The Northwest Passage is a sea route connecting the Atlantic and Pacific Oceans through the Arctic Ocean. Interest kindled in 1564 after Jacques Cartier's discovery of the mouth of the Saint Lawrence River, Martin Frobisher had formed a resolution to undertake the challenge of forging a trade route from England westward to India. In 1576 - 1578, he took three trips to what is now the Canadian Arctic in order to find the passage. Frobisher Bay, which he discovered, is named after him. On August 8, 1585, under the employ of Elizabeth I the English explorer John Davis entered Cumberland Sound, Baffin Island. Davis rounded Greenland before dividing his four ships into separate expeditions to search for a passage westward. Though he was unable to pass through the icy Arctic waters, he reported to his sponsors that the passage they sought is "a matter nothing doubtful , and secured support for two additional expeditions, reaching as far as Hudson Bay. Though England's efforts were interrupted in 1587 because of Anglo-Spanish War, Davis's favorable reports on the region and its people would inspire explorers in the coming century.
