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.
Royal Burmese armed forces
Likewise, the Burmese put up the best fight in the First Anglo-Burmese War (1824–1826), the longest and most expensive war in British Indian history. The campaign cost the British five million to 13 million pounds sterling (roughly 18.5 billion to 48 billion in 2006 US dollars), and 15,000 men. But for the Burmese, it was the beginning of the end of their independence. Not only did they lose their entire western and southern territories by the Treaty of Yandabo, a whole generation of men had been wiped out on the battlefield. After 30 years of growing technology gap, the outcome of Second Anglo-Burmese War (1852) was never in doubt. Lower Burma was lost. Another three decades later, the Third Anglo-Burmese War (1885) lasted less than a month. The entire country was gone.
