led the attack at Santa Cruz de Tenerife In 1654, the
Commonwealth of England decided to support
France in
its war with
Habsburg Spain. This intervention was mostly motivated by hopes to profit from the war through attacks on the
Spanish West Indies. War was openly declared in October 1655 and endorsed when the
Second Protectorate Parliament assembled the following year. An English
attempt to capture the
Spanish colony of Santo Domingo failed, however, whereupon the English shifted their attention to Europe. One of the prime enterprises became the blockade of
Cádiz, which had not previously been attempted on such a scale. Robert Blake was to be in charge and also was to come up with methods that he had used in his previous encounters with the Dutch and Barbary pirates. Blake kept the fleet at sea throughout an entire winter in order to maintain the blockade. During this period a Spanish convoy was
destroyed by one of Blake's captains,
Richard Stayner. A further six ships were sent from England as reinforcements towards the end of 1656, including , which became Blake's
flagship. In February 1657, Blake received intelligence that
the convoy from Mexico was on its way across the Atlantic. Although his captains wanted to search for the Spanish
galleons immediately, Blake refused to divide his forces and waited until victualling ships from England arrived to re-provision his fleet at the end of March. After this Blake (with only two ships to watch Cádiz), sailed from
Bay of Cádiz on 13 April 1657 to attack the plate fleet, which had docked at Santa Cruz de Tenerife in the Canary Islands to await an escort to Spain. Blake's fleet arrived off Santa Cruz on 19 April. Santa Cruz lies in a deeply indented bay and the harbour was defended by the
Castle of San Cristóbal (Santa Cruz de Tenerife), armed with forty guns and a number of smaller forts connected by a triple line of breastworks to shelter musketeers. In an operation similar to the
raid on the Barbary pirates of
Porto Farina in Tunisia in 1655, Blake planned to send twelve frigates under the command of Rear-Admiral Stayner in into the harbour to attack the galleons while he followed in
George with the rest of the fleet to bombard the shore batteries. ==Battle==
