Editing Battle of Dien Bien Phu (section)

===Disaster in the Central Highlands===
Following the fall of Dien Bien Phu the French high command gave the order for any isolated positions to be abandoned, to avoid another disaster. The area of concern was the isolated defensive positions in the [[Central Highlands (Vietnam)|Central Highlands]] at [[An Khe]]. ''Groupement Mobile No. 100'' ("Group Mobile 100" or G.M. 100) which included the elite veteran [[United Nations|UN]] ''[[French Battalion in the Korean War|Bataillon de Corée]]'' was ordered to abandon the area and fall back to [[Pleiku]], some 50 miles away over [[National Route 19 (Vietnam)|Route Coloniale 19]]. Code named ''opération Églantine'', GM.100, however were hit in a series of deadly ambushes at the [[Battle of Mang Yang Pass]], suffering heavy losses in men and vehicles by 29 June and the remnants struggled back to Pleiku.<ref name = 'another DBP'>{{cite web|url=http://www.baobinhdinh.com.vn/562/2004/5/10363/|language =vi|title = Có một Điện Biên Phủ ở Liên Khu 5 |trans-title=There was another Dien Bien Phu in 5th Military Region|publisher=|access-date=6 November 2014|website = baobinhdinh.com.vn (Bình Định Newspaper)|date = 3 May 2004 }}</ref>

The French then needed to keep ''Route Coloniale 14'' between Pleiku and [[Ban Mê Thuột]] open and withdraw the units posted there. Operation ''Myosotis'' ''(Forget-Me-Not)'' began - 'Groupement Mobile No. 42' (GM.42) in an armoured convoy was sent to relieve the units, but were ambushed at the [[Battle of Chu Dreh Pass]] on July 17, just four days before the armistice suffering further heavy losses and the almost complete destruction of Bataillon de Corée.{{sfn|Fall|2005|p=240}}
