Final answer:
The claim that the U.S. was quickly defeated by Filipino rebels is false. The Philippine Insurrection from 1899 to 1902 saw high casualties and harsh conflict, but the U.S. retained control until Philippine independence in 1946.
Step-by-step explanation:
The statement that the Filipinos quickly defeated the U.S. is false. During the Philippine Insurrection, which took place between 1899 and 1902, the Filipinos led by Emilio Aguinaldo sought independence and took up arms against American forces. Despite their valiant efforts, their attempts at conventional warfare failed and they resorted to guerrilla tactics.
The conflict resulted in a high number of casualties on both sides, with civilian deaths reaching as high as 250,000 due to harsh tactics employed by the U.S.
forces, such as the destruction of villages and the use of concentration camps. Major combat operations largely ceased by 1901, but the Philippines did not gain its independence from the United States until much later, in 1946.
