One of the most important sitcoms in television history is M*A*S*H, which stars Alan Alda, McLean Stevenson, Harry Morgan, Mike Farrell, Loretta Swit, and many others. During its run on CBS, the show highlighted many struggles soldiers faced during the Korean War. At times, the show’s most memorable moments reflected the human toll suffered within the confines of a war zone.

A number of memorable moments remain close to fans’ hearts after all these years. Everyone has their own favorites but let’s take a look at five that probably are among them.

The Death of Henry Blake

In the show’s early seasons, Stevenson was a standout cast member. Playing Henry Blake provided him with the chance to be funny when needed but also a steadying hand for the 4077th. Stevenson’s popularity grew. He came to tire of playing the character and wanted something more. That was part of the reasoning to kill off Henry on M*A*S*H. His sendoff included a tender moment between him and Radar, played by Gary Burghoff. Ironically, it would be Radar who would go into the operating room and sadly tell those working on patients about Blake’s plane crashing.

Margaret Becomes Pregnant

Nurses were critical to the daily life and grind. Margaret “Hot Lips” Houlihan secured her lead spot on M*A*S*H as the chief nurse there. In the show’s early seasons, people saw Margaret, played by Swit, be involved with Major Frank Burns, played by Larry Linville. But she would end up getting married to someone else and while with her husband, she became pregnant. It’s memorable for showing Margaret in a new light.

Radar Goes Home

There’s little doubt that Radar was one of the show’s most important characters throughout its run. His childlike innocence in the middle of hell on M*A*S*H provided viewers with a chance to see the Korean War in a different light. By the show’s eighth season, Burghoff had tired of the show’s grind and wanted to leave.

Sherman Potter Arrives on ‘M*A*S*H’

With Stevenson’s character leaving M*A*S*H, a new commanding officer was needed. Enter Colonel Sherman Potter, played by Morgan. Eagle-eyed Potter enters the 4077th only to look over and see Radar trying to get some sun. A light-hearted moment among many heavy ones. Potter’s first appearance comes at the very end of Capt. B.J. Hunnicutt, played by Farrell, making his first appearance.

Hawkeye Loses His Eyesight

In the show’s later seasons, M*A*S*H tended to have a more serious tone to its episodes. Hawkeye would find himself, at times, in the center of a crisis. Such is the case when he loses his eyesight. We see him in a vulnerable state, something that rarely happens to the character. His eyes are bandaged over and he has to rely on others for help when getting around.
