What was Operation Bison? The pivotal capture during the Indo-Pak War

Operation Bison, the codename for a strategic military assault and capture, holds a significant place in the annals of India's military history. This operation, undertaken by the Indian Army during the Indo-Pakistani War of 1947-1948, aimed to regain control of the strategically important areas of Zoji La, Dras, and Kargil districts in the Ladakh region.  

The 1948 Indo-Pak war, also known as the First Kashmir War, stands as a pivotal chapter in the history of the Indian subcontinent. This conflict erupted in the wake of the partition of India in 1947 when the newly formed nations of India and Pakistan found themselves embroiled in a territorial dispute over the princely state of Jammu and Kashmir. The war marked the first military confrontation between these two nations and set the stage for a complex and enduring conflict over the region that continues to influence geopolitics in South Asia to this day.  

Seizure of Zoji La by Pakistani Raiders  

The campaign to capture Ladakh by Pakistani raiders in 1948 saw the seizure of Zoji La, a crucial mountain pass, which posed a threat to India's territorial integrity. Zoji La's occupation by the enemy forces necessitated a decisive response from the Indian Army.

On 1st November, Indian forces launched a daring assault to recapture Zoji La, which marked a significant turning point in the operation. What made this assault even more remarkable was the surprise use of armour, making it the highest altitude at which armoured units had ever operated in combat worldwide.  

From Operation Duck to Operation Bison  

The initial attack to capture Zoji La was conducted by the 77th Parachute Brigade, led by Brigadier Atal. Originally named Operation Duck, this assault was later renamed Operation Bison by Lt. Gen. Cariappa, the Western Army commander.  

To achieve this ambitious goal, M5 Stuart light tanks of the 7th Cavalry regiment were painstakingly transported in dismantled condition through Srinagar and then winched across bridges. Additionally, two field companies of the Madras Sappers converted the existing mule track from Baltal up to Zoji La into a navigable jeep track.  

Surprise attack and success  

On 1st November, the 77th Parachute Brigade, supported by armour and two regiments of 25-pounder artillery, along with a regiment of 3.7-inch guns, executed a surprise attack. This element of surprise caught the Pakistani forces off guard. The pass was successfully forced, and the raider column was pushed back to Matayan and later to Dras. The brigade linked up with Indian troops advancing from Leh on 24th November.  

Meanwhile, the Pakistani forces eventually withdrew northward towards Skardu. Operation Bison's success not only recaptured crucial territory but also showcased the Indian Army's ingenuity and bravery, highlighting their ability to operate effectively at high altitudes. This operation's legacy continues to inspire future generations of Indian military personnel.
