re: WWII history buffs, is this quote by General Patton true?

From reading some ww2 biographies , a lot of them mention the Americans had a lot more in common with the German people than the Russians or French and maybe even the English. And were surprised as they made their way through Europe, seeing that the Germans were orderly, disciplined, and civilized , not the bloodthirsty devils they were told. And the Russians in particular were the uncivilized savages they were also not expecting. (Obviously this is the rank and file soldiers and civilians, not the Nazi war criminals. )
