Battle of Nà Sản
Nà Sản, Sơn La Province, Vietnam
In the Battle of Nà Sản, starting on October 2, French commanders began using "hedgehog" tactics, consisting in setting up well-defended outposts to get the Việt Minh out of the jungle and force them to fight conventional battles instead of using guerrilla tactics.
