The passenger liner Persia was sunk off Crete, while the passengers were having lunch, on December 30, 1915, by German World War I U-Boat ace Max Valentiner (commanding U-38). The Persia sank in five to ten minutes, killing 343 of the 519 aboard. The sinking was highly controversial, since it broke naval international law, or the "Cruiser Rules", that stated merchant shipping carrying passengers should be given opportunity for the passengers to disembark before combat could commence. A warning shot across the bow should have been given first. Instead, the U-Boat fired a torpedo with no warning. At the time of sinking, Persia was carrying a large quantity of gold and jewels belonging to the Maharaja Jagatjit Singh.
