It was formed on December 24, 1898, after General Otis received permission from the United States Department of War to accept the surrender of the Spanish garrison of Iloilo City. The brigade left Manila on December 26 and arrived outside the city abroad the cruiser USS Baltimore on the morning of the 28th to discover insurgents had already occupied the city.
