Here is a review of Robert Lansing's (1864 – 1928; Secretary of State: 1915-1920) 1922 book, Big Four, and Others of the Peace Conference. In this book (Lansing's follow-up to his earlier volume, The Peace Negotiations: A Personal Narrative) the author
"shows us Clemenceau dominating the conference by sheer force of mind; Wilson outmaneuvered; Lloyd George clever, alert, but not very deep; and Orlando precise and lawyerlike. This book confirms the popular belief that the general scheme of the treaty was worked out by the British and French delegations without material aid from the Americans. As a consequence, the American delegation lost prestige."
