不要说战后越军在北部战场集中主力,就连战中就已经调第2军从柬埔寨回援,这是一位越南网友“gold star“当年和我讨论时说的话:
Because our regular troops had to fight in Cambodia. However, we had used 3rd and 316th divisions, in most important fronts (Lang Son and Lao Cai). After PLAs captured Lang Son, VPA's command planned to counter-attack and retake Lang Son on Mar 6th or Mar 7th. They had moved 304th and 325th of 2nd corps from Cambodia to Lang Son, some armor and MRL regiments were also appointed. But before we finished all preparations, PLAs had retreated.
Our leaders didn't want to let the war develope. Three days after PLA attacked, VPAF deployed hundreds of fighter-ground-attacks. But our leaders didn't accept them to join battles.
