The Battle of Karavia Bay occurred in February 1944 and was the first surface engagement fought in the Rabaul area of New Britain during the Solomon Islands Campaign. A squadron of United States Navy warships attacked the harbor defenses of Karavia Bay and exchanged naval gunfire and torpedoes with two Japanese destroyers. The nighttime engagement ended with the silencing of the Japanese artillery and resulted in a blockade of the port. Two Japanese transports were also sunk in the fighting. Later, Allied forces landed on the island and destroyed the enemy garrison.
