Guest,henryp I would suggest that you look up the meaning of "To coin" something as in "To coin a phrase".

Alan Clark, did coin the phrase {something you say before using an expression that has been used too much} "Lions led by donkeys" to give title to and to denigrate those he mentions in his book.

He did invent the story that the phrase came from a discussion between to very senior German Officers. He did that and spread that deliberate lie in order to reinforce the message he tried to peddle in his book.

I personally do not think much of any historian who just invents stuff and then just sits back quietly collecting coin while his rather poor history is then used and abused until the misconception is reached where people think that the book covers the entire period of the Great War instead of only one year of it.

I think that you will find elsewhere I did turn up one possible origin of the phrase:

"The phrase Lions Led by Donkeys was used as a title for a book published in 1927 by Captain P.A. Thompson. The subtitle of this book was "Showing how victory in the Great War was achieved by those who made the fewest mistakes."

Now then if the Allies were victorious in the Great War would that make them the ones who made the fewest mistakes? If so then they could not possibly be the donkeys being referred to in the title could they?

Yes Musket "sought to rescue" due to complete and utter clots such as yourself relying on fiction and your own imagination to provide you with information relating to historical events.
