On this day, 12 October 1919, 150 Royal Navy sailors mutinied and broke out of their ships at Port Edgar upon hearing they were being sent to the Baltic to fight against the Russian Revolution. The desertion prevented the First Destroyer Flotilla from departing. Most of the mutineers were arrested and 10 imprisoned: despite the government having pledged that only volunteers would be sent to fight against the Russians.
