Azores Voyage of 1589

The Azores Voyage of 1589, also known as Cumberland's Third Voyage, was a series of conflicts in the Azores islands between August and September 1589 by an English military joint stock expedition led by George Clifford, 3rd Earl of Cumberland, during the Anglo–Spanish War. All the islands were attacked either for provisions or the attainment of Spanish and Portuguese prizes. A number of Portuguese and Spanish ships were captured and also included a battle at Faial which resulted in the capture of the fort and the main town, which was subsequently sacked and burned. The English were able to return home unmolested with a total of thirteen prizes – the expedition was a success and with a good profit for the investors although many people died to disease and storms.

The expedition was also a scientific one in that the eminent mathematician and cartographer Edward Wright carried out navigational studies that, for the first time, explained the mathematical basis of the Mercator projection.
