Sir Thomas Baskerville was appointed commander of the land forces which they carried on board.

Their first design was to attempt Porto Rico, where, they knew, a rich carrack was at that time stationed; but as they had not preserved the requisite secrecy, a pinnace, having strayed from the fleet, was taken by the Spaniards, and betrayed the intentions of the English.

Preparations were made in that island for their reception; and the English fleet, notwithstanding the brave assault which they made on the enemy, was repulsed with loss.
Hawkins soon after died, and Drake pursued his voyage to Nombre di Dios, on the Isthmus of Darien; where, having landed his men, he attempted to pass forward to Panama, with a view of plundering that place, or, if he found such a scheme practicable, of keeping and fortifying it.

But he met not with the same facility which had attended his first enterprises in those parts.

The Spaniards, taught by experience, had every where fortified the passes, and had stationed troops in the woods, who so infested the English by continual alarms and skirmishes, that they were obliged to return, without being able to effect any thing.
