70's or 80's world war 2 movie

Was at my friends house a couple of years ago and i watched a movie about troops and people caught up in a farmhouse . They have to build makeshift bombs from ammo and use sabotage to fight off a german tank advance . It may have been a made for tv movie ...i think it was on tcm , but it was really good.

Its not a bridge too far or Blockhouse .

I cant remember the name, any actors or directors . All i know is it was a good almost sleeper type movie . We were hanging out just to talk fishing and by the end we were just riveted.

Any help would be appreciated. Thanx !
