In the war movie, The Bridge on the River Kwai (1957), at the end Major Warden has a brief dialog with the women porters.
The women back away from him as he exclaims:
I had to do it. They might have been captured alive. It was the only thing to do!
I don't understand this part of the film. At least it did not appear that he was trying to fire the weapon at the commandos (Shears and Joyce). In fact the only time an explosion occurs near them is after they are dead and a explosion lands near Colonel Nicholson.
