High Quality Content by WIKIPEDIA articles! The La Grange expedition was a search expedition carried out in the vicinity of Lagrange Bay in the Kimberley region of Western Australia in 1865. Led by Maitland Brown, the expedition searched for three settlers who had failed to return from an earlier exploring expedition. The three men were eventually found dead, having been speared and clubbed to death in their sleep by Indigenous Australians. A number of Indigenous people were subsequently killed by members of the expedition in a controversial incident that is often now referred to as the "La Grange Massacre", although the fairness of this term remains a matter of some debate.
