The sinking of the Lancastria during WWII remains Britain's worst maritime disaster. On 17 June 1940, over 4,000 people died after German bombers hit the ship they were being evacuated on. This previously unknown painting (courtesy of Sky News) shows the WWII attack on the Lancastria. It sank within 25 minutes just a few miles out to sea near the French port of Saint-Nazaire. The death toll was more than the sinking of the Titanic and the Lusitania combined.
