In April 2006, six prominent retired generals publicly criticized Secretary of Defense Donald Rumsfeld's handling of the war, and called for his resignation. The group included two generals who commanded troops in Iraq: Maj. Gen. Charles H. Swannack, Jr. (Ret.) and Maj. Gen. John Batiste (Ret.). One of the generals, Lieut. Gen. Greg Newbold (Ret.), who served as the Pentagon's top operations officer during the months leading up to the invasion, also published an article that month in Time Magazine entitled "Why Iraq Was a Mistake."
