I don't remember any of the actors, but it's a war flick made in the 90's. It's about WWI when the allies were stuck in the middle of a forest surrrounded by the Germans who for days had been trying to kill them. Eventually a fighter jet was bale to fly over and get their location for the allies but on his way back he was shot and killed, but the allies still got the info so they could bomb the Germans and get their men out of the forest. What's this movie called?

Was this a WWI era war movie? Were there jets of prop planes? Jets were not (technically) in any conflict until the Korean war. After WWII. Maybe this will help you clarify your own memory so that you can find the title. Good luck.

Perhaps "Cross of Iron" with James Coburn ?

I think its called "The Lost Battalion" starred Rick Schroeder
