To prevent French claims, Governor Darling dispatched Major Edmund Lockyer, in 1827, in the brig Amity, to assume possession for the English crown of New Holland, at King George Sound, a natural strategic harbour. Two years later, Governor James Stirling, established Perth, as the capital of the Swan River Company settlement, beginning the human settlement geography of Western Australia. Stirling, as a naval man, chose three sites that were easily defensible as the major towns for the colony. Fremantle, situated beneath the Monument, was to be the port, Perth, surrounded by water on three sides, with the barracks defending its western entrance, was to be the capital, and Guildford, also surrounded by water to the west south and north (the loop of the Swan and Helena Rivers), was to be the agricultural centre. Similar easily defended sites were chosen in the case of Australind and Bunbury, and Augusta. No account was taken of the wishes or desires of the indigenous Aboriginal people, who were progressively excluded from traditional lands owned by them.
