Hundreds of vessels were sunk by U-boats and Allied submarines during World War I, from the Mediterranean to the South Atlantic to the Pacific.
Somehow, hospital ships became caught up in the carnage - and New Zealand was dragged into it.
The Naval Defence Act of 1913 gave birth to the New Zealand Naval Forces, as they were first called. New Zealand asked Britain for training and equipment, and HMS Philomel was given to us on July 15, 1914 - to be used strictly as a training vessel. World War I erupted two weeks later.
The next step was for New Zealanders to train by serving in the Royal Navy on the Psyche and Pyramus, which escorted the NZEF to Samoa. After that we had to organise our first battle cruiser, HMS New Zealand, which helped the British fight Germany at the Battle of Jutland in 1916.
Around this time, the practice of laying mines in key shipping routes steadily turned into routine attacks on hospital ships. Usually those ships were sunk with torpedoes; occasionally U-boats would point their weapons at a vessel, order its occupants out, and destroy the vessel.
