The Galwan Valley clash is a significant military act that occurred on the night of June 15, 2020, between the Indian Army and the Chinese People's Liberation Army (PLA) in the Galwan Valley of Eastern Ladakh. It was the deadliest confrontation between the two nations in over four decades, resulting in the death of 20 Indian soldiers, including the Commanding Officer of the 16th Bihar Regiment, Colonel B. Santosh Babu. The clash originated from a weeks-long standoff that began in May 2020, triggered by China's objection to India's infrastructure projects, such as the construction of a strategic road in the Galwan River Valley that connects to an important airbase.
The mechanism of the clash involved a brutal, hand-to-hand physical confrontation near Patrol Point 14 (PP-14), which was a direct violation of a prior disengagement agreement reached on June 6, 2020. The immediate cause was the Indian patrol, led by Colonel Babu, confronting Chinese troops who had reneged on the agreement and re-established a post in the area. Crucially, no shots were fired, as the clash was governed by the 1996 Agreement on Confidence-Building Measures which prohibits the use of firearms or explosives within two kilometers of the Line of Actual Control (LAC). Instead, the soldiers fought with stones, iron rods, and clubs, with some casualties resulting from falls into the freezing Galwan River.
The clash connects directly to the long-standing, undemarcated border dispute along the LAC and the 1993 Border Peace and Tranquility Agreement (BPTA), which mandates that neither side shall use or threaten to use force. The incident marked a watershed moment, ending a 45-year period without loss of life on the LAC. Since the clash, a series of military and diplomatic talks have led to disengagement from friction points like Galwan and the northern bank of Pangong Tso. More recently, a new patrolling arrangement was agreed upon in October 2024 to restore patrolling rights in areas like Depsang and Demchok to pre-2020 levels, aiming to ease hostilities and reduce confrontation.
