 Spanish forces were entrenched on the crest of two small hills, between which the road from Arroyo to Guayama ran. The Americans had crossed a stream in front of the hills when suddenly the Spanish opened fire. The Americans protected their position by the stream and increased their firepower as more reinforcements arrived. The outnumbered Spanish troops retreated to Guayama as the Americans made their advance on the hills. The firefight, which lasted half an hour, left three American wounded. When the 4th Ohio entered the town they discovered that the Spaniards had fled north and abandoned the city, ending the Battle of Guayama. General John Rutter Brooke used the Cautiño Residence (Casa Cautiño) by the town square in Guayama as his military headquarters.
