"Field Marshal Montgomery, like General Patton, conformed to no type. He deliberately pursued certain eccentricities of behavior, one of which was to separate himself habitually from his staff. He lived in a trailer, surrounded by a few aides. This created difficulties in the staff work that must be performed in timely and effective fashion if any battle is to result in victory. He consistently refused to deal with a staff officer from any headquarters other than his own and, in argument, was persistent up to the point of decision."
