In 1984, the Indian Army carried out a stunning operation that captured the Siachen Glacier in the northernmost regions of what is now the Union Territory of Ladakh. Since that time, a full brigade of Indian troops has faced off against a similar number of Pakistani soldiers in the highest battlefield on earth. Sustained by a combination of tenuous road supply lines and air support, where helicopter manuals have had to be rewritten, the two countries have had numerous skirmishes that have escalated into the use of artillery fire. Operation Meghdoot tells the story of this conflict. Beginning with the trauma of partition and the first Kashmir war that saw the region divided between India and Pakistan, it progresses to the 1962 Sino-Indian war which saw the Aksai Chin region lost to China and the Shaksgam Valley unilaterally ceded by Pakistan to China. The consequence of this was to allow the development of the Karakoram Pass and highway to link China to Pakistan.
