On Jan. 31, 1954, the Dien Bien campaign command headquarters moved from Na Tau village to Muong Phang, a mountainous area in the east of the Muong Thanh strategic zone in the northern Dien Bien Province, due to a switch in strategy.
It was the third and final destination for the headquarters, which stayed there until May 15, 1954, devising important decisions to secure victory over the entire battlefield.
