Yuma War
The Yuma War was the name given to a series of United States military operations conducted in southern California and what is today southwestern Arizona from 1850 to 1853. The Yumans were the primary opponent of the United States Army, though engagements were fought between the Americans and other native groups in the region. Conflict generally took the form of guerrilla warfare, and, over the course of three years, the army engaged in pursuing unfriendly natives, protecting American settlers crossing the Colorado River and preventing conflict between the native tribes. A peace treaty in summer of 1853 was signed, ending hostilities between the Yuma and the United States, but it sparked a short war between the Yuma and the Cocopah. During the conflict, the historic Fort Yuma was constructed and became an important outpost on the frontier.
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.
