Gen. Benedict Arnold, 1780: This infamous Revolutionary War general became synonymous with treason when he tried to hand over his command post, the American fort at West Point, N.Y., to the British. After the plot was exposed, Arnold joined the British Army as a brigadier general. Arnold is seen here in a copy of an engraving by John Trumbull made in 1879. Newscom/FILE
Gen. George McClellan, 1862: President Abraham Lincoln fired this Union general after McClellan refused to move his troops as aggressively as the commander in chief wanted. ‘You may find those who will go faster than I, Mr. President,’ McClellan said, ‘but it is very doubtful if you will find many who will go further.’ McClellan unsuccessfully challenged Lincoln in the 1864 presidential election.

Brevet Maj. Gen. George Armstrong Custer, 1876: Custer became the youngest American general when he was appointed to the temporary rank of brigadier general on the Civil War battlefield at 23, but he is remembered for his actions known as ‘Custer’s Last Stand,’ at the battle of Little Bighorn in the Montana Territory, June 25, 1876. A force of Lakota Sioux and Cheyenne Indians overwhelmed Lt. Col. Custer and about 210 troops after Custer disastrously split up his Seventh Calvary units before the battle.

Gen. Douglas MacArthur, 1951: An American hero after serving as the senior military commander in the World War II Pacific theater, MacArthur got himself fired in the middle of the Korean War for openly flouting President Harry Truman’s directives. Relations with the Truman administration were already deteriorating when the United Nations put MacArthur in charge of UN forces in the Korean War, but the final straw was MacArthur’s release of an unauthorized, veiled threat to expand the war into China. Truman subsequently relieved the general of his duties. MacArthur is seen here with Emperor Hirohito during the Japanese emperor's visit to the US Embassy in Tokyo in 1945. AP/FILE
Gen. Curtis LeMay, 1965: The Air Force Chief of Staff seen here was forced out of office, after 35 years in the Air Force, after constant bickering with President Lyndon Johnson and Secretary of Defense Robert McNamara about the administration’s political and strategic approach to the Vietnam War. LeMay – who planned strategic defense for World War II and the cold war – favored (loudly) a more intense bombing campaign than Johnson. Newscom/FILE
Gen. William Westmoreland, 1968: The commander of American military operations in the Vietnam War since 1964, Westmoreland fell out of favor with President Lyndon Johnson after the Tet Offensive began in January 1968. Westmoreland defied the counsel of advisers to recommend the president mobilize military reserves and send an additional 206,756 troops during a time of mounting casualties and public opposition to the war. On March 22, Johnson announced he was ‘promoting’ Westmoreland to Army Chief of Staff and replacing him in Vietnam with Gen. Creighton Abrams. Westmoreland is seen here in January 1972. AP/FILE
Surgeon General Jocelyn Elders, 1994: President Bill Clinton made Elders the first African-American surgeon general in 1993, but Vice Admiral Elders served for only 15 months before she resigned over controversial comments suggesting that masturbation be included in sex education programs. She was similarly outspoken on other public health concerns including substance abuse and birth control. Elders speaks at E. J. Thomas Performing Arts Hall at the University of Akron in September 1999. Newscom/FILE
Gen. Peter Pace, 2007: The chairman of the Joint Chiefs of Staff came under fire in 2007 for calling homosexuality ‘immoral’ in his defense of the military’s ‘don’t ask, don’t tell’ policy. Pace apologized for airing his personal views, but the 40-year soldier was replaced as chairman when his term ended that same year.

Adm. William Fallon, 2008: Fallon’s 42-year career in the Navy ended in March 2008 when a magazine story led to his resignation as chief of US Central Command. An Esquire article, 'The Man Between War and Peace,' portrayed the admiral as a bulwark against the Bush administration’s desire to attack Iran. This followed similar public statements by Fallon, including an interview with the network Al Jazeera, in which he said, "This constant drumbeat of conflict ... is not helpful and not useful.”

Gen. David McKiernan, 2009: McKiernan was the top general in Afghanistan for less than one year before Defense Secretary Robert Gates demanded his resignation last May. He was replaced by Gen. Stanley McChrystal. Though no specific incident precipitated his removal, McKiernan was considered to have failed to adapt and contain the morphing Taliban insurgency in Afghanistan.McKiernan is seen at Forward Operating Base Airborne in Wardak Province, Afghanistan, on May 8, 2009, during a visit with Secretary Gates.

Gen. Stanley McChrystal, 2010: President Barack Obama relieved the top US military commander in Afghanistan of his duties on June 23, after publication of a Rolling Stone article in which he made disparaging remarks about members of Obama’s national security team. Gen. David Petraeus, commander of US Central Command, succeeds him. McChrystal had previously replaced Gen. David McKiernan, who was ousted in May 2009 after less than one year in the post.
