- Cook’s competence earns him promotions and sets the stage for his storied naval career:
  - “It’s the next step in what will become an illustrious career in the Royal Navy, one that will culminate with Cook leading a voyage of discovery to the other side of the world and raising the British flag over an entire continent on August 22, 1770.” (03:23, Lindsay Graham)
Skill in Surveying & Cartography (05:33–09:57)
- By 1758, Cook is recognized for his cartography skills while mapping the St. Lawrence River for the British fleet, contributing to the successful attack on Quebec and solidifying his value to the navy.
- For nearly a decade, he meticulously charts the rugged coastlines of Nova Scotia and Newfoundland.
- Cook’s scientific pursuits are highlighted when he records a solar eclipse, impressing British scientists with his accuracy.

The Pacific Expedition & Scientific Mission

The Great Pacific Journey (09:57–11:30)
- In 1768, Cook is chosen to lead an expedition to the Pacific, tasked with observing the rare transit of Venus—crucial for astronomical research and measuring Earth’s distance from the Sun.
- The expedition forges an early link between exploration, imperial ambition, and emerging scientific inquiry.
Turning to Terra Australis (11:37–13:05)
- After the successful transit observation in Tahiti, Cook opens secret orders: he is to search for the mythical “Terra Australis”—a hypothesized vast southern continent.
- The search takes Cook and the crew to New Zealand, but after circumnavigation, he realizes it is not the great southern landmass sought by Europe.
Discovery of New South Wales (13:05–14:18)
- Sailing westward, Cook’s ship finally sights the east coast of Australia in 1770—a land unknown to Europeans.
- Cook names this region “New South Wales,” comparing its landscape to parts of England.

First Encounters and Challenges

Initial Contact with Aboriginal Peoples (14:18–15:48)
- Cook’s landing is met with resistance from local Aboriginal inhabitants; warning shots and a brief violent incident make clear that the land is neither empty nor welcoming.
- “Cook fires a warning shot over their heads, but they respond with a barrage of stones and darts. Only when one of the Aboriginal men is clipped by a shot from Cook’s musket do they retreat into the forest beyond the beach.” (14:44, Lindsay Graham)
Botanical Discoveries and the Great Barrier Reef (15:48–17:24)
- The crew marvels at the unique wildlife and flora, leading Cook to name their initial landing place “Botany Bay.”
- The journey nearly ends in disaster when the Endeavour runs aground on the Great Barrier Reef, forcing the crew to dump vital supplies and cannons to save the ship.
- After repairs (during which Cook encounters his first kangaroo), the voyage continues northward.

The Claiming of Australia

The Ceremony on Possession Island (17:24–18:40)
- On August 22, 1770, Cook conducts a brief but momentous ceremony on what he names “Possession Island,” raising the British flag and claiming the east coast of Australia for King George III.
- “Cook attaches the British flag to a pole that’s been dug into the grassy soil. He says a few words, claiming the island and its surroundings on behalf of King George III.” (17:47, Lindsay Graham)

Legacy and Lasting Consequences

Return to Britain and Aftermath (18:40–19:25)
- Cook returns to England after nearly a year; his detailed charts enable further exploration and colonization.
- His maps of the Great Barrier Reef are so accurate they’re still in use over a century later.
- “But British colonial expansion in Australia will come at a steep cost to the communities who already live there. The Aboriginal inhabitants will face violence and assault on their culture as the British newcomers seize more and more of their land.” (19:10, Lindsay Graham)
Cook’s Fate (19:25–19:55)
- Cook sails on further Pacific expeditions, ultimately dying in Hawaii in 1779.
- Despite his death, Cook is remembered in Britain as a pioneering explorer—though his actions remain inseparable from the darker legacies of colonial expansion.

For the past year, Britain has been at war with France. It's not unusual for these two powers to be in conflict, but this time the fighting isn't just taking place in Europe. The theater of war has expanded to British and French colonies in North America, and over the last few weeks, HMS Eagle has been part of a British fleet patrolling the Atlantic Ocean. And now the ships have sighted the French warship Esperance, nearing the end of a transatlantic crossing. The nearest British ships to the Esperance open fire, but the Eagle is still too far away to use its cannons. So at a signal from his captain, Cook turns to a sailor and tells him to unfurl another sail in an attempt to close the gap. As master's mate, Cook is one of the officers on board the Eagle, and it's his job to relay the captain's orders to the crew. Soon, Cook feels the ship accelerate as the extra sail catches wind. But by the time the Eagle comes alongside the Esperance, flames are already consuming the French warship's hull. The other British ships have crippled the enemy vessel, so Cook watches as French sailors abandon ship, jumping off the side and into the water. Without waiting for his captain's orders, Cook hurriedly tells the sailors manning the wheel to steer away. There's no greater danger on the high seas than a warship on fire, and if the Esperance's gunpowder store explodes, it might take the Eagle down with it. A few minutes later, the Esperance sinks beneath the waves. It's the second victory in as many months for the HMS Eagle and the British fleet, and soon several of its officers will be rewarded with promotions. Among them will be Master's Mate James Cook. It's the next step in what will become an illustrious career in the Royal Navy, one that will culminate with Cook leading a voyage of discovery to the other side of the world and raising the British flag over an entire continent on August 22, 1770.

