In the north of the colony the new situation led to a somewhat curious and paradoxical state of affairs. The Dutch had overrun Northern Brazil for the sole ostensible reason that it was a possession of Spain. Now that Portugal had freed herself from Spain, and that Brazil in consequence was once again a purely Portuguese possession, all reason for the Dutch occupation of the coast of Brazil was at an end. In Europe the situation was this: The Dutch and the Spaniards had been for generations at deadly enmity, while the rivalry between the Portuguese and the Spaniards had induced a hostility rather less deadly, it is true, but, nevertheless, sufficiently keen for the purposes of war. Thus, with the freedom of Holland from Spain, and with the liberation of Portugal from Spain, the situation of the two, once vassal countries, was identical. They had an interest in common in preserving themselves from the rapacity of Spain.
This was all very well in Europe, but in South America matters worked out very differently in actual practice. The Dutch were now firmly established in Northern Brazil, having their headquarters at the town of Recife, or Pernambuco. It was not in human nature to give up the fruits of their conquest merely because the Portuguese had driven out the Spanish officials from their territories in Europe. The situation from the point of view of Holland was simple, and could be put in a nutshell. The Dutchmen were willing enough to enter into friendly relations with the Portuguese, but not at the cost of the Brazilian possessions of the Dutch West Indian Company, which had been especially formed for the purpose of acquiring these.
Count Mauritz of Nassau had proved himself an able administrator, and it was now the turn of the Dutch to intrigue where before they had fought openly. In June, 1641, an agreement was negotiated in Europe between Portugal and the United States of the Netherlands, which concluded a truce for ten years. A year was allowed in order to carry this intelligence to the Dutch commanders in South America and elsewhere. In order to cement this new friendship, the Dutch further agreed to supply Portugal with arms and ammunition to aid in the common fight against Spain.
The Brazilian policy of Holland was, however, quite different from that proposed in Europe. Instructions were sent to Count Mauritz of Nassau ordering him to continue in the command, to extend the sphere of the Dutch dominion, and, if possible, to capture Bahia. These instructions were largely due to the belief held in Holland that Portugal would be unable to maintain her independence for any length of time.
When the news of the truce was first brought to Count Mauritz at Recife, all the outward marks of festivity and great rejoicings were exhibited. A general fraternization ensued, and the late enemies and temporary friends regaled each other at various banquets. Thus Paulo da Cunha, the Brazilian patriot, upon whose outlawed head the Count had put a price of 500 florins (to which da Cunha had retorted by placing a price of 2,000 cruzados upon the Count's), was now invited to feast with Nassau, and the two entered into an intimate and rather chaffing discussion upon the respective prices they had put upon each other's heads.
Very shortly, however, the Brazilians found reason to suspect the sincerity of the Dutch professions of friendship. A Dutch fleet sailed north, captured São Christovão, and in other places seized a number of Portuguese vessels. The Portuguese now found themselves in something of a dilemma, owing to the very fact of the independence they had won. During the Spanish dominion the ports had been manned by the Spaniards as well as by the Portuguese. This, of course, was no longer the case. Bahia, for instance, had now lost a great part of its garrison. The 700 Spaniards and Neapolitans who had served there were honourably treated by the Portuguese, and were sent on their way to Europe, but were captured by the Dutch ere they had left the coast.
The Dutch aggression, as a matter of fact, was not confined to South America. A Dutch force of 2,000 regular troops had entered São Paul de Loanda, the capital of Angola. The loss of this important Portuguese possession on the west coast of Africa produced a direct effect on South America, for it was from here that the Brazilians had imported all their African slaves. Thus the whole of this traffic passed entirely into the hands of the Dutch for the time being. Mauritz of Nassau went the length of suggesting that the territory of Angola should become an appendage of that of Dutch Brazil, as the two were bound so closely by this traffic! The Dutch had also captured the Island of St. Thomas. In that place, however, the climate avenged the Portuguese to the full, and the mortality among the Dutch from fever in this island was appalling.
The Dutch in Brazil now sent an expedition to the north to obtain possession of the Province of Maranhão. They captured and plundered the capital, pillaging churches and ransacking the sugar factories. The Governor, Maciel, appears to have behaved very badly, and with no little treachery towards his fellow-countrymen. Nassau, when Maciel surrendered, treated him with contempt, and imprisoned him. The situation had now become grimly farcical. In Europe the Dutch were supplying the Portuguese with arms and stores, and acting in general as their allies; while in Brazil the two nations were openly at war, and the Dutch were sending hostile expeditions in all directions!
Just at this period, indeed, the ambition of the Dutch appeared to swell to the highest point. Count Mauritz determined to push his conquests far to the south, and had even prepared an expedition for the capture of the Spanish town of Buenos Aires; but the attempt was frustrated by the hostility of the Portuguese and Indians nearer home. All this time, of course, Dutch fleets had been harrying the Pacific coast, and the Dutch had actually obtained a footing in Southern Chile, although this was not destined to prove permanent. With the extension of their boundaries, however, it was but natural that the difficulty of preserving their dominion should increase.
