Proceeding under orders from Rear Admiral
William T. Sampson, the monitors , , the armed tug , and the collier proceeded from
Port Nipe to Cape San Juan, on the northeastern tip of
Puerto Rico, arriving late afternoon on August, 1. The ships anchored behind a series of keys:
Icacos, Isla de Lobos and
Isla Palominos, out of sight from the mainland. Cape San Juan (
Fajardo) was the designated landing site for the US Army forces under Major General
Nelson A. Miles. However, sometime between July 21–24, 1898, Miles had unilaterally changed the invasion site from
Fajardo to
Guanica on the southwest coast of Puerto Rico. Expecting a rendez-vous with Miles' troops, but finding no transports save for
Arcadia and
Mississippi that "had been ordered to make a landing, but were at a loss what to do", the senior officer present, Captain
Frederick W. Rodgers, USN, of
Puritan ordered
Leyden, Ensign
Walter S. Crosley, USN, commanding, to stand out for the telegraph office at
St. Thomas to communicate with the Navy Department in Washington, D.C. Rodgers ordered two boat parties of
bluejackets ashore from
Puritan led by Lt. Herman G. Dresel, USN, for reconnaissance. The sailors traveled to within half a mile of the nearby town of
Fajardo. Upon spotting Spanish troops, the boat party turned back, seizing a schooner as a
Prize of war before returning to
Puritan. The next morning, Captain Rodgers ordered another boat party ashore led by Lt. Commander James R. Selfridge, USN. The sailors seized the "Faro de Las Cabezas de San Juan" (
Cape San Juan lighthouse), posted the American flag and ordered the lighthouse keepers to continue working. The Spaniards in Fajardo, about 5 miles away, did not become aware of the Americans until the early hours of August 3, when an employee of the telegraph office in Fajardo phoned the lighthouse and overheard voices speaking English. This information was immediately telegraphed to Governor General
Manuel Macías y Casado at
La Fortaleza in
San Juan, Puerto Rico. Macias ordered the remaining Spanish troops in Fajardo to withdraw and remove the telegraph equipment. When Dr. Santiago Veve Calzada, an influential Fajardo civic leader, realized that the Spaniards had withdrawn and the city was defenseless against the invading Americans, he entreated the Spanish authorities in San Juan over the next two days to dispatch troops to defend Fajardo. ==Battle==
