppelins L-3 and L-4 are wrecked in Denmark while attempting to search for British ships off Norway. L-3 ’​s crew burns her before being interned by Danish authorities. L-4 is blown out over the North Sea after touching down in Denmark and disappears with four men still on board; the Danes intern the rest of her crew.
