With merely an element of surprise, and an advantage of height. The only reason you were able to perform initially. Those are one of the toughest peaks to even climb from the Indian side, let aside having a battle. Any one perched at the top can command the whole theater.
Pakistan Army chickened out of the fight when the real battle came, instead chose withdrawal. Would have considered PA a worthy adversary had they slogged on and held the peaks, come what may like Indians did at Siachen.
And since the war didn't change the status quo, now deserves the question whether any of the objectives of PA for these operations were met? At any level? Except giving Musharraf a chance for a coup.
Few tops were taken, others are still held by Pakistan after taking them during Kargil. Point 5353 was attacked by india on multiple occasions but indians were beaten back every time, and Pakistan Army still holds the highest peak (P. 5353) in drass sector.
Secondly indians had to bring entire
brigades to handle few hundred Pakistani troops on top. Even that failed, and then indians brought their air force and Israeli experts helped you in guided targetting. Even all of this, and you still couldn't take back all of the peaks taken by Pakistan Army. Only a few.
In terms of chickening out, indian army itself recommended Pakistani officers for highest medal for bravery precisely because of their sheer will to not give up. After indians, who deployed remarkably larger forces numerically, took back the Tiger hill---Pakistani troops, small in number and in extreme disadvantaged position, chose to launch an impossible counter strike on numerically superior indian forces which were sitting on higher ground. That counter strike was so ferocious than indian Army
itself recommended Kernal Sher Khan (Rank: Captain) for a prestigious military award for his bravery and sheer will.
It's the type of military acumen unknown to Hindus historically----who are known to give up rather quickly.
You want to see real "chickening out"? See what happened in 62 when indian army humiliatingly left the field on first contact with the Chinese. Pakistani forces will never do that...
ever (and please, don't bring a
civil war of 71 to salvage your childish ego in the face of facts. No army is gaged on the basis of
civil conflict when their own take up arms against them, ranks fall, and political bloodbath takes over. Even the mighty Soviet Army crumbled and lost gigantic chunks of land once the civil unrest ensued. The same Soviet Army that had defeated the Nazi war machine, mind you).
Pakistan had to withdraw from Kargil because of the political debacle on diplomatic level. Everyone knows that, even indian generals who have given interviews on the issue
Pakistan had infiltrated Kargil at multiple sectors--majority of them were not even 'touched' yet. But the entire effort became "too hot" for Pakistan to handle in the face of mounting international pressure and inter-institutional disputes within Pakistan. indian military effort was rather unimpressive and did not cause Pakistan to even think about withdrawing.
