On the advice of Hogstraten an expedition was now organized against the island of _Itamaraca_, on which the enemy had to rely for grain. After three attacks, the assailants, under Fernandes and Vidal, forced their way into the town, and had actually secured their victory, when it was lost through their rapacity and cruelty. The troops from _Bahia_ showed an example of plundering which was not thrown away upon the Dutch deserters of Hogstraten’s regiment; and Cardozo had given orders to put all the Indians to the sword, the result being that the Portuguese had to retire with loss and disgrace. They, however, fortified _Garassu_, and secured all the roads by which the enemy from _Itamaraca_ could molest them. For some time after this expedition the Portuguese were kept inactive by a strange infectious disease, which seemed only to yield to the treatment of bleeding, and which filled the hospitals, until Joam Fernandes hit upon the expedient of setting up certain images of saints, before whom mass was daily performed. To their intercession the cessation of the scourge was ascribed. At the same time that the main body of the Portuguese insurgents were suffering from this cause, their countrymen in _Rio Grande_ were massacred by the _Tapuyas_, in revenge for the execution of the Indians at _Serinhaem_. This slaughter had, however, the effect of convincing the Portuguese who had not yet taken up arms of the uselessness of neutrality. Meanwhile the action of the two forces at _Recife_ was confined to isolated attacks, the besiegers not being provided with the means either of properly besieging the place or of blockading it. Every day or night witnessed some sally or skirmish, and many dashing but unimportant deeds are recorded. The general conviction, however, gained ground that the Portuguese would eventually win the day; and many slaves deserted to them whilst there was still some merit to be gained by doing so. The Dutch at this time hoped to effect a diversion in their favour by means of Hogstraten’s regiment of deserters. Although he himself was a traitor beyond redemption, it was rightly believed that most, if not all, of his men had taken service with the Portuguese on compulsion, and would be glad of an opportunity to return to their natural service. In this belief, communication was opened with the regiment; and it was arranged that a sally was to be made from the city in order to facilitate their desertion. This measure was only thwarted by a chance movement of the Portuguese commander. The backwardness of the would-be deserters, however, could not escape notice. Their captain, named Nicholson, demanded an opportunity of clearing their fame, which, being granted, he and seventy of his men succeeded in effecting their purpose, and reached _Recife_ in safety. After this, the remaining Dutch were disarmed and sent to _Bahia_.
