Battle with Ali Sher Khan Anchan
Jamyang Namgyal during his reign decided to support the Sultan of Chigtan and to capture Skardu. Namgyal's army was crossing the mountain passes towards Purig during the winter season where his troops disappeared due to violent storm. Ali Sher Khan Anchan's well trained army attacked Namgyal's army on the way and held them there until all the passes and valleys were blocked with snow; compelling Namgyal to surrender. Namgyal was imprisoned by Anchan in Skardu. Ali Sher Khan Anchan then attacked Ladakh, took control of the place, destroyed historical monuments and records. After returning to Skardu, Ali Sher Khan asked Jamyang Namgyal to marry his daughter Gyal Khatun in exchange of his release. Namgyal married Ali's daughter and returned to Ladakh.
