Davis raided and stole £25,000 in jewels and silver from the city of Zaña, Peru in March 1686. Although later raids yielded smaller wealth, 39 African slaves were liberated from Paita and later joined the expedition. Raiding five more towns between the months of May and June, including the failed attack on La Serena, many priests and officials were killed attempting to hide the city's treasury until the defenders of Pisco agreed to pay £5,000 in ransom. Davis continued with 80 men and looted £10,000 from Arica, Chile in February 1687. Learning from captives of Spanish plans to send a squadron from Peru against Captain Pierre le Picard, he arrived at Guayaquil in May and helped defeat the fleet and split £50,000 with the French buccaneer. Leaving Guayaquil on June 12, Davis stopped at the Galápagos Islands and Juan Fernández Islands and also supposedly sighted Davis Land while making his way down to Cape Horn, on his return voyage to the American colonies.
