1475, when Edward IV of England agreed not to pursue his claim further. English and later British monarchs continued to use the title of King or Queen of France until 1801. Pale of Calais: Calais had been captured by Edward III in 1347 and English possession was confirmed by the Treaty of Brétigny. It was the only remaining English possession on the Continent after the effective end of the Hundred Years' War in 1453. Calais was recaptured by the French in 1558 and French occupation recognised by the Treaty of Cateau-Cambrésis in 1559. English claims were finally abandoned by the Treaty of Troyes in 1564. Tournai: Tournai was occupied by Henry VIII of England following the Battle of the Spurs in 1513. It was returned to France in 1519 under the terms of the Treaty of London. Le Havre: English troops occupied Le Havre under the Treaty of Hampton Court in 1562. The town was reconquered by the French the following year. Cautionary Towns: English possession of Flushing and Brill was confirmed by the Treaty of Nonsuch in 1585. The towns were sold to the Dutch Republic in 1616. Dunkirk: French and English forces captured Dunkirk from the Spanish in 1658, and the town was granted to England by the Treaty of the Pyrenees the next year. Dunkirk was sold back to France in 1662. Gibraltar: In 1704, Gibraltar was captured for England by an Anglo-Dutch fleet, becoming the country's first European overseas possession since the sale of Dunkirk to France in 1662. The Naval operation was commanded by George Rooke. Gibraltar later became a strategic naval base for the Royal Navy and was officially ceded to Great Britain in 1713. As of today it still remains a British possession. Transformation into British Empire The Treaty of Union of 1706, which with effect from 1707 combined England and Scotland into a new sovereign state called Great Britain, provided for the subjects of the new state to "have full freedom and intercourse of trade and navigation to and from any port or place within the said united kingdom and the Dominions and Plantations thereunto belonging". While the Treaty of Union also provided for the winding up of the Scottish African and Indian Company, it made no such provision for the English companies or colonies. In effect, with the Union they became British colonies. List of English possessions which are still British
