 The combined force besieged the fort at Terrenate.After having considerable effect, however, they found themselves without powder and were forced to raise the siege and return to Amboina.On April 30, 1603, a fire started in a little field house used by some Filipinos and Negroes of the native hospital in the city, at three o'clock in the afternoon, and passed to other houses so quickly, with the force of the rather fresh wind, that it could not be stopped.
