Hi Guys

HMT Balfour sank following a collision in the English Channel off Sovereign Lightship on 13 May 1918.
The Balfour was escorting the steamship Nidd to Dieppe. The Nidd allegedly ran over (collided with) a U-boat, which then surfaced behind the Nidd. The Nidd went
full steam ahead and opened up with stern gun. Reportedly hitting the U-boat.
The Balfour turned to attack the U-boat and cut across the bow of the Nidd, was
accidentally rammed and sank.

Royal Navy Trawlers by G. Toghill says the Balfour sank following a collision with the lightship, but Shipwreck Index Of the British Isles says sank after a collision OFF the lightship?

Does anyone know if a U-boat was invlved and which one please?
UC 71 seems to have been operating at least some in the eastern English Channel at the time, but I/we don't have access to her KTB ?

Cheers Ron
