On the 25th April the army, having crossed the mouth of the West Scheld, from Zeeland, in numberless vessels of all sizes and degrees, effected their debarkation on the island of Cadzand.
In the course of two days they had taken possession of the little town, and all the forts of that island, having made their entrance through what was called the Black Channel. Had they steered boldly through the Swint or Sluys channel at once, it is probable that they might have proceeded straight up to Sluy’s, and taken the place by surprise. Maurice’s habitual caution was, perhaps, on this occasion, a disadvantage to him, but he would have violated the rules of war, and what seemed the dictates of common sense, had he not secured a basis of operations, and a possibility of retreat, before plunging with his army into the heart of a hostile country. The republic still shuddered at the possible catastrophe of four years before, when circumstances had forced him to take the heroic but dangerous resolution of sending off his ships from Nieuport. Before he had completed his arrangements for supplies on the island of Cadzand, he learned from scouts and reconnoitring parties that Spinola had sent a thousand infantry, besides five hundred cavalry, under Trivulzio, to guard the passage across the Swint. Maurice was thus on the wrong side of the great channel by which Sluy’s communicated with the sea?
The town of Sluy’s and its situation have been described in a former chapter. As a port, it was in those days considered a commodious and important one, capable of holding five hundred ships. As a town, it was not so insignificant as geographical and historical changes have since made it, and was certainly far superior to Ostend, even if Ostend had not been almost battered out of existence. It had spacious streets and squares, and excellent fortifications in perfectly good condition. It was situate in a watery labyrinth, many slender streams from the interior and several saltwater creeks being complicated around it, and then flowing leisurely, in one deep sluggish channel, to the sea. The wrath of Leicester, when all his efforts to relieve the place had been baffled by the superior skill of Alexander Farnese, has been depicted, and during the seventeen years
