The Mary Rose was a warship that sank in full view of the enemy - Apparently.
The Mary Rose, a 16th-century warship, sank in the Solent Strait off the coast of England on July 19, 1545, while engaged in a naval battle against France. King Henry VIII's flagship was carrying over 500 soldiers, but only 30 survived the disaster. The ship's stern was above water for about 19 minutes, allowing the French to watch as it went down. The wreck was discovered in 1971 and excavated, providing valuable insights into shipbuilding techniques and naval warfare during the Tudor period.
