The company on board Le Geographe were as excited about the ship sailing eastward, as were the Investigator's men when the reported white rock ahead proved to be the sails of another vessel. The French crew were in a distressingly sick condition. Scurvy had played havoc among them, much of the ship's meat was worm-eaten and stinking, and a large number of the crew were incapacitated. On the morning of April 8th some of Baudin's people had been engaged in harpooning dolphins. They were desperately in need of fresh food, and a shoal of these rapid fish, appearing and playing around the prow, appeared to them "like a gift from heaven." Nine large dolphins had been caught, giving a happy promise of enough meat to last a day or two, when the man at the masthead reported that there was a sail in sight. At first Baudin was of opinion that the ship ahead was Le Naturaliste, rejoining company after a month's separation. But as the distance between the two ships diminished, and the Investigator ran up her ensign, her nationality was perceived, and Baudin hoisted the tricolour.

The situation of the Investigator when she hove to was in 35 degrees 40 minutes south and 138 degrees 58 minutes east. The time was half-past five o'clock in the evening; the position about five miles south-west of the nearest bit of coast, in what Flinders called Encounter Bay, in commemoration of the event. Le Geographe passed the English ship with a free wind, and as she did so Flinders hailed her, enquiring "Are you Captain Baudin?" "It is he," was the response. Flinders thereupon called out that he was very glad to meet the French explorer, and Baudin responded in cordial terms, without, however, knowing whom he was addressing. Still the wariness of the English captain was not to be lulled; he records, "we veered round as Le Geographe was passing, so as to keep our broadside to her, lest the flag of truce should be a deception." But being now satisfied of her good faith, Flinders brought his ship to the wind on the opposite tack, had a boat hoisted out, and prepared to go on board the French vessel.

As Flinders did not speak French, he took with him Robert Brown, who was an accomplished French scholar. On board Le Geographe they were received by an officer, who indicated Baudin, and the three passed into the captain's cabin.

It is curious that Baudin, in his letter to the Minister of Marine, makes no reference to the presence of Brown at this interview, and at a second which occurred on the following morning. He speaks of inviting Flinders to enter his cabin, and proceeds to allude to the conversation which followed when they were "alone" ("nous trouvant seul"). But Flinders' statement, "as I did not understand French, Mr. Brown, the naturalist, went with me in the boat; we were received by an officer who pointed out the commander, and by him were conducted into the cabin," can have no other meaning than that Brown was present. He also says, further on in his narrative, "no person was present at our conversations except Mr. Brown, and they were mostly carried on in English, which the captain spoke so as to be understood." It may be that Baudin regarded Brown merely as an interpreter, but certainly his presence was a fact.

In the cabin Flinders produced his passport from the French Government, and asked to see Baudin's from the Admiralty. Baudin found the document and handed it to his visitor, but did not wish to see the passport carried by Flinders. He put it aside without inspection.

The conversation then turned upon the two voyages. Flinders explained that he had left England about eight months after the departure of the French ships, and that he was bound for Port Jackson. Baudin related the course of his voyage, mentioning his work in Van Diemen's Land, his passage through Bass Strait, and his run along the coast of what is now the State of Victoria, where he had not found "any river, inlet or other shelter which afforded anchorage." Flinders enquired about a large island said to lie in the western entrance to Bass Strait (that is, King Island), but Baudin said he had not seen it, and seemed to doubt whether it existed. Baudin observed in his letter that Flinders appeared to be pleased with this reply, "doubtless in the hope of being able to make the discovery himself."

Baudin was very critical about an English chart of Bass Strait, published in 1800. He found fault with the representation of the north side, but commended the drawing of the south side, and of the neighbouring islands. Flinders pointed to a note upon the chart, explaining that it was prepared from material furnished by George Bass, who had merely traversed the coast in a small open boat, and had had no good means of fixing the latitude and longitude; but he added that a rectified chart had since been published, and offered, if Baudin would remain in the neighbourhood during the night, to visit Le Geographe again in the morning, and bring with him a copy of this improved drawing, with a memorandum on the navigation of the strait. He was alluding to his own small quarto book of Observations, published before he left England, as related in Chapter 12. Baudin accepted the offer with pleasure, and the two ships lay near together during the night.

