She prepared a large fleet of a hundred and twenty sail, of which seventeen were her own ships, forty-three were smaller vessels, and the rest tenders and victuallers: she embarked on board this fleet five thousand new-levied soldiers, and added a thousand veteran troops, whom Sir Francis Vere brought from the Netherlands.

The earl of Essex, commander-in-chief both of the land and sea forces, was at the head of one squadron; Lord Thomas Howard was appointed vice-admiral of another; Sir Walter Raleigh of the third: Lord Mouatjoy commanded the land forces under Essex: Vere was appointed marshal: Sir George Carew lieutenant of the ordnance, and Sir Christopher Blount first colonel.

The earls of Rutland and Southampton, the Lords Grey, Cromwell, and Rich, with several other persona of distinction, embarked as volunteers.

Essex declared his resolution either to destroy the new armada which threatened England, or to perish in the attempt.
This powerful fleet set sail from Plymouth; but were no sooner out of harbor than they met with a furious storm, which shattered and dispersed them; and before they could be refitted, Essex found that their provisions were so far spent, that it would not be safe to carry so numerous an army along with him.

He dismissed, therefore, all the soldiers, except the thousand veterans under Vere; and laying aside all thoughts of attacking Ferrol or the Groine, he confined the object of his expedition to the intercepting of the Indian fleet which had at first been considered only as the second enterprise which he was to attempt.
The Indian fleet in that age, by reason of the imperfection of navigation, had a stated course, as well as season, both in their going out and in their return; and there were certain islands at which, as at fixed stages, they always touched, and where they took in water and provisions.
