"The wing first saw combat in the invasion of Italy, where its units flew close support missions to stop the German counterattack on the beachhead at Salerno during September 1943.
As the Allied forces progressed, the 42nd took a leading part in interdicting Axis road and rail transport, and later in 1944, in the attacks against the monastery at Cassino.
As the war drew to a close the 42nd attacked German positions along the Siegfried Line and, in support of the Allied forces in their sweep across southern Germany, bombed enemy strong points, and communications and supply facilities.
The division conducted numerous staff assistance visits and simulated no notice inspections, and participated in exercises such as Buy None and Global Shield.
