Exploring the battle sites around Nghĩa Lộ
April 2025. Ba Khe, near the village of Cát Thịnh, Yên Bái Province, Vietnam. I am exploring the old Route Coloniale 13 west of Yen Bai, retracing the ground fought over during the October 1951 battle for Nghĩa Lộ. This is steep, broken country. The road winds through flat valley floors, overlooked by sharply rising hills on all sides. Movement is constrained to these mobility corridors.
We worked our way through the old French positions at Ca Vinh, Son Buc, Ban Tu, Nghĩa Lộ, and Gia Hoi. Each position occupies ground that makes immediate sense when you stand there—small posts positioned to control tracks, valleys, and key approaches. But it was Ba Khe, just south of Nghĩa Lộ, that really stood out for me.

An untouched time capsule
Ba Khe is one of those rare battlefield sites that has been left almost completely untouched. It is a steep climb through dense vegetation to a small hilltop position that few people visit. At the top, the remnants of a French company position are still there. The trenches are visible. Machine-gun bunkers, mortar pits, and the command post can all still be identified clearly. Nothing has been ploughed over, restored, or heavily disturbed. It remains very close to how it was when the French held it in 1951.
Importance of Ba Khe
As a piece of key terrain, it is exceptional. The hill dominates the surrounding approaches, but it is not large. The position is compact, with fields of fire carefully arranged to cover likely avenues of attack. The slopes are steep enough to slow movement and break up formed assaults. When reinforced with mines and barbed wire and covered by machine gun and artillery fire from flanking positions, it would have been a formidable defensive position. Once you are on the position, it is clear how difficult it would have been to take, even with superior numbers. It is also clear how isolated it was.
The Ba Khe position was constructed by French forces in 1948. It was strategically positioned on a saddle-shaped hill, with the Ky Lan stream flowing behind it, and was sited to cover the Ba Khe valley and Route Coloniale 13 a few hundred metres to the north. The military huts and structures on the position were primarily made of wood, rammed earth, and other natural materials. They are gone now, leaving only the remnants of the dugouts and bunkers.
