I've got a truly wonderful source book - Vol 1. of "The Navy and Defence", by Chatfield. He was 1st Lord of the Admiralty (IIRC) in WW2; this book covers his experiences from joining as an ensign in the 1870s, through to just before WW2. Most famously, he was captain of HMS Lion at the battle of Jutland, and was the one Beatty made his famous comment to.
It's a superb look at the transition of the Royal Navy from wood and sail to steel and steam, and covers the evolution in gunnery indetail (he commanded Whale Island for some years). it's also a fascinating if somewhat gruesome look at the social mores and restrictions. Chatfield himself was socially blessed and led a seemingly charmed life, moving ever upwards up the chain of command.
One of these days I must find Vol 2; I found Vol 1 in a second-hand bookshop for $10 ...
