In 1543 Henry VIII of England declared war on France and seized Boulogne. In response, Francis I prepared a fleet to invade England. The opposing naval forces met off the English coast on July 19–20, 1545, in a tentative encounter that deterred a French invasion but is chiefly remembered for the sinking of the Mary Rose.
As the French assembled their fleet of 150 sailing ships in Le Havre, joined by 25 galleys brought from the Mediterranean, the English under Admiral John Dudley launched a largely fruitless preemptive strike. His fleet returned to Portsmouth, England’s chief naval base, for essential repairs but was far from ready when the French fleet, carrying an estimated 30,000 soldiers, crossed the Channel to the Sussex coast and then sailed west to the mouth of the Solent, between Portsmouth and the Isle of Wight off the south-central coast of England.
On the fine, still morning of July 19, the French galleys entered the Solent in sight of Henry VIII, who was reviewing his fleet in Portsmouth. The English fleet set sail, taking advantage of a freshening breeze to approach the galleys. One ship, the large but elderly Mary Rose, fired her starboard guns at the galleys and then turned to prepare to fire her port side guns. As she did so, she floundered, either as a result of enemy gunfire or more probably as a result of a sudden gust of wind that caused her to keel over and submerge her open starboard gun ports. As the sea poured in, the ship quickly sank, killing all but 30 of its 415 crew.
The French failed to capitalize on this disaster. Both fleets exchanged long-range cannon fire the next day, and on July 21 several hundred French soldiers went ashore on the Isle of Wight, the last invasive landing by foreign troops in British history. Local militia drove back three attacks, whereupon the French troops returned to their ships, which sailed to Le Havre on July 28. While the English tried to salvage their sunken ship, the French headed home across the Channel.
Raised from the seafloor in 1982, the remains of the Mary Rose, representing about 40 percent of the ship, as well as artifacts from the wreck are housed in the Mary Rose Museum in Portsmouth.
Losses: English, 1 ship of 80; French, no ships of 175.
