Magellan's fleet emerged from its strait into the Pacific Ocean

On this day · 28 November 1520

After a brutal 38-day passage through a frozen southern labyrinth, three battered ships sailed into an ocean so calm it earned a hopeful name.

Verified · EBSCO Research Starters — 'Misinformation effect'

On November 28, 1520, Ferdinand Magellan’s three surviving ships — the Trinidad, Concepción, and Victoria — slipped out of the southern passage at the tip of South America and into open water, becoming the first known European expedition to reach the Pacific from the Atlantic.

The crossing had not been gentle. The fleet had probed the channel since late October, and the transit of the roughly 350-mile strait — later named for Magellan — took about 38 days of scouting blind inlets, fighting cold, and weathering a mutiny and a desertion. One ship had already turned back for Spain.

When open ocean finally appeared at the far end, Magellan is said to have wept.

The water beyond seemed eerily tranquil after the strait’s violence, and the expedition christened it the Mar Pacífico — the “peaceful sea.” The calm was deceptive. Ahead lay a crossing of months with dwindling food, and Magellan himself would die in the Philippines before the voyage’s end.
