Chamb sector, which is still under our control.
Certainly seems like a bigger achievement considering we still retain control over it, and I'm sure there are other examples.

Yes you did, and it took you 2 whole months to take back 75% of it, despite outnumbering our forces 6 times over, and getting air support as well as resupplies (both of which our forces did not have.
We only evicted most of the remaining 25% of Kargil because of political pressure being applied on Musharaf by the US and the rest of Pakistan. Even then, we still retained several key areas of Kargil such Point 5353 which is the dominating feature, giving us authority over the area.
Clearly you have lost parts of Kashmir post 1947.
You lost over 12,000 people during the heyday of the Khalistan movement, 40,000 people since 1979 due to the insurgency in northeast Hindustan, and 40,000 people in Kashmir since the 90's.
