In November, it moved to Sardinia, to strike Axis targets in central Italy. Early in 1944, the squadron supported Allied ground forces as they advanced in the Cassino and Anzio areas. Later in the year, the group attacked German supply lines in northern Italy, bombing bridges, marshalling yards, and roads. During the summer, it bombed bridges over the Po River in northern Italy to block the stream of German supplies and reinforcements going southward. The unit supported the invasion of southern France in August 1944 by attacking coastal batteries, radar stations, and bridges. From Corsica, it hit railroad bridges in Northern Italy and late in the year attacked railroad lines through the Brenner Pass that connected Germany and Austria with Italy.
