Surcouf

Hi again,
I think you will find she was rammed by a merchantman who realized she was sinking ships in the convoy she was escorting. that's why Wikipedia has her as a renegade. Several classes of boats were very slow to dive, the British K boats for instance with their masts and funnels to be taken down before diving. They were regarded as adjuncts to the fleet rather than the hidden silent hunters we are used to.
