"The President and the Prime Minister had discussed the matter repeatedly, and both seemingly favored Marshall for the command. King felt that Marshall too wanted it, although he never said so. It was only natural, in King's view, that he should want it, as it was the most enviable duty that could come to any military man during the war. Nevertheless King felt strongly that Marshall was indispensable as a member of the Joint and Combined Chiefs of Staff, however desirable he might be as Supreme Commander. During the Quebec Conference when Secretary Knox, who had by exception been present for a couple of days, King had insisted forcibly that Marshall could not be spared, as he was a key-man, both in the United States and in the Allied organizations, and it seemed a poor idea to swap horses in midstream. Secretary Knox had countered that no one remembered the name of the Chief of Staff of the Army during World War I, whereas everyone knew General Pershing. King had pointed out, however, that World War II was very different from World War I, since now there were many oceans and many continents to be considered, against the single Atlantic Ocean and the single continent of Europe in the previous war."
