So it appears that they have plans to take and hold territory that more than just small pockets around the LAC border. My question is how many of these locations can be held year around (by India or China) for example, DBO, or areas of Despang plains. Do these areas get snowed in during winter and therefore abandoned?Chinese don't want India anywhere near the Karakoram pass and hence all their effort to push India out of DBO/Depsang plains. Galwan gambit was to choke our line of supplies to DBO/Depsang and get India to concede.
Apart from DBO road getting completed, there is another factor that make the timing critical. There is an alternate supply route under work i.e. the "Sasoma-Saser pass-Murgo" route, which will act as a backup for logistics to DBO/Depsang. AFTER that bypass is completed, Galwan gambit's relevance would have reduced considerably.
The DBO/Depsnag gambit via the Galwan gambit had to be executed before completion of the alternate route at the latest but preferably as early as possible before India further hardens its defenses in DBO/Depsang via the primary route along the Shyok river.
I dont know for a fact but I am pretty sure if there is any loss of territory, GOI will use air assests to hit supply lines and logistics in the Tibet plateau/hinterland and not jsut the border, in Octoer, December and even January 2021. I dont know how China plans to support a division strength presence in that area through the winter (unless they are parked in PoK, which gives credence to (rumours) of why they would be landing their fighers in Skardu). If they planned for this, there must be some signs of it in terms of large supply dumps, roads with heavy military traffic etc. because this could go on for months.
