http://www.bookdepository.co.uk/6th-Heavy-Anti-Aircraft-Regiment-Royal-Artillery-Patrick-Walker/9780956219046The only connection I have to the book is through my late mother who as a young girl lived on Penn Common near to where the regiment was stationed for a time during the war. The author asked if she could remember anything about that time.
The book does contain a long list of soldier's names who served with the regiment, their medals and honours. Also a Roll of Honour for those who did not survive.
They do seem a very unlucky regiment, I expect it was the same for most at that time.
I hope this helps someone.
I should say other Royal Artillery books are available. (I don't think there are any on the 6th HAA though)
