Yes, it is true that the British sought to gain control over Myanmar (then known as Burma). This objective was realized through a series of Anglo-Burmese Wars in the 19th century, resulting in the gradual annexation of Burma into British India.

• First Anglo-Burmese War (1824-1826): This war began due to conflicts over territory and trade along the border between British India and Burma. The British emerged victorious, gaining control of Arakan and Tenasserim.
• Second Anglo-Burmese War (1852): This war resulted in the British annexation of Lower Burma, driven by economic interests and the desire to control the Irrawaddy River delta.
• Third Anglo-Burmese War (1885): This war led to the complete annexation of Upper Burma, effectively bringing the entire country under British rule. The British exiled the Burmese King Thibaw Min and established Burma as a province of British India.

The British aimed to exploit Burma's natural resources, including teak, oil, and rice, and to secure a strategic foothold in Southeast Asia.
