In 1951, Major Bob Khathing Ralengnao led a peaceful expedition to integrate Tawang into India, hoisting the national flag without any violence amid concerns over Tibet's annexation.
Tawang, located in the eastern Himalayas, had long been a loosely administered frontier region. Even after the 1914 Shimla Convention designated it as part of British-Indian territory, its status remained ambiguous. The situation escalated in 1950 when Mao Zedong annexed Tibet, prompting alarm in India over potential border threats.
To address this, Major Bob Khathing Ralengnao, a Manipuri Naga officer, was tasked with securing the area. On February 14, 1951, he successfully hoisted the Indian Tricolour in Tawang, achieving integration without firing a single shot. This accomplishment marked a significant diplomatic and administrative success, contrasting with the challenges faced by the British in the region.
The event underscored India's proactive approach to its northeastern frontiers during a period of regional instability. Khathing's efforts ensured Tawang's formal inclusion in Arunachal Pradesh, contributing to the stability of India's borders.
