1943: Before dawn, initial Allied landings took place at Salerno, Italy. For these landings, the 12-mile beach was divided into two parts. The north section was invaded by the 46th British Division that landed from tank landing ships with the aid of the 1006th Seabee Causeway Detachment (CBD 1006). The south section was invaded by the American forces that also landed on causeways laid down by Seabee pontoon crews. The Germans, however, were prepared for battle at Salerno. The landing ships carrying the Seabees and their pontoons took a frightful beating. Many pontoon strings were sent ashore and blown up on the mined beaches. Allied ships guarding the beaches were bombed by German guided missiles, dive bombers and torpedoes, and shelled by German submarines and patrol craft. During the first 10 days of battle, the Seabees bivouacked on the Salerno beaches while they unloaded ships, built unloading-slips and roadways, and cleared traffic doing it all while under constant fire. CBD 1006 suffered 28% casualties. Lt. Carl M. Olson, CEC, officer in charge (OIC), CBD 1006, and seven of his men were killed in action during this conflict. The Allies won the battle at Salerno, and Seabee operations were invaluable in the great victory.
