On the evening of 22 October the Anglo-Dutch fleet entered the Ria de Vigo, and sailed past the two forts of the city of Vigo that fired at them as they passed by. At the end of the bay the French fleet and Spanish treasure ships lay in the harbour of Redondela, surrounded by the Galician mountains. Château-Renault had taken charge of the defensive measures, and had blocked the narrow entrance, across the Rande Strait, with a boom made largely of timber and chain tightly bound together. At the north end of the boom was positioned a gun battery which, according to Rooke's journal, comprised "fifteen or sixteen" guns; at the south end sat Fort Rande sitting a little way up from the sea, consisting of a strong stone tower with platforms constructed for cannon. The space between the tower and the water's edge consisted of a fortified enclosure, at the bottom of which stood a battery commanding the straits. In total, the Rande fortifications had been armed with more than 30 guns. To supplement the French troops from the fleet, a number of levies were raised by the Prince of Barbançon, governor and captain-general of Galicia.
