When Churchill's many fanciful strategic ideas collided with sound military strategy it was only Brooke on the Chiefs of Staff Committee who was able to stand up to the Prime Minister. Churchill said about Brooke: "When I thump the table and push my face towards him what does he do? Thumps the table harder and glares back at me. I know these Brookes – stiff-necked Ulstermen and there's no one worse to deal with than that!" It has been claimed that part of Churchill's greatness was that he appointed Brooke as CIGS and kept him for the whole war.
