|
| 301 | "The General Flipped at Dawn" | September 10 | An inspection by the strict Major General Bartford Hamilton Steele7 puts the 4077th on edge. The final straw comes when he orders the unit to move the camp closer to the front, to be more economic and to show that a MASH unit should be mobile. On an inspection tour of the new site, Steele takes along Blake and Burns. After Steele forces Blake to salute him and all three are shot at by snipers, Steele gives Blake & Burns a choice — fight or have lunch!! (Blake and Burns choose lunch) When Hawkeye sends a chopper off with a patient instead of letting the general use it to scout the new site, Steele calls for a court martial for Pierce and Blake. When Steele goes into a song and dance routine (because the helicopter pilot is Africian-American) the Army hurriedly closes the court-martial and Steele gets sent back to the United States — where he is placed in charge of Northeast Asia!
