It's the 12th March 1868 and Prince Alfred, the Duke of Edinburgh and second son of Queen Victoria is visiting Australia. It's the first ever Royal Tour of the Australian colonies. He is invited by Sydney's high society to attend a popular picnic spot at Clontarf.

But not all is well in Australia. There is sectarian strife between the Irish Catholics and the British Protestant elite. At the picnic an Irishman called Henry James O'Farrell draws his pistol and fires a shot at Prince Alfred. The shot hits the Prince in the back.
