organize the defence of the island against the Spanish. By using the tactic of attacking instead of defending, he sent out Christopher Myngs to raid Spanish colonial cities and bases. Tolú and Santa Marta were among them in 1658 and the following year Cumana, Puerto Caballos and Coro were plundered and devastated and Myngs returned to Jamaica with a vast amount of plunder and treasure. Naval war In April 1656 English Admiral Robert Blake with a fleet of around forty warships, fireships and supply vessels sailed to blockade the Spanish port of Cadiz which continued throughout the summer. The Spanish remained on the defensive and took no aggressive action against the English fleet. In mid-June, Captain Edward Blagg sailed with eight ships to raid ports in northern Spain. On 24 June, Blagg raided Vigo, where a number of ships in the harbour were destroyed. While Blake replenished his water supplies on the African coast, a detachment of five frigates under a Captain Smith raided Malaga in southern Spain on 19 July. Smith sank nine Spanish ships, spiked the harbour guns and bombarded the town. A similar raid on Alicante was unsuccessful, but the threat of attack disrupted trade all along the coasts of Spain. On the evening of 8 September, one of Blake's captains, Richard Stayner, intercepted a Spanish treasure fleet and captured or sank all but two of its ships. The loss of the cargoes of the ships captured or sunk by the English was a serious blow to the economy of Spain with an estimated loss of £2,000,000. For the first time in naval history, Blake kept the fleet at sea throughout an entire winter in order to maintain the blockade against Spain. In February 1657, Blake received intelligence that the plate fleet from New Spain was on its way across the Atlantic. Leaving two ships to watch Cadiz, Blake sailed from there to attack the plate fleet, which had docked at Santa Cruz on Tenerife in the Canary Islands to await an escort to Spain. In April in the Battle of Santa Cruz de Tenerife, Blake completely destroyed the Spanish merchant convoy—the West Indian Fleet—however, the fleet had landed the bullion before the battle. Blake was unable to seize it, but it was also unavailable to the government in Madrid. The short-term effect of Blake's blockade of Spain and his victory at Santa Cruz was the disruption
