Blake’s warm demeanor compared to some ofMASH’s other charactershelped balance the rigors of war all around the dark edges of the show during its first three seasons.

After a tearful goodbye on the helicopter pad, Blake is whisked away from the base for the last time as the surgeons head into the OR to treat a wounded soldier. A short time later, a strickenRadar (Gary Burghoff)returns to deliver the shocking news: “Lieutenant Colonel Henry Blake’s plane was shot down over the Sea of Japan.It spun in. There were no survivors.” The unprecedented moment was a tough pill to swallow for the show’s dedicated fans and a true flashpoint inMASH’s groundbreaking 11 season run.

MASH’s Braintrust Stood By The Decision That Left Even Cast Members Stunned
Sitcoms aren’t usually the land of crazy plot twists and gutting character deaths. Blake was not only a lighthearted, beloved character, butMASHhad quietly established itself as a true comfort show for viewers. For an audience desperate to find any moments of light in war less than a year after the end of the Vietnam conflict,Blake’s off-camera death felt like a rude slap in the face to many of its fans.
Despite the fan backlash,MASHshowrunner and co-creator Larry Gelbart stood by the decision, saying the show’s writers wanted to remind viewers that even thoughMASHwas a comedy, it was still centered on the realities of war – and tragedy could be just moments away. “We wanted to be able to show what that was like by having somebody that America knew and had a fondness for…when you lose a character like that,“MASHproducer Burt Metcalfe told theArchive of American Television.

In fact, Gelbart and company knew very well the possible hornet’s nest of reaction the painful episode might unleash. Radar’s announcement ofBlake’s death wasn’t originally included in scripts given to most of the cast. They expected Radar to report that Blake was safe and sound back in the world. Instead, Burghoff was given his real lines just minutes before the scene was shot, eliciting genuinely shocked reactions from the other characters.

New Characters And Darker Themes May Have Ensured MASH’s Ongoing Popularity
While Blake’s death rattledMASHfans, it was only the first major shift that made “Abyssinia, Henry” such a series-changing episode. It also turned out to be thelast episode for Trapper John McIntyre (Wayne Rogers), one of the original main characters. During the hiatus between seasons 3 and 4, Rogers decided he’d also grown tired of the series and departed. While Trapper’s exit didn’t carry the dramatic weight of Blake’s shocking death (Trapper John left the 4077th off-screen), the dual loss marked season 3 as a major transitional period for the series.
The changes were both cosmetic and tonal.Henry Blake was replaced by Colonel Sherman Potter (Harry Morgan), who brought a calm authority in place of Henry’s bumbling likability.

Honeycutt (Mike Farrell), whose easy chemistry withBenjamin “Hawkeye” Pierce (Alan Alda)expanded what the show could do with its core pairing.
