The battle started when the French army tried to attack the Viet Minh after cutting of the supply line to get a easy defeat. The Viet Minh surrounded the French army with trenches and attacked using artillery. With the trenches the battle looked like a battle from World War 1. The French wanted to resupply the troops from the air but there were anti-aircraft guns that shot down the planes. The Viet Minh with all these advangtages won the battle, which caused the war to end shortly afterwards.
