What are the step the French could have taken to ensure their defense of Dien Bien Phu was much stronger and managed even to inflict casualties on the Viet Minh.
I supposed one of the biggest changes would be to have a bigger presence on the overlooking and surrounding hills to prevent the Viet Minh artillery from dragging their artillery over the hills. I doubt they'll be able to protect all of the hills but enough to keep up their defensives longer.
Having artillery with longer range that is capable of counter-battery fire to reduce the effects of the artillery fire from the Viet Minh.
Having a closer supply base so their air support wouldn't have to travel as far and back.
