Is it true that the us forces fought a guerrilla war in the Philippines after the Treaty of Paris?

Yes, it is true that U.S. forces engaged in a guerrilla war in the Philippines after the Treaty of Paris in 1898, which ended the Spanish-American War. The treaty resulted in the U.S. acquiring the Philippines, leading to the Philippine-American War (1899-1902) as Filipino nationalists resisted American control. Guerrilla warfare tactics were employed by Filipino fighters against U.S. forces, leading to a protracted and brutal conflict. The war officially ended in 1902, but sporadic resistance continued for several years.
