70's or earlier War Movie, was in color. Movie took place during WWI (maybe later or earlier). It's about a boy who becomes an orphan after his village is raided. He has a childhood female friend and later gets reunited when they are adults. He joins the military and becomes a prominent soldier as he works his way up the rankings. Final scene, he's walking through an abandoned town (I think Europe) and gets shot by an enemy hiding in a tower or 2nd floor.
