Jim, has Sheffield ever said or written anything that contradicts my views.
No. You said he had, but you just made that up.
That is why there was no quote.

Here are the historians who I have quoted in support of my case.
Richard Holmes, Peter Hart, David Stephenson, Fritz Fischer, Dan Todman, Gary Sheffield, Max Hastings, Malcolm Brown, Stuart Halifax, Catriona Pennel, Margaret MacMillan, Tristram Hunter.
I will add "she" when we learn her name.
She must support me or musket would have given it.

Of course there are more.
Every university has a History dept. but not all write about WW1.

In the ten weeks of this debate, none of you have found one that contradicts me.
I will stop claiming "all" when you find one.
Fair enough?
