Em 15 e 16 de março de 1889, o ciclone de Apia destruiu todos os seis navios de guerra estadunidenses e alemães no porto, encerrando o impasse. O Calliope conseguiu escapar do porto e sobreviver à tempestade. Robert Louis Stevenson testemunhou a tempestade e suas consequências em Apia e mais tarde escreveu sobre o que viu.[1] A guerra civil samoana prosseguiu, envolvendo estadunidenses e alemães, o que resultou, por meio da Convenção Tripartite de 1899, na partição das Ilhas Samoanas em Samoa Americana e Samoa alemã.[2]
