E1 Hill (Dominique 1) belonged to the Dominique Group protecting the French Hedgehog at Dien Bien Phu from the northeast.

E1 is 1.9km from the French Commander Post (approximately 1.2km via a beeline). Originally the hill was about 60-70m high from the ground. From E1, all movements on Route 41, the French Central Zone, and the Muong Thanh Airport were visible.
