It appears to me that Devers wanted to cross the Rhine with his group and not just aid Patton in his crossing the Rhine. Plus, I think Devers saw himself as in charge of more of the war fighting than Patton. All 3 of the Generals involved in the arguments should have had better soft interpersonal skills. In some situations it is good to be able to yell and jump up and down on your desk to get things done, but those times are for your lower ranks than you. I certainly set lower ranks straight when I was in the Army. I just don’t think the argument was do to jealousy of Ike.
