Major Owen Sweet's campaign against prostitutes began shortly after his arrival in Jolo, in the southern Philippines, in May 1899. The situation was urgent. Four months into a war against the Philippine Republic, the 23rd Infantry had taken control of the area from Spanish forces, but, as Sweet lamented, his troops had fallen “heir to the lax moral conditions incident to the Philippines and Oriental countries generally.” Lacking barracks space, his soldiers had been forced to live “in close contact” with “mixed races,” and Sweet had been “confronted with the same status of immoralities and the lawless community” as commanders had in Manila, Iloilo, Cebu and elsewhere. A “personal” investigation in November involving a “house to house examination and inspection” had revealed gambling houses, grog-shops, saloons, “joints where the vilest drugs were dispensed,” and “several resorts of prostitution” inhabited primarily by Chinese and Japanese, but also Filipinos, Moros, and “other immoral women scattered throughout the villages.” Sweet feared that these conditions might spark local tensions, opening a second, Muslim-American front that the Americans could not afford.
