Battle of Maldon: The English, led by Byrhtnoth, Ealdorman of Essex, are defeated by a band of inland-raiding Vikings near Maldon, Essex.
In 991, English forces under Ealdorman Byrhtnoth were defeated by Viking raiders at the Battle of Maldon in Essex.
The Battle of Maldon saw local English levies attempt to repel a Viking landing party near the River Blackwater. Despite initial valour and fortified positions, the English were outmaneuvered and overwhelmed by the Norse warriors. Byrhtnoth himself fell in combat, and his leadership became immortalized in the Old English poem "The Battle of Maldon". The defeat exposed the vulnerability of the English kingdoms to seaborne raids and led to increased tribute payments known as Danegeld. The battle remains a symbol of early medieval heroism and the turbulent Anglo-Saxon era.

Jaume Ferrer sets out from Mallorca for the "River of Gold", the Senegal River.
In 1346, Mallorcan navigator Jaume Ferrer embarked on a voyage to find the legendary 'River of Gold', believed to be the Senegal River.
Jaume Ferrer's expedition aimed to establish a maritime route from the Mediterranean to West Africa's gold-rich regions. Sailing from Mallorca in a single small ship, he ventured beyond the familiar waters of the Atlantic coast. Although the outcome of his journey is unknown, his attempt prefigured later Portuguese exploration along Africa's shores. Ferrer's voyage reflects early European commercial ambition and curiosity about sub-Saharan Africa. It stands as a precursor to the major Age of Discovery expeditions of the 15th and 16th centuries.

On August 10, 1519, Ferdinand Magellan departed Seville with five ships on a pioneering voyage to circumnavigate the Earth.
Magellan's fleet set sail westward in search of a direct route to the Spice Islands, traversing the Atlantic and discovering the strait that now bears his name.

Magellan was killed in a skirmish in the Philippines, but command passed to Juan Sebastián Elcano. Under Elcano's leadership, the remaining vessel completed the first circumnavigation of the globe in 1522. This monumental achievement demonstrated the true scale of the planet and inaugurated a new era of global maritime exploration.

The Swedish warship Vasa sinks on her maiden voyage off Stockholm.
In 1628, the Swedish warship Vasa tragically sank on her maiden voyage from Stockholm due to instability in her design.
Built for King Gustavus Adolphus, the Vasa was one of the most heavily armed warships of the era.
On August 10, 1628, she sailed from Stockholm harbor but capsized and sank after traveling just over a kilometer.
Design flaws and inadequate ballast caused the ship to list dangerously.
The wreck lay submerged for over 300 years before being salvaged in 1961 nearly intact.
Today, the Vasa Museum in Stockholm displays this remarkable vessel and its richly decorated hull.
