Help me identify this MASH episode.

I saw this episode once and it was very good. I’m trying to figure out the name of episode so I can tell others to watch it.

Hawkeye is driving a jeep, it runs out of gas and stalls. A North Korean soldier finds him and realizes that Hawkeye is a doctor. He leads him a gunpoint another North Korean who is wounded. The two are unable to communicate as the speak different languages but Hawkeye realizes he must save the save wounded man or he will be shot.

I don’t want to spoil the ending for anyone who hasn’t seen it but if anyone had seen it, it would great if you told me the name of the episode.
