The Qarachil expedition, led by Muhammad bin Tughluq in 1338 CE, was a significant military campaign undertaken by the Delhi Sultanate. While some historians, such as Sir Wolseley Haig, suggest that this expedition was part of a larger Nagarkot campaign, Ziya-ud-din Barani mentioned it as a part of the planned Khurasan expedition. The objective of this expedition was not to facilitate the acquisition of Khurasan or China, as erroneously attributed by later writers such as Firishta and Yahya bin Ahmad. Instead, it aimed to secure India's northern frontier after rounding off all other frontiers. The Sultanate army captured a place called Jidya.[3] In the aftermath of the expedition, even though the Tughlaq army of 10,000 lost their lives due to the advance they made to the mountains, the ruler of that area, made a treaty with Muhammad Bin Tughlaq. Accordingly, the ruler of that area agreed to pay certain money to the Sultan for using the territory lying at the foothills and accepted the overlordship of the Sultan.[1]
. The commander of the Delhi armies advanced too far into the mountains so that his retreat was cut off by the defending forces, and almost the entire army of 10,000 was destroyed. However, this expedition was not a total failure because, after some time, the ruler of the area patched up a treaty with Muhammad bin Tughlaq, agreeing to pay him a certain sum of money for the use of the territory lying at the foot hills. He also accepted the sultan's overlordship.
