During the Musket Wars (1820s—1830s), Māori warriors used Brown Besse's purchased from European traders at the time. Some muskets were sold to the Mexican Army, which used them during the Texas Revolution of 1836 and the Mexican–American War of 1846 to 1848. Brown Besses saw service in the First Opium War and during the Indian rebellion of 1857. Zulu warriors, who had also purchased them from European traders, used them during the Anglo-Zulu War in 1879. One was even used in the Battle of Shiloh in 1862, during the American Civil War.
