An announcement is made at the flower show that hundreds of enemy planes have been seen in the area. Everybody must hurry to their bomb shelters. Mrs. Miniver and Carol casually load up Vin in their personal car and drive him to the airfield. England is supposed to be all chivalrous about their women yet the military depends on two women to transport a soldier to his post during wartime. It also led directly to the death of one of them.
shareYou're missing the whole point of the film - it wasn't just the soldiers' war, it was everyone's war. Remember the Minivers' maid who left to join the WAAF? Or their cook who left to cook for the army? Even Mrs. Miniver herself was left to capture the German airman while her husband was away assisting the evacuation of the British Expeditionary Force from Dunkirk.
Having the young wife be killed by German planes after delivering her RAF husband to the battle was the ultimate expression of that theme. And, for good measure, they killed off an innocent choirboy and the lovable, elderly station master. It was all designed to build empathy in civilian America. The director admitted that this movie, the screenplay for which was written before Pearl Harbor was attacked, was a propaganda effort to inspire America to join the war.
