"The conquest of Port Jackson would be very easy to accomplish, since the English have neglected every species of means of defence. It would be possible to make a descent through Broken Bay, or even through the port of Sydney itself; but in the latter case it would be necessary to avoid disembarking troops on the right side of the entrance, on account of the arm of the sea of which I have already spoken.* (* Middle Harbour.) That indentation presents as an obstacle a great fosse, defended by a battery of ten or twelve guns, firing from eighteen to twenty-four-pound balls. The left shore of the harbour is undefended, and is at the same time more accessible. The town is dominated by its outlying portions to such an extent, that it might be hoped to reduce the barracks in a little time. There is no battery, and a main road leads to the port of Sydney. Care ought to be taken to organize the invaders in attacking parties. The aboriginals of the country need not be reckoned with. They make no distinctions between white men. Moreover, they are few in numbers. The residence of the Governor, that of the colonel of the New South Wales Regiment, the barracks, and one public building, are the principal edifices. The other houses, to the number of three or four hundred, are small. The chief buildings of the establishment captured, the others would fall naturally into the hands of the conqueror. If the troops had to retreat, they would best do so by the River Oxbury* (* i.e., the Hawkesbury; the Frenchman guessed at the spelling from the pronunciation.) and thence to Broken Bay. I regret very much that I have not more time to give* to this slight review of the resources, means of defence of and methods of attack on that colony. I conclude by observing that scarcely any coinage is to be found in circulation there. They use a currency of copper with which they pay the troops, and some paper money." (* Compare Peron's remark concerning the little time at his disposal. Both reports were written only a few days before Le Geographe left Ile-de-France for Europe.)
