During the Spanish-American War (1898), a number of Spanish soldiers drowned in this river:[2] I overtook him Saturday morning about three and one-half miles north of Las Marias.

His infantry had pulled his guns over roads that were almost perpendicular.

His troops were exchanging shots at long range across a deep valley with the retreating Spaniards, most of whom had forded (losing a lot of men, who were drowned) a deep and rapid river known in that country as the Rio Prieto.

Our fire had already demoralized the thoroughly disheartened and half-famished Spanish soldiers; and their rear-guard, at least, was also disorganized and hiding in the hills.
