When he wrote his Voyage to Terra Australis, he had not his journal in his possession, and worked from notes of his recollections. In telling the story now, the author has before him not only what Flinders wrote in this way, but also a copy of the French translation of the journal which Decaen had prepared for his own use, and several letters written by Flinders, wherein he related what passed in his mind when he resolved to alter his course.

The first and most imperative reason was the necessity for repairing the ship and refitting the pumps. Secondly, rations had had to be shortened, and victuals and water were required. Thirdly, Flinders had come to the conclusion that the Cumberland was unfit to complete the voyage to England, and he hoped to be able to sell her, and procure a passage home in another ship. "I cannot write up my journal unless the weather is extremely fine," he wrote. Fourthly, he desired "to acquire a knowledge of the winds and weather at the island of the actual state of the French colony, of what utility it and its dependencies in Madagascar, might be to Port Jackson, and whether the colony could afford me resources in my future voyages."* (* Journal.)

When he sailed from Port Jackson there was, as far as he knew, peace between England and France. But there was a possibility that war had broken out again. In that event, the thought occurred to him that it would be safer to call at the French colony than at the Cape, since he had a passport from the French Government, but not from the Dutch, who would probably be involved in hostilities against England. He did not forget that the passport was made out for the Investigator, not for the Cumberland. "But I checked my suspicions by considering that the passport was certainly intended to protect the voyage and not the Investigator only. A description of the Investigator was indeed given in it, but the intention of it could be only to prevent imposition. The Cumberland was now prosecuting the voyage, and I had come in her for a lawful purpose, and upon such an occasion as the passport allowed me to put into a French port. The great desire also that the French nation has long shown to promote geographical researches, and the friendly treatment that the Geographe and the Naturaliste had received at Port Jackson, rose up before me as guarantees that I should not be impeded, but should receive the kindest welcome and every assistance."* (* Flinders to Fleurieu; copy in Record Office, London. An entry in his Journal shows that only when he was informed that the war had been renewed did it occur to Flinders that the French authorities would interpret literally the fact that the passport was granted to the Investigator.)

He had no chart of Ile-de-France, but a description in the third edition of the Encyclopaedia Britannica informed him that the principal harbour, Port Louis, was on the north-west side, and thither he intended to steer.

On December 15th the peaks of the island showed up against the morning sky. At noon the Cumberland was running along the shore, close enough to be observed, and made a signal for a pilot from the fore-topmast head. A small French schooner came out of a cove, and Flinders, wishing to speak with her to make enquiries, followed her. She ran on, and entered a port, which proved to be Baye du Cap (now Cape Bay) on the south-west coast. Flinders steered in her wake, thinking that she was piloting him to safety. The truth was that the French on board thought they were being pursued by an English fighting ship, which meant to attack them; and immediately they came to anchor, without even waiting to furl sails, they hurried ashore in a canoe and reported accordingly. Thus from the very beginning of his appearance at Ile-de-France, was suspicion cast on Flinders. So began his years of sore trouble.

It was evident from the commotion on shore that the arrival of the Cumberland had aroused excitement. Flinders saw the people from the schooner speaking to a soldier, who, from the plumes in his hat, appeared to be an officer. Presently some troops with muskets appeared in sight. Apparently orders had been given to call out the guard. Flinders concluded that a state of war existed, and hastened to inform the authorities by sending Aken ashore in a boat, that he had a passport, and was free from belligerent intentions.

Aken returned with an officer, Major Dunienville, to whom the passport was shown, and the necessities of the Cumberland explained. He politely invited Flinders to go on shore and dine with him. It was pointed out that the immediate requirements were fresh water and a pilot who would take the ship round to Port Louis, as repairs could not be effected at Baye du Cap. The pilot was promised for the next day, and Major Dunienville at once sent a boat for the Cumberland's empty casks.

As soon as he got ashore again, Dunienville wrote a report of what had occurred to the Captain-General, or Military Governor of the island, General Decaen, and sent it off by a special messenger. In this document* he related that a schooner flying the English flag had chased a coastal schooner into the bay; that the alarm had been given that she was a British privateer; that he had at once called out the troops; and that, expecting an attack, he had ordered the women and children to retire to the interior, and had given orders for cattle and sheep to be driven into the woods! "Happily," he proceeded, "all these precautions, dictated by circumstances, proved to be unnecessary." (* Decaen Papers Volume 84.) The English captain had explained to him that he had merely followed the coastal boat because he had no pilot, and wished to enter the bay to solicit succour; "adding that he did not know of the war, and consequently had no idea that he would spread alarm by following it.

Later in the afternoon Dunienville returned to the Cumberland with the district commandant, Etienne Bolger, and an interpreter. The passport was again examined, when Bolger pointed out that it was not granted to the Cumberland but to the Investigator, and that the matter must be dealt with by the Governor personally. At first he desired to send the passport to him, but Flinders objected to allowing it to leave his possession, as it constituted his only guarantee of protection from the French authorities. Then it was arranged that he should travel overland to Port Louis, while Aken took round the ship. But finally Bolger allowed Flinders to sail round in the Cumberland, under the guidance of a pilot. He was hospitably entertained at dinner by Major Dunienville, who invited a number of ladies and gentlemen to meet him; and on the morning of December 16th he sailed, with the major on board, for Port Louis, where he was to confront General Decaen.

The character and position of the Captain-General of Ile-de-France are so important in regard to the remainder of Flinders' life, that it will be desirable to devote a chapter to some account of him.
