Own the rights?
Yes, but... The history of the affair is somewhat muddled. The trial transcript was lost, so the only good source of information is Lt. Witton's book, "Scapegoats of the Empire". News accounts of the events and trial were censored until months after the execution. Further problems were created by a fictionalized account published in the 60's, pieces of which were subsequently reported as fact in other histories. see http://en.wikipedia.org/wiki/Breaker_Morant#Events_leading_to_Morant.27s_arrest for a longer discussion.