From Noiser and Airship I'm Lindsey Graham and this is History. Daily history is made every day on this podcast. Every day we tell the true stories of the people and events that shaped our world. Today is August 22, 1770. Captain Cook claims Australia. It's nearly midnight on July 23, 1758, in the Gulf of St. Lawrence off the coast of Canada, two years after the sinking of the French warship Esperance. James Cook calls to his fellow crew members on night duty and points into the dark distance. Cook is now a 29 year old master on board HMS Pembroke and ahead he can see the fortress of Louisbourg illuminated by orange flickering lights that can mean only one the French citadel is on fire during the Two years that have passed since his first victories with the Royal Navy, Cook has continued to rise through the ranks. He's had his first taste of command with smaller vessels and passed exams that entitle him to greater responsibility aboard bigger ships. Cook's latest posting has sent him here to the Gulf of St. Lawrence. And for the last month, HMS Pembroke has been part of a fleet besieging the fortress of Louisbourg, a key stronghold that guards the entrance to the St. Lawrence River. Now, a lucky shot from a British gun has sparked a blaze in the French fortress. Cook lifts a telescope to his eye to get a closer look. And all through the night, Cook watches tiny figures silhouetted against the inferno as the French garrison frantically fights the blaze. By morning, though, the fortress is a smoking wreck, and a few days later, its commander surrenders to the British. The ships of the Royal Navy are now free to sail into the St. Lawrence River. But the British don't rush in. Since this is French land, the British don't have accurate charts of the region. So to minimize the risk of losing valuable warships to unknown obstacles or shallow waters, Cook is assigned the task of mapping the river. Although he must often work under cover of darkness to avoid French attack, he soon displays a talent for surveying and cartography. Cook takes accurate soundings and plots a safe course along the waterway. And thanks to his charts, British ships are soon able to navigate the length of the St. Lawrence river, allowing British forces to carry out a surprise attack on the French city of Quebec. This capture of Quebec ends the fighting between Britain and France in North America. But Cook's newfound surveying skills means he's still in demand. His next orders are to map the jagged coastlines of Nova Scotia and Newfoundland. And for almost a decade, Cook undertakes several voyages that painstakingly pick their way north, taking precise recordings and drawing up new charts. And it's not just the coastline that captures cook's attention. In August 1766, he pauses his mapmaking for a few days to carry out a different form of observation. Cook knows that a solar eclipse is due, so he drops anchor off an uninhabited island. The fog that has lingered for days clears just in time for Cook to witness the eclipse, and he records the spectacular event in as much detail as possible. His notes are passed on to Britain's top scientists, who are impressed with his work. So when Cook returns to London in late 1767, the British Admiralty soon gives a new job to their top surveyor, James Cook. They want a ship to sail to the Pacific Ocean ahead of a rare astronomical event. The planet Venus transitioning across the Sun. Among the passengers on the ship will be two astronomers to take measurements of the once in a century occasion. And the more recordings they take, the more accurately they'll believe they'll be able to work out Earth's distance from the Sun. Cook is the obvious candidate to lead the Pacific expedition, so he's promoted to lieutenant and given command of the HMS Endeavour. On August 26, 1768, Cook sets sail with almost 100 crew astronomers and other scientists on board. Eight months later, the Endeavour drops anchor at Tahiti, one of the few islands in the Pacific with an accurately plotted longitude and latitude. Cook has arrived well in advance of the transit of Venus, and his crew spends the next two months building an observatory. Cook keeps his fingers crossed for good weather, and on the day of the transit, they're blessed with clear skies. After the observatory is dismantled and all the equipment packed away, the Endeavor is soon ready for the high seas again. The ship is more than 9,000 miles from home, but before it returns to England, it will journey even further. Over the next two years, Lieutenant Cook will guide the Endeavor off the edge of the map and go places that no British person has ever gone before. History Daily is sponsored by indeed.
