London Submarine Protocol
The London Submarine Protocol of November 6, 1936 is an international agreement on naval law . This makes it clear that submarines must comply with the same rules of international law as surface ships with regard to merchant ships.
In particular, both submarines and other warships may only sink a merchant ship when passengers, crew and papers have been brought to a safe place. Lifeboats or dinghies are expressly not considered a safe place if there is no land or another vehicle nearby.
