The 321st Bombardment Group, USAAF, was a B-25 group that fought in North Africa, Sicily, Italy and southern France, sinking the battleship Strasbourg during that campaign.
By the autumn of 1942 the 321st had been allocated to the forces that were to cross the South Atlantic to join Operation Torch. The group was to cross with 57 B-25s and was expected to arrive on D+60.
Aircraft started to reach Florida in mid-February 1943, to cross the Atlantic via Ascension Island and Accra. The group reached western Africa in February 1943 and moved up the coast to Marrakech and then into the theatre of action. The group joined the Twelfh Air Force and took part in the campaign in Tunisia.
The group entered combat in the second half of March 1943. Its main targets for the rest of the war would be transport links (marshalling yards, rail, road, bridges, viaducts, shipping and harbours) or enemy troop concentrations or gun emplacements. It would operate against targets in North Africa, France, Sicily, Italy, Bulgaria, Yugoslavia and Greece over the next two years.
The group received two Distinguished Unit Citations. The first was for an attack on a German airfield near Athens on 8 October 1943, carried out in the face of heavy German anti-aircraft fire and fighter defences.
Between March and May 1943 the group operated against targets in North Africa. In May-June the group took part in the massive bombing campaign that overwhelmed the defenders of the islands of Pantelleria and Lampedusa.
In July 1943 the group supported the invasion of Sicily. In September it took part in the fighting at Salerno, which took place just as the group began to move to Italy.
Between January and June 1944 the group supported the advance towards Rome. The group became something of an expert at bridge breaking, difficult narrow targets.
In August the group supported Operation Dragoon, the invasion of southern France. On 18 August thirty six B-25s from the group sank the battleship Strasbourg, a cruiser and a submarine to prevent the Germans from using their guns against the forces attacking Toulon. The group received its second DUC for this raid.
After the fighting in France moved out of range of the medium bombers the group returned to the fight in Italy, and it operated against targets in northern Italy from September 1944 until the end of the war.
The group was inactivated in Italy on 12 September 1945.
