QuangBinh is the final resting place of one of the Worlds famous military generals of all time.
Defiantly on my next list of places to visit being the hometown of General Vo Nguyen Giap who died in 2013 at the age of 102 and now buried not far from Kien Giang ( on the coast ).
I've cycled 5 times from Da Nang to Dien Bien Phu where General Giap along with the leadership of Ho Chi Minh defeated the French at what would go down in history as the final battle that ended French rule over Indo Chine for 100 years. General Giap's mountain HQs is still in place approx 40kms from the city of Dien Bien Phu as is the French military strategic emplacements in and around Dien Bien Phu city which were eventually overrun by the Viet Minh in 1954, the battle controlled by General Giap himself from his secret mountain based Headquarters.
I've also visited there with a few ex Australian soldiers in the past as part of a battlefield tour group and can highly recommend a visit to Dien Bien Phu including a visit to General Giap's underground HQ ( military command centre ) and Politburo Office in Hanoi where the American war was controlled from deep underground Hanoi suburbia.
