Question: Of the two bays the USS Lardner operated in, which had the largest land area? Passage:After patrol duty early in October, Lardner returned to escort duty between New Caledonia and the Solomons, then screened task forces operating out of Purvis Bay in the Bougainville Campaign. She bombarded Bougainville on 29 November, and continued occasional bombardments along with escort missions through January 1944. On 14 February, Lardner sailed north with TF 38 to cover initial landings on Green Island, and on the way was attacked by six Aichi D3A "Val" dive bombers. Late in February, the destroyer bombarded Rabaul; searched the Bismarck Sea for enemy shipping; and then attacked Karavia Bay, sinking an enemy cargo ship of the Heito Maru class 25 February. Later that day she bombarded Kavieng, receiving a few shrapnel holes from extremely heavy and accurate enemy return fire. During March and April, Lardner operated with support forces for the Palaus raid, and with escort carriers during the landing at Hollandia, New Guinea.
