Musket, that "historical" work written by Alan Clarke entitled "Donkeys", perhaps you should read some of the peer reviews it got by his "fellow historians" of the day. Then remember two things about that book:

1: That it restricts itself to the year of 1915 and the conduct of those in command in 1915 - The Commander of the BEF throughout 1915 was Field Marshal Sir John French NOT Douglas Haig - Clarke's book does not cover the entire war, or any subsequent commanders.

2: That to sell the book Clarke made up the "Lions led by donkeys" quip attributing it to two senior German Staff Officers.

Tell me Musket, honestly, how credible do you rate or think a historian is who just makes stuff up?
