BAP Manco Cápac The monitor was renamed by the Peruvian Navy as Manco Cápac, after Manco Cápac, the legendary first king of the Kingdom of Cuzco which would grow into the Inca Empire. To prepare the ship for her lengthy voyage to Peru around Cape Horn, Swift & Co. added a breakwater on the bow, stepped two masts with a fore-and-aft rig to supplement her engine, and provided closures to make vents and deck openings water tight. While this was going on, the United States was negotiating with Great Britain over compensation for losses inflicted by British ships knowingly sold to the Confederacy during the Civil War (the Alabama Claims). Peru had been involved in an undeclared war with Spain (the Chincha Islands War) in 1864–66 and the US was not willing to prejudice its claims against the United Kingdom by performing a similar action for a belligerent power. Negotiations over the issue delayed the departure of the two monitors until January 1869, after Peru bought two steamers, Reyes and Marañon to tow the monitors. They only reached Pensacola, Florida, before machinery breakdowns forced them to wait 30 days for repairs to be completed. En route from Key West to the Bahamas, the ships were separated in heavy weather. When Reyes attempted to reattach her towrope after the storm moderated, she collided with the sharp bow of Manco Cápac and sank in 15 minutes. The monitor, short of coal and food, was forced to make port at Naranjo, Cuba, then held by rebels against the Spanish government. They allowed the ship to restock her supplies, but no coal was available so the crew loaded up enough wood to reach the Bahamas where they were able to send a local schooner to Nassau to inform the authorities of their plight. The ships finally reunited at St. Thomas in the Virgin Islands and had to wait for the Pachitea to arrive from Peru to tow Manco Cápac. While entering Rio de Janeiro on the night of 15 September, Manco Cápac ran aground; she was refloated the following day, but the damage required three months to repair. The ships were joined by the steam corvette during this time. They reached the Strait of Magellan on 29 January 1870 and Callao on 11 May. In 1879, disagreements over guano and nitrate-rich lands led Chile to start the War of the Pacific with Bolivia and
