The Filibuster War or Walker affair was a military conflict between filibustering multinational troops stationed in Nicaragua and a coalition of Central American armies. An American mercenary, William Walker, invaded Nicaragua in 1855 with a small private army. He seized control of the country by 1856, but was ousted the following year.
