Yuma Crossing
Immediately after the Mexican–American War in 1848, the U.S. Army built Fort Yuma here to protect travelers from Indians raiding the area. It was the center point of conflict in the Yuma War of 1850–53. From 1864–1890, the fort and nearby facilities was the main army base to support the US Army's efforts to control the Indians throughout the greater southwest.
British rule in Burma
Conflict began between Burma and the British when the Konbaung Dynasty decided to expand into Arakan in the state of Assam, close to British-held Chittagong in India. After Burma's defeat of the Kingdom of Arakan in 1784–1785, in 1823, Burmese forces again crossed the frontier. This led to the First Anglo-Burmese War (1824–26). The British dispatched a large seaborne expedition that took Rangoon without a fight in 1824. In Danuphyu, south of Ava, the Burmese general Maha Bandula was killed and his armies routed. Myanmar was forced to cede Assam and other northern provinces. The 1826 Treaty of Yandabo formally ended the First Anglo-Burmese War, the longest and the most expensive war in the history of British India. Fifteen thousand European and Indian soldiers died, together with an unknown number of Burmese army and civilian casualties. The campaign cost the British five million pounds sterling to 13 million pounds sterling (roughly $18.5 billion to $48 billion in 2006 US dollars) that led to a severe economic crisis in British India in 1833.
