The most romantic way to die is leading a group of people through war torn territory and then getting them safely to the coast. You put them on a boat and you go back to blow up the bridge so the soldiers will be stopped long enough for the boat to get beyond the range of their bullets.
The explosives don't work properly, so you have to drag a big machine gun up a hill and fire for a minute or two to scatter the enemy. Then you run over to the bridge and manually set off the charges which messes you up severely. You are knocked unconscious for possible a few minutes and then you come to.
You see the people you struggle to save off in the distance where they are safely on their way to a waiting ship.
Your mission is accomplished. You have blood running all over you and your spine hurts and your legs are numb. You lose consciousness and pass away.
