Summary
Operation Meghdoot was the codename for an Indian Armed Forces operation launched in 1984 to preempt Pakistan's competing Operation Ababeel to take full control of the Siachen Glacier in Ladakh on the tri-junction of the India–Pakistan-China border in the Himalayas.
Objective
Pre-empt Pakistani occupation of the Siachen Glacier by taking the Saltoro Ridge passes first.
Outcome
India holds the ridge and the glacier. The operation has never formally ended — it is the highest-altitude military deployment in the world, and has continued for over forty years.
A war decided by a map
The 1949 ceasefire line was drawn only as far as a point on the map called NJ9842, and then described as running 'thence north to the glaciers' — a phrase precise enough for 1949 and useless afterwards. Both states read the ambiguity their own way, and mountaineering permits issued by Pakistan in the early 1980s were what turned the reading into a race.
The cold does the killing
For most of the operation's history the weather has caused more casualties than the fighting: altitude sickness, frostbite, avalanche and crevasse. Everything a post consumes has to be flown or carried up, which is why the Cheetah — a helicopter designed in the 1960s — remains irreplaceable at altitudes where nothing else can hover with a load.
Losses — contested
Well over a thousand Indian soldiers have died on the glacier since 1984, the majority from the conditions rather than from combat.
