On this day 251 years ago, on March 16, 1774 (February 5, 1774 lunar calendar), the British naval navigator Matthew Flinders was born. Matthew Flinders (March 16, 1774 - July 19, 1814) was one of the most successful of many navigators and cartographers until the early 19th century; during his professional career of just over 20 years, he was with another captain, William? Bly (the captain of the famous remake movie Rebel Ship) sailed around Australia together, and named after the many newly discovered areas in Australia that he was encouraged to do, and was rescued from shipwrecks. The only disaster was to imprison him on espionage charges. He was guided to shore by a compass on a wooden ship. He was the first seeder of "Exploring Unknown Australia". He overcame the achievement, verification and correction of data with his steely will and was published in "Hailing the Australian Territory". In 1801, the British Navy ordered him to explore the "Great Australian Bight" and many parts of the bay; in July of that year, he led an expedition as far away as England, arrived at Cape Levine in Australia on December 6, and continued westward to "Fowlers Bay" on January 28, 1802. On April 8, 1802, during the eastbound voyage of the fleet, Matthew Flindas encountered the French explorer Nicholas Baudin. On his way westward on the ship Le Géographe, they were both supported by their own country to explore the unknown southern coastline of Australia. The two also exchanged academic details to study many precious discoveries. Finally, the two exploration teams went to Sydney to replenish supplies. Later, Flindas named the place they first met as Meeting Bay (not Japan's Meeting Bay). The meeting of the two explorers in "Meeting Bay" this time marked that the main colonial countries of the European continent had mapped the entire Australian coastline, which was of great significance. In June 1803, the survey ship Investigator had to be repaired due to severe damage to its shell, so Flintas was forced to give up exploring the northern coastline of Australia. He returned to Sydney along the west coast to officially end his maiden voyage around Australia. Flintas wanted to continue the North Australian survey on board the British ten-gun battleship Whale, but was unable to achieve it when the ship hit the reef and was shipwrecked on the Great Barrier Reef. At this time, he did something that made him want to do something: he ventured with a few sailors to sail small sails 700 miles across uncharted open seas to return to Sydney, and planned to summon a ship to WreckReef to rescue his black crew. Flintas then tried to take the Cumberland back to England, but on December 17, 1803, he was forced to dock in Mauritius for ship repair. Flintas did not know that Britain was fighting France again at this time. General DeCaen, the French governor of Mauritius, arrested and imprisoned him as a "prisoner of war". Flintas wrote to Sir Joseph Banks for help. Joseph Banks informed the French authorities that he was aware of Flintas's academic status. France allowed Flintas to be released, but General DeCaen refused to let him go because of the misunderstanding that the Flintas ship went to Mauritius to investigate the French military situation. Due to the misunderstanding and war, he was imprisoned in France for six and a half years until 1810. Flintas finally returned to England in October 1810, but after six and a half years in prison, his health was much worse than before. He died the day after he published the results of his exploration in Australia AVoyagetoTerraAustralis published on July 18, 1814, at the age of 40. Recommended reason: The first British naval navigator to circle Australia.
