Paucarpata Arequipa Peru

The Chilean government had prepared an expedition to put a quick end to the conflict, sending a fleet carrying an expeditionary force of approximately twenty-eight huidred troops under the command of Admiral Manuel Blanco Encalada and British commander Robert Simpson in September 1837.

The Chilean army had landed at Islay in southern Peru in October 1837, occupying the city of Arequipa after a long and arduous march, during which the Chileans had been decimated by disease.

The invading army fails to find the local support that it had been led to believe it would encounter against the Confederate government.

While Admiral Blanco Encalada is immersed in endless negotiations with the local leaders, Santa Cruz quietly surrounds the city with his army and effectively blockades the invading army inside.

Surrounded and out-maneuvered, and following an encounter at Paucarpata with an army under the command of Santa Cruz, Encalada is forced to sign the Treaty of Paucarpata on November 17, 1837.

He agrees to the devolution of all captured ships by Chile, the restoration of commercial relations between both nations, the withdrawal of all Chilean troops from Confederate territories and the payment by the Confederacy of the former Peruvian foreign debts with Chile.

The Chilean troops are reembarked.
