The Bounty Saga

HMS Bounty’s Pacific Voyage, 1787–1789

Spithead to the eve of mutiny: 517 days under Lieutenant Bligh’s command — beaten back at Cape Horn, the long road east by the Cape of Good Hope, five months at Tahiti, and 1,015 breadfruit plants bound for the West Indies. Day by day, from Bligh’s own logs.

Bligh’s Open-Boat Voyage, 1789

47 days. 3,618 nautical miles. A 23-foot launch from Tofua to Coupang after the mutiny on HMS Bounty.

The Mutineers’ Voyage, 1789–1790

The Bounty under Fletcher Christian: a fortress raised and abandoned at Tubuai, the split at Tahiti, and the ship’s disappearance toward Pitcairn — told from the journal of James Morrison, boatswain’s mate, who stayed and was captured.

The Age of Discovery

Columbus’s First Voyage, 1492–93

Palos to a Bahamian landfall and back: 225 days, three ships, and the crossing that joined two hemispheres. The false reckoning, the wreck of the Santa María on Christmas Day, the garrison left at La Navidad, and the storm-driven return through the Azores and Lisbon — day by day, from the Journal as Las Casas preserved it.

Magellan’s Circumnavigation, 1519–22

Sanlúcar around the world and home: five ships west to reach the Spice Islands, a mutiny put down in Patagonia, the strait and the first Pacific crossing, Magellan’s death at Mactan — and one ship, the Victoria, closing the first circle around the earth. Day by day, from Pigafetta’s eyewitness account and Albo’s log.

Cook’s First Voyage, 1768–71

Plymouth around the world and home: 1,051 days aboard HMS Endeavour under Lieutenant Cook — to Tahiti for the transit of Venus, south after a continent that wasn’t there, New Zealand circumnavigated, and the whole east coast of New Holland charted and claimed. The reef that nearly ended the voyage, and the Batavia fever that undid a scurvy-free crossing. Day by day, from Cook’s own journal.
