Red October
In what became known as theHalloween Massacre,Ford nearly did just that. On November 3, 1975, the president announced that Rockefeller had withdrawn from the ticket and that George H.W. Bush had replaced William Colby as director of the CIA. Schlesinger, too, was out, to be replaced by Rumsfeld. Kissinger would remain secretary of state, but Brent Scowcroft would replace him as national security adviser. And Cheney would replace Rumsfeld, becoming, at age 34, the youngest chief of staff in White House history.

'''CHAPTER II
THE HUNT FOR RED OCTOBER: TEAM B
CONFRONTS THE CIA'''
When Colby blocked PFIAB'srequest, it is important to realize that,
technically speaking, he had been fired already. Colby's dismissal was just
one dimension of President Ford's so-called "Halloween Massacre," a cabinet re-shuffling during the first week of November 1975 that would have a
profound impact on American history. According to most historians, Donald
Rumsfeld, Ford's chief of staff, was at the center of the dramatic shake-up.
This skillful bureaucratic maneuver ousted both Colby and Secretary of
Defense James Schlesinger, who had served briefly as CIA director 'in 1973.
Rumsfeld replaced Schlesinger at the Pentagon, while George H. W. Bush
was appointed to Colby's position. Henry Kissinger remained Secretary of
State, but he was forced to relinquish the title of National Security Advisor to
Brent Scow croft. Richard Cheney, one of Rumsfeld' s closest allies, became
Ford's new chief of staff. He was only thirty-four years old at the time, but he
had already established a reputation for getting things done.11
Colby remained in charge at the CIA until the Senate confirmed Bush
late in January 1976.
