The successes of 1628 had the effect of encouraging the directors to try to retrieve the failure at Bahia by conquest elsewhere.
Olinda, on the coast of Pernambuco, was selected as the new objective. An expeditionary force of exceptional strength was got ready; and, as Piet Hein, at the very height of his fame, unfortunately lost his life in the spring of 1629 in an encounter with the Dunkirk pirates, Hendrik Cornelisz Lonck, who had served as vice-admiral under Hein at Matanzas bay, was made admiral-in-chief, with Jonckheer Diederik van Waerdenburgh in command of the military forces. A considerable delay was caused by the critical position of the United Provinces when invaded by the Spanish-Imperialist armies at the time of the siege of Hertogenbosch, but the capture of that fortress enabled the last contingents to sail towards the end of the year; and Lonck was able to collect his whole force at St Vincent, one of the Canary islands, on Christmas Day to start on their voyage across the Atlantic. That force consisted of fifty-two ships and yachts and thirteen sloops, carrying 3780 sailors and 3500 soldiers, and mounting 1170 guns. Adverse weather prevented the arrival of the fleet in the offing of Olinda until February 13. Along the coast of Pernambuco runs a continuous reef of rock with narrow openings at irregular intervals, forming a barrier against attack from the sea. Olinda, the capital of the provinces, was built on a hill a short distance inland, having as its port a village known as Povo or the Reciff, lying on a spit of sand between the mouths of the rivers Biberibi and Capibaribi. There was a passage through the rocky reef northwards about two leagues above Olinda and three others southwards (only one of which, the Barra, was navigable for large ships) giving access to a sheet of water of some 18 ft. in depth between the reef and the spit of sand, and forming a commodious harbour, the Pozo.
The problem before the Dutch commander was a difficult one, for news of the expedition had reached Madrid; and Matthias de Albuquerque, brother of “the proprietor” of Pernambuco, Duarte de Albuquerque, a man of great energy and powers of leadership, had arrived in October to put Olinda and the Reciff into a state of defence. Two forts strongly garrisoned and armed, San Francisco and San Jorge, defended the
