I only found out today that Charles Whiting, a prolific writer of 'trashy' novels and mass-market military history, in spite of being a trained academic, had died in July, while I was in the United States. There's a good memory of him by Steve Newman.
Whiting was very much a product of his time. It's difficult to imagine today the amount of war books one could find in the 1970s, and every other boy I met in 1970s Britain seemed to be acquainted with some of them. You'll find the long list of his titles at Bear Alley, a blog. It's worth noting how many of them were published by Leo Cooper or one of the publishers associated with Anthony Cheetham, reminding us that once you get in with the right people, life is a lot easier.
