- HMAS Australia joins the Grand Fleet as flagship of the 2nd battlecruiser squadron of the Grand Fleet
- Just four weeks after conducting the first-ever air raid in Britain, the Imperial German Navy Zeppelins L-3 and L-4 are forced down by severe weather off north-west Denmark while searching for Allied merchant vessels. The crew of L-3 burn the zeppelin before being captured and interned; L-4 ditches into the North Sea and disappears with four men still on board. The remaining 11 crew members are plucked from the sea and interned by Danish authorities.
