MASH actor Loretta Swit reveals that she disagrees with Margaret Houlihan's finale fate. In 1983, CBS' groundbreaking medical war comedy/drama wrapped up its 11 seasons with a feature-length send-off to 4077. With the Korean War ending, the doctors, nurses, and other personnel from the unit were excited to get back to their old lives back in the United States. Wrapping up their stint in Korea forced her to contemplate what was next for her. In the end, Margaret decided to also come back to America to work at a local hospital.
