I've only just caught up (two years late) with reading this excellent book on the sinking of HMS Aboukir, Hogue and Cressy on 22 September 1914 by a single German U-boat.
Stuart Heaver's 'The Coal Black Sea' is a vivid account of the disaster, with plenty of naval detail (the author was a navy officer himself) to engross those interested in the sea, and a full account of Winston Churchill's role and the political spin that followed the losses.
Not to be missed by anybody interested in the First World War.
Klaudie Bartelink's poignant film about the cruisers, with amazingly beautiful footage of the wrecks, can be seen at
