The only reason we retain NEFA is thanks to the fact that mountain passes close in winter, and PLA could not ensure logistics to its troops in NEFA..
The eastern front in NEFA was a complete humiliating rout for the Indian Army, except for the Battle of Walong where 6 Kumaon displayed remarkable courage, and held on until they were finally surrounded..
The PLA had reached the Assam border at Bhalukpong. They had completely driven Indian army out of Tawang sector.. After kicking Indian Army out of Arunachal /NEFA, they declared a unilateral ceasefire and retreated from Entire NEFA, as winter was upon them..
We should not have any illusions of 1 Indian Army soldier = 10 PLA Ch*nks.. As similar illusions of 1 Marde Momin = 10 Hindu Pajeets has done in the Pakistan Army more than once..
Note: Walong was the only Indian counter attack in the entire War, and was a failed one.. The entire War, Indian Army was on the defensive, and busy retreating..
