Bougainville Strait

Bougainville Strait separates Choiseul Island from Bougainville Island, the next to the northward. It was first passed through in 1768 by Louis Antoine de Bougainville, who christened it. A Lieutenant John Shortland of the Royal Navy sailed through it in 1788, giving the name of Treasury Islands to the numerous islands, lying in the strait. He named the strait after himself, but it became known as Bougainville in the future.
