It is with deep sadness, yet immense pride, that we, his family, announce the 'crossing of the bar' of D H
The Slow Death of a Submarine explores in minute detail a more rounded picture of what really happened before, during and after her tragic loss. In doing so Tony Booths book also takes a fresh look at culpability and explores some of the alleged conspiracy theories that surrounded her demise.
The result is the first definitive account what happened to HMS Thetis and her men a fitting tribute, as the seventieth anniversary of her loss will be on 1 June 2009.
