More selective quoting from Keith A of Hertford.

Not true.
I provided whole paragraphs and linked to the whole article.
I can produce many more examples of him saying the same.

As I said, Dr Gary Sheffield concluded that senior military leaders were both callous and incompetent.

As you lied, actually.
General French has come in for some criticism, but who else?

You say you(?) disagree with Sheffield's conclusions on Haig.
The fact that other historians do agree will make that easier for him to live with!
What is your opinion worth when it is rejected by all the people who actually know anything?
