Military operations took place in Ladakh in 1948 during the conflict in Jammu and Kashmir between the Indian Army and Pakistani raiders infiltrated to capture the kingdom of Jammu and Kashmir by JAT REGIMENT. The eviction of this invading force of tribal raiders, who enjoyed numerical superiority, better lines of communication, commanding high ground and superior logistics, was a major military achievement for the small force of Indian soldiers.
Pakistani raiders had besieged and reduced Skardu in early 1948. It was vital that Leh, the next likely target, be relieved before it was attacked by the raiders. Maj Prithi Chand, a Lahauli officer with a band of 40 volunteers from the 2nd Battalion, JAT Regiment began a hazardous mid-winter ascent of Zojila pass on 16 February 1948, with rifles and ammunition for the garrison. They reached Leh on 8 March, where an ad hoc force for defence was organised, followed soon by a Jammu and Kashmir State Forces detachment bringing additional weapons.
The slow advance of raiders permitted reinforcement of Leh by air by a coy of 2nd Battalion, 4 Gorkha Rifles (2/4 GR) and later a coy of 2nd Battalion, 8th Gorkha Rifles (2/8 GR) by air just in time to repulse the raiders. Had the raiders kept advancing they could have captured Leh easily. The garrison of Leh held despite shortage of troops, weapons and ammunition, sickness and fatigue. In August another coy of 2/8 GR was flown in by air and the remaining part of the battalion, codenamed Arjun column, with a large column of supplies on mules, trekked to Leh from Manali. Another large mule column, codenamed Chapati column, followed in September to provide adequate supplies for the winter. Lt Col (later Col) HS Parab, CO 2/8 GR, was airlifted to Leh on 23 Aug and later designated Commander, Leh Brigade (though the force never exceeded two battalions in strength). Spirited small unit actions and guerilla raids on both banks of the Indus effectively held the raiders at bay throughout September and October.
