That man was Brigadier General Hoshiar Singh,in charge of the defenses of the Sela.And let me tell you something,he never ran away.The exact word you are looking for is withdraw.Yes,they were in the process of withdrawing as per the directives of then Major General Pathania,GOC of 4 th Infantry division.Now why did he issue such an order is beyond my understanding because the defenders had enough supplies to last them a week and could be air supplied.But regardless,they were ordered to abandon their positions and he had to obey it.But that doesn't mean he ran away or something!!
Actually,the problems were many fold for the Indian side,the men in the higher commands were largely incompetent.Because many of them were chosen on the basis of their loyalty to Political heads instead of their merits or commanding abilities.So as soon as the PLA had stuck,the first thing that happened was near total collapse of command failure,many conflicting and confusing directives were issued to the sector commanders.It was total chaos everywhere.No matter what you or Chinese Dragon have to say,but the reality is,in 1962 the Indian Army was not in a position to even defend itself against the then very battle hardened and experienced PLA ,who had gained valuable experience in mountain and guerrilla warfare during the years of the Korean war.So the question of India attacking first never arises.
