This turn to my affairs surprised, and at first stunned me. The single circumstance about which I had entertained the least apprehension, was the neglect in my passport of providing for any other vessel than the Investigator; but from this order of the captain-general, I found myself considered in the light of a spy; my desire to know how far Mauritius could be useful as a place of refitment in the future part of my voyage--a desire formed and expressed in the belief of its being a time of peace, was made a plea for depriving me of liberty and the result of more than two years of risk and labour. The sensations raised by this violation of justice, of humanity, and of the faith of his own government, need not be described; they will be readily felt by every Englishman who has been subjected, were it only for a day, to French revolutionary power. On returning to my place of confinement, I immediately wrote and sent the following letter, addressed to His Excellency the captain-general De Caen, governor in chief, etc. etc. etc. Isle of France.

Sir,

From your order, which was explained to me this morning, I find that the plea for detaining me is not now that I do not appear with the Investigator, according to the letter of my passport from the first consul of France; but that I have violated the neutrality therein required by having given in my journal, as an additional reason for putting into this port, that "it would enable me to acquire a knowledge of the periodical winds, and of the present state of the French colony; how far it or its dependencies in Madagascar might be useful to Port Jackson, and how far it would be a convenient place for me to touch at in my future expected voyage:" I quote from memory only, my journal being in your possession. How this remark, made upon the supposition of our two nations being at peace, can be a breach of neutrality, I acknowledge myself unable to discover. Nothing can, in my opinion, add to the propriety of the intentions with which I put into this port, but I shall justify it by the example of your own nation; and to do so, it is only necessary for me to refer to the instructions which preface the published voyage of the unfortunate La Pérouse, by the judicious Fleurieu. Your Excellency will there see, that the much lamented navigator was ordered to make particular observations upon the trade, manufactures, strength, situation, etc. of every port where he might touch; so that, if the example of your own nation be taken as a standard of propriety, the plea for making me a prisoner is altogether untenable. Upon the supposition even of its being war, and that I knew it and still intended to make the observations expressed in my journal; upon this incorrect and worst supposition I have, I think, an example of similar conduct in your own nation; unless you can assure me that the captains Baudin and Hamelin made no such remarks upon Port Jackson, for it was a declared war at the time they lay in that port. But were they forbidden to make such remarks and notes upon the state of that English colony? Upon its progress, its strength, the possibility of its being attacked with advantage, and the utility it might afford to the French nation? I tell you, general De Caen, No. The governor in chief at Port Jackson knew too well the dignity of his own nation, either to lay any prohibition upon these commanders, or to demand to see what their journals might contain.

I shall next appeal to you as being the representative in this place of a great nation, which has hitherto shown itself forward to protect and encourage those sciences by which the knowledge of mankind is extended or their condition ameliorated. Understand then, Sir, that I was chosen by that patron of science sir Joseph Banks, president of the Royal Society of London, and one well known by all the literati throughout the world, to retrace part of the track of the immortal captain Cook--to complete what in New Holland and its neighbourhood he had left unfinished--and to perfect the discovery of that extensive country. This employment, Sir, as it was congenial to my own inclinations, so I pursued it with avidity; upon it, as from a convex lens, all the rays of knowledge and science which my opportunities have enabled me to collect, were thrown. I was unfortunate in that my ship decayed before the voyage was completed; but the captain-general at Port Jackson, who is also the senior naval officer there, was so sensible of the importance of the voyage and of the zeal with which I had pursued it (for the truth of which I appeal to his letters now in your possession), that he gave me a colonial ship of war to transport me with my officers, charts, etc. to England, that I might obtain another ship in which the voyage might be completed. In this second ship I was a passenger; and in her, shipwreck and the loss of charts which had cost me much labour and many risks to make perfect, were added to my first misfortune; but my zeal suffered no abatement. I returned to Port Jackson (734 miles) in an open boat, and got a merchant ship which was bound to China, hired to carry my officers and people to England by that circuitous route; but desirous of losing no time, I took a small schooner of twenty-nine tons, a mere boat, in order to reach England by a nearer passage, and thus gain two or three mouths of time in the outfit of my future expected ship; making my own case and safety to stand in no competition with the great object of forwarding my voyage. Necessity, and not inclination, obliged me to put in at the Isle of France in my route.

Now, Sir, I would beg to ask you whether it becomes the French nation, independently of all passport, to stop the progress of such a voyage, and of which the whole maritime world are to receive the benefit? How contrary to this was her conduct some years since towards captain Cook! But the world highly applauded her conduct then; and possibly we may sometime see what the general sentiment will be in the present case.

I sought protection and assistance in your port, and I have found a prison! Judge for me as a man, Sir--judge, for me as a British officer employed in a neutral occupation--judge for me as a zealous philanthropist, what I must feel at being thus treated.

At present I quit the subject with the following requests: that I may be permitted to have my printed books on shore; and that my servant may be allowed to attend me in my apartment.

With all the respect due from my situation to the captain-general,

I am From my confinement, Your Excellency's obedient servant, Dec. 21, 1803. Matthew Flinders.

The lapse of several years has enabled me to consider the transactions of this period under different views, to regard them with almost the coolness of an uninterested observer; and I see the possibility that a dispassionate reader may accuse me of taking too high a position, and using too warm a style--in rather giving way to the dictates of feeling than dwelling upon the proofs of my innocence; perhaps also, he may accuse me of vanity, in seeking to enhance my own zeal and claims. Without attempting to controvert these censures, I beg him to consider all the circumstances of my situation: my voyage, shipwreck, and anxiety to pursue the steps of our celebrated navigators. Let him suppose himself to have executed so much of the same task, escaped the same dangers; and under the influence of powerful motives to reach England with expedition, to be arrested on the way, his misfortunes either not heeded or converted into proofs of delinquency, and himself treated as a spy; and this is done by the representative of a government which had promised assistance and protection, and moreover owed him a return for the kind treatment recently experienced by Frenchmen in the port from whence he came. Let him suppose himself writing to his oppressor with these various recollections crowding on his imagination; and the allowances he would then desire for himself, I request of him to make for me.
