The Surafend massacre is perhaps New Zealand's darkest military story.
Some 200 members of the Anzac Mounted Division killed upwards of 40 male Arab civilians in a small village in southern Palestine in December 1918.
It is a shocking story that kicks off the latest season of the Black Sheep podcast.
Creator and presenter William Ray says 100 years later, much of the story around the massacre remains a mystery.
The latest season of the podcast will also traverse stories about early missionaries in the 1810s as well as a famous teenage highwayman in Taranaki.
Black Sheep is among RNZ's longest-running podcasts. It won podcast of the year at last year's NZ Podcast Awards.
