I. Overview of the Route Coloniale 4 

Route Coloniale 4
The Route Coloniale 4, or RC4, is a famous name among Indochina War veterans and history enthusiasts. This road was vital for communication in Indochina, especially during the Indochina War. Located in northern Indochina (Tonkin), it ran 200 km along the Chinese border. Many battles occurred here between French soldiers and their enemies, including the Black Flags, the Japanese, and the Viet Minh, highlighting its strategic importance during the war.
 

II. Explore the myth of the Route Coloniale 4

The mythical Route Coloniale 4
The Route Coloniale 4, also known as Highway 4, is a mountain road in Vietnam that runs along the Chinese border between Hanoi and Cao Bang. It is notorious for the French military disaster in 1950, when several French army units, including battalions of the Foreign Legion, were decimated by the Viet Minh and ceased to exist as fighting forces.
 
Surrounded by hills and mountains and sometimes cutting through steep cliffs, this road was ideal for ambushes. This vital supply route for the French base in Cao Bang had already been targeted by repeated ambushes between 1947 and 1949. RC4 saw fierce clashes involving French soldiers against the Black Flags, the Japanese in 1940 and 1945, and especially the Viet Minh from 1947 onward. The Battle of RC4, called the Autumn-Winter Border Campaign by the Viet Minh, was a key fight in the first Indochina War. During these battles against the Viet Minh, the French suffered one of their heaviest defeats, earning RC4 the grim nickname "the bloody road."
