The strategy of pushing the Việt Minh into attacking well-defended bases in remote parts of the country at the end of their logistical trails was validated at the Battle of Nà Sản even though the base was relatively weak because of a lack of concrete and steel. French efforts were made more difficult due to the limited usefulness of armoured tanks in a forested and mountainous environment, lack of strong air forces for air cover and carpet bombing, and use of foreign recruits from other French colonies (mainly from Algeria, Morocco and even Vietnam). Võ Nguyên Giáp, however, used efficient and novel tactics of direct fire artillery, convoy ambushes and massed anti-aircraft guns to impede land and air supply deliveries together with a strategy based on recruiting a sizable regular army facilitated by wide popular support, a guerrilla warfare doctrine and instruction developed in China, and the use of simple and reliable war material provided by the Soviet Union.
