The French section listed SS Gallia + Cantatrice; I've deleted Cantatrice as .a) it was a separate incident unrelated to the Gallia sinking, and .b) because the source given (Uboat.net's Cantatrice page) has the sinking on a different day.
The Ottoman section listed Barbarossa Hayreddin + Berk-I-Satvet; again I've deleted Berk-i-Satvet as she wasn't sunk then (or at all, in fact). OTOH I've added a footnote about the steamer Gul Djemal; that may possibly have been a bigger disaster than the Barbarossa Hayreddin was. Xyl 54 (talk) 22:48, 3 January 2018 (UTC)[reply]
@Esemono:: No, there was only one ship by that name, though she was classed variously as a torpedo cruiser or as a torpedo gunboat. The Times article quoted only claims Berk-i-Satvet was sunk by “a British submarine”; another article on the same day ("Two submarines in the Dardanelles") describes Berk-i-Satvet as "built by Krupps in 1906" and gives the same information we have here. But the Berk-i-Satvet article is clear, she was mined in the Black Sea in January 1915 and wasn't back in service until April 1918. OTOH her sister ship Peyk-i Şevket was fired on (and missed) by E12 on 22 June, and again (hit and damaged) on 6 August by E11, which may account for the Times story. There is also a Times account of a Peyk-i Şevket class gunboat being hit in May ("Exploits of E14"), which is attributed here and here to AE2, and here to E14, but that just seems to have been optimistic reporting. I hope that helps, Xyl 54 (talk) 23:38, 6 January 2018 (UTC)[reply]
