It's not an "article" as such but a letter from a reader like you or me, posted anonymously and replete with demonstrable falsehoods, such as that Wills arrived from England three years earlier (he and his father were born in NSW) and that his family's heads were impaled on sticks during the massacre (only his father was present). The writer also seems to be under the illusion that the events happened in Victoria. The dramatic supposed recounting of Wills' return to the property is at odds with a man not given to such introspection, least of all to a stranger. And there is documented evidence that Wills recuperated at a nearby station while the first reprisal raid was carried out. A later, more deadly raid was conducted under the auspices of the fearsome Queensland Native Police.
The letter is an interesting discovery after all this time, but in its full context must remain a dubious curiosity.
