What was the title of the episode in which Colonel Henry Blake dies?

The episode in which Colonel Henry Blake dies is titled “Abyssinia, Henry.” It is the 24th and final episode of M*A*S*H’s third season, first broadcast on March 18, 1975.

In the episode, Henry Blake receives an honorable discharge and leaves the 4077th Mobile Army Surgical Hospital to return home. After his departure, Radar O’Reilly enters the operating room and reports that Blake’s plane was shot down over the Sea of Japan, with no survivors. The sudden announcement shocked viewers because Blake had been a central, warmly comic character.

The title contains a period slang joke: “Abyssinia” was used as a playful shortening of “I’ll be seeing you,” while also referring to the former name for Ethiopia. The episode was especially controversial because McLean Stevenson, who played Blake, was leaving the show. Its tragic ending also signaled M*A*S*H’s growing willingness to confront the human cost of war.
