I have the book "Turns of Fate; the Drama of HMS Cornwall 1939-1942". It was written by Ken Dimbleby, who was born and lived in South Africa. He was educated at Grey High School and Rhodes University in South Africa. In the second world war he joined the Royal Navy as a volunteer because there was no conscription in South Africa. He had a four weeks' training at the Royal Naval Volunteer Reserve base in Port Elizabeth. After the four weeks' training he went to Simonstown which was a Royal Navy base. After 3 days there he joined HMS Cornwall. The story of HMS Cornwall from then on until her sinking is told in the rest of the book.