The story of the interviews, as related by the two captains, is not in agreement on several points, and the differences are not a little curious. Baudin states that he knew Flinders at the very beginning of the first interview, on April 8th: "Mr. Flinders, who commanded the ship, presented himself, and as soon as I learnt his name I had no doubt that he, like ourselves, was occupied with the exploration of the south coast of New Holland." But Flinders affirms that Baudin did not learn his name until the end of the second interview on April 9th: "At parting...on my asking the name of the captain of Le Naturaliste he bethought himself to ask mine; and finding it to be the same as the author of the chart which he had been criticising, expressed not a little surprise, but had the politeness to congratulate himself on meeting me." There may well have been some misunderstanding between the two captains, especially as Flinders did not speak French and Baudin only spoke English "so as to be understood," which, as experience teaches, usually means so as to be misunderstood. It is not very likely that Baudin was unaware of the name of the English captain until the end of the second meeting. While the interview of April 8th was taking place in the cabin, Flinders' boatmen were questioned by some of Le Geographe's company who could speak English, and Peron tells us that the men related the story of the Investigator's voyage.* (* Peron, Voyage de Decouvertes 1 323. Flinders also said that "some of his officers learnt from my boat's crew that our object was also discovery.") It is difficult to believe that Flinders' name would not be ascertained in this manner; equally difficult to believe that Captain Baudin would sustain two interviews with the commander of another ship without knowing to whom he was talking. In fact, Baudin had the name of Flinders before him on the Bass Strait chart which he had been criticising. It was a chart copied in Paris from an English print, and was inscribed as "levee par Flinders." Baudin in his letter to the Minister observed that he pointed out to Flinders errors in the chart "that he had given us." Flinders was of opinion that Baudin criticised the chart without knowing that he was the author of it. Baudin may have been surprised at first to learn that the Captain Flinders with whom he was conversing was the same as he whose name appeared on the chart; but his own statement that he knew the name at the first interview appears credible.

Again, Baudin was of opinion that at the first interview Flinders was "reserved"; whilst Flinders, on the other hand, was surprised that Baudin "made no enquiries concerning my business on this unknown coast, but as he seemed more desirous of communicating information I was happy to receive it." Reading the two narratives together, it is not apparent either that Flinders wished to be reserved or that Baudin lacked curiosity as to what the Investigator had been doing. The probable explanation is that the two men were not understanding each other perfectly.

At half-past six o'clock on the morning of April 9th Flinders again visited Le Geographe, where he breakfasted with Baudin.* (* Flinders does not mention this circumstance; but as he boarded Le Geographe at 6.30 in the morning and did not return to the Investigator till 8.30, Baudin's statement is not doubtful.) On this occasion they talked freely about their respective voyages, and, said the French commodore, "he appeared to me to have been happier than we were in the discoveries he had made." Flinders pointed out Cape Jervis, which was in sight, related the discovery of Spencer's and St. Vincent's Gulfs, and described Kangaroo Island, with its abundance of fresh food and water. He handed to Baudin a copy of his little book on Bass Strait and its accompanying chart, related the story of the loss of John Thistle and his boat's crew, and listened to an account which his host gave of a supposed loss of one of his own boats with a number of men on the east coast of Van Diemen's Land. Baudin intimated that it was likely that Flinders, in sailing east, would fall in with the missing Naturaliste, and he requested that, should this occur, the captain of that ship might be informed that Baudin intended to sail to Port Jackson as soon as the bad winter weather set in. Flinders himself had invited Baudin to sail to Sydney to refresh, mentioning that he would be able to obtain whatever assistance he required there. The interview was thoroughly cordial, and the two captains parted with mutual expressions of goodwill. Flinders and Brown returned to the Investigator at half-past eight o'clock.
