Yes it's interesting the way that Titanic has grabbed attention and emotion. Just today I was reading about the loss of HMT Lancastrian in 1940; and I have been privileged to know a member of the HMS Hood Association (he was transferred out of Hood before she was lost).
I have read about Cressy, perhaps prompted by discovering a casualty from HMS Aboukir, also sunk in the same action; and then I have also read about the loss of HMS Monmouth, lost with all hands at Coronel. I found the service record of the man lost with Monmouth poignant: just two words, "Promising, active," and then the Naval abbreviation DD [discharged dead] to describe his entire career. And I discovered another tragedy, this time not the result of enemy action: HMS Vanguard exploded in Scapa Flow in 1917, killing over 800; there were two survivors.
And how will the Lusitania's loss be viewed on that centenary in five years' time?
