At Flores Island the English fleet was surprised by a much larger squadron sent by King Philip II of Spain. Howard retreated to safety, but Grenville faced the 53 enemy ships alone, leading his single ship in what amounted to a suicide mission, stating that he "utterly refused to turn from the enimie...he would rather chose to die than to dishonour himselfe". His crew was reduced by nearly 100 men due to sickness on shore, but he chose nonetheless to confront the far superior Spanish force. For twelve hours he and his crew fought-off the Spanish, causing heavy damage to fifteen galleons. According to Raleigh's account, Grenville and his soldiers fought for hour after hour, "…until all the powder of The "Revenge", to the last barrell, was now spent, all her pikes broken, fortie of her best men slain, and the most part of the rest hurt". The ship itself was "marvellous unsaverie, filled with bloud and bodies of deade and wounded men like a slaughter house".
