This is the valley where the former Pakistan president Pervez Musharraf had arrived as the then Pak army chief to give instructions to the Pak intruders regarding the war.
How Pak took advantage of Shimla agreement
In 1972, India and Pakistan had signed Shimla agreement. During the agreement, both countries had agreed to withdraw troops from both sides during winter due to heavy snowfall.
Till 1999, India did not deploy any troops at their posts in winters, but Pakistan took advantage of this situation and started war.
Pak intruders chose Mushkoh Valley as their hideout
India was not even aware that when Pakistani intruders had gained entry in the Mushkoh Valley of Dras, during heavy snowfall.
Experts believe that the reason behind Musharraf's visit to Mushkoh valley was that Pakistan wanted to first take control of the valley and then to seize Kashmir gradually.
