On the outgoing voyage, da Gama's fleet opened contact with the East African gold trading port of Sofala and reduced the sultanate of Kilwa to tribute, extracting a substantial sum of gold. On reaching India in October 1502, da Gama's fleet set about capturing any Arab vessel he came across in Indian waters, most notoriously the Miri, a pilgrim ship from Mecca, whose passengers he massacred in open water. He then appeared before Calicut, demanding redress for the treatment of Cabral. While the Zamorin was willing to sign a new treaty, da Gama made a call to the Hindu king to expel all Muslims from Calicut before beginning negotiations, which was turned down. The Portuguese fleet then bombarded the city for nearly two days from the sea shore, severely damaging the unfortified city. He also captured several rice vessels and cut off the crew's hands, ears and noses, dispatching them with an insulting note to the Zamorin.
