World War II Sea War, Vol 9

This volume covers day-to-day naval actions during March-June 1943. The Allies attacked German U-boats day and night, forcing their withdrawal from the vital North Atlantic convoy routes, clearing the way for the eventual invasion of Europe from Britain. In the Bismarck Sea, Allied aircraft destroyed an entire Japanese troop convoy bound for New Guinea. In the Komandorski Islands, the U.S. Navy engaged a superior Japanese force and out fought them. After this loss, the Japanese commander was fired in disgrace. The Allies isolated the German and Italian troops fighting in Tunisia with an air and sea blockade. Without support from Italy, Tunisia fell. U.S. aircraft ambushed Japanese Admiral Yamamoto while he was en route to an inspection visit in the Solomon Islands. The U.S. 7th Infantry Division liberated Attu Island in the Aleutian Islands.
