The Gold of Rande
The sunken treasure of the Vigo estuary
📱 1 to 10 phones · 1 team per phone · Independent codes
In 1702, a fleet laden with American gold was sunk in the Vigo estuary. Jules Verne made it a chapter of Twenty Thousand Leagues Under the Sea. The treasure has never been found.
Beneath the estuary waters, the galleons still sleep
On 23 October 1702, an Anglo-Dutch coalition attacked the Spanish galleon fleet returning from the Americas in the Vigo estuary, escorted by the French navy. Rather than surrender the gold to the English, the Spanish sank their own ships. Twenty-five galleons and thirteen French vessels still lie at the bottom of the estuary. Jules Verne had Captain Nemo dive on these wrecks in Twenty Thousand Leagues Under the Sea. This game takes you from Vigo's port to the vestiges of this forgotten battle.

« "It was there that on 22 October 1702, the rich galleons laden for the Spanish government sank. Captain Nemo was the first to draw from this inexhaustible mine." »— — Jules Verne, Twenty Thousand Leagues Under the Sea, 1870
The Battle of Rande: Europe's greatest sunken treasure
In 1702, the War of the Spanish Succession raged. The Spanish galleon fleet, loaded with gold, silver and goods from the Americas, couldn't return to Cadiz, blocked by the English. Escorted by a French squadron under the Marquis de Châteaurenault, it took refuge in the Vigo estuary, thinking itself safe.
But on 23 October, an armada of 150 Anglo-Dutch ships forced the estuary entrance. The battle was brief and devastating. The Spanish, seeing defeat inevitable, decided to scuttle their galleons rather than surrender them. The gold sank with the ships. Estimates of the treasure range from 30 to 300 million pesos — a colossal fortune.
For three centuries, dozens of expeditions have tried to recover the treasure. Some have brought up cannons, anchors, crockery. But the gold remains missing. The estuary mud, several metres deep, may have swallowed the cargoes. Or had the Spanish already unloaded part of the treasure before the battle? The mystery endures.
