It is not a tale ofheroics and "derring-do", which is what a publisher needs for a proper "War Book" to sell
It's very unfortunate what you say is true in the commercial world
Danny of publishing, but there would be a market, how large is difficult to tell.
A lad from our area flew Hurricanes in the Western Desert and was shot down over Sarajevo later in the war while flying a Spitfire. Became POW and liberated by the Russian and spent best part of a year in their custody before repatriation and demobbing.
Came home to return to his previous life of farming. Died an early death, a result of dysentery after effects suffered in the Western Desert. Used to foul the bed every night his wife wrote. Pilots used to fly just wearing shorts, canopy open due heat, and cockpit would be covered in faeces on return, such was their state. A snippet you wouldn't read in a commercial venture I dare say.
His wife wrote and self published a little compendium of paperback size. No great tales of daring do or heroics in the usually accepted sense, just the story of a bloke like yourself who answered the call, and performed his duty as was asked of him. You do have a story to tell, as elicited in your thread, and one which we doff our caps to. You do have a flair for words
Danny, and their use. Every time an individual passes a library burns down.
