Insubordination in the Past

Been reading a couple of good books: World War II at Sea, and President Carter which remind me of past instances of insubordination in different executive branches.  Some instances, not from the books:

1. FDR was told by a top naval officer before WWII the military did not have faith in his leadership.  
2. Churchill's military continually questioned his judgment, with good cause according to most historians.
3. Joe Califano resisted Carter's efforts to remove education from his HEW to establish a separate Education Department.  Carter ended up firing 3 cabinet officers and almost had his VP resign.
4. Much of Lincoln's military, particularly in the early years and especially Gen. McClellan, openly dissed the president. 
5. Andrew Jackson ended up firing his cabinet to resolve dissension.
6. Ronald Reagan--well, I won't start on him.

So our current president's troubles are not entirely unprecedented.
