It might be interestign to review the list of US generalofficers who were relieved of their commands in the early days of WW II, starting with Kasserine Pass.
You might find some earlier than that. The early days around Guadalcanal was not the U.S. Navy's finest hour. For individual ship C.O.'s. I don't know about admirals.
LLoyd Fredenhall. Probably as despised by his subordinates as by thye enemy. Was having combat engineers blast out an HQ some 65 miles behind the lines when Kasserine broke. Had NO concept of armored warfare. Wasn’t sacked. Just reassigned to a stateside command.
Kasserine was one of the reasons Ike didn’t make my list. A critical sector in his command [Ike was ALWAYS concerned with being the on the ground commander], he never visited the area before the attack, and never appreciated the danger it [and Fredenhall] posed. He did the same thing with the Ardennes in ‘44.
