According to Samuel Leech, after being captured the crew of "Syren" were taken to the Cape of Good Hope, and after landing at Simonstown, marched to a jail in Cape Town. Here they were held until transferred to England when the war was over. On arriving at Simonstown, other American prisoners were seen to be leaving the jail and being shipped off to Dartmoor. The "Syren" crew met these again in England while waiting for transfer to the United States. Some had been present at 'The Massacre'.
