12 Pieces of Tech That Turned the Tide At Normandy

The Allied Invasion of Normandy was one of the single most logistically and strategically complex maneuvers ever concocted by the US military. With a strike force numbering in the hundreds of thousands and the momentum of the entire counter-offensive hanging in the balance, there was simply no room for failure.

In The Americans on D-Day, author Martin K.A. Morgan guides readers from the run up to the invasion through to its horrific aftermath with the help of hundreds of gorgeous sepia-toned archival images.

U.S. Army soldiers use a Jeep to move a Very Low Altitude (VLA) antiaircraft balloon during a training exercise in southern England before D-Day. The VLA balloon could be moored to the ground or to a ship by a heavy mooring cable, but its lift was not particularly strong, so it could be moved using the method depicted here. The VLA balloon provided a simple yet effective means of preventing enemy aircraft from conducting strafing or dive bombing attacks.

This view of the engineer depot at Thatcham, Berkshire, shows some of the different types of construction vehicles being amassed in England prior to the invasion. Here, Allis-Chalmers HD10W tractors, Caterpillar D4 tractors, and Caterpillar D7 bulldozers can be seen parked together in anticipation of the journey toward Germany.

Perhaps the best remembered aspect of the Operation Fortitude deception effort that preceded D-Day was the inflatable Sherman tank. By populating phony marshaling areas with these decoys, the Allies could trick German photoreconnaissance interpreters into believing they were assembling armored forces in areas of England where they were not actually doing so. The overall objective of this subterfuge was to "induce the enemy to make faulty strategic dispositions of forces."

LCVPs from the Coast Guard attack transport USS Samuel Chase (APA-26) land assault troops from the 16th Infantry Regiment, 1st Infantry Division on the Easy Red sector of Omaha Beach on D-Day morning. The area in the background is the stretch of bluff between Exit E-1/ Widerstandsnest 64 and Exit E-3/Widerstandsnest 62. After the war, the Normandy American Cemetery would ultimately be established on top of the plateau seen here. U.S. Coast Guard Collection in the U.S. National Archives 26-G-2337

U.S. Coast Guard–manned LST-21 transfers supplies onto the Rhino that would ferry the load to the beach. This landing ship would support the initial British landings off of Gold Beach on June 6, 1944, and thereafter continue to supply Allied forces along the Normandy coast.

LST-325 (right) and LST-388 (left) unload on Utah Beach at low tide on June 12, 1944, with barrage balloons deployed overhead. This method of delivering cargo was critical during the opening days of the invasion while the two Mulberry temporary harbors were being assembled. Note the sand ramp that has been built to facilitate unloading through the bow doors at low tide. Official U.S. Navy photograph, now in the collections of the National Archives 80-G-252796

Note the Dodge WC54 1/2-ton 4x4 Field Ambulance at the left and the wide variety of landing craft on the beach (including an LCI, an LCT, three LCMs, and three LCVPs).

A view of the Fox Green sector of Omaha Beach overlooking the E-3 beach exit as seen from Widerstandsnest 61 on (probably) June 9. In this photograph, ten LSTs are taking advantage of the low tide to land vehicles directly on the beach, as they would continue doing for several months to come. Among identifiable ships present are LST-532 (in the center of the view); LST-262 (the third LST from the right); LST-310 (the second LST from the right); LST-533 (partially visible on the far right); and LST-524. Note the abundance of barrage balloons overhead and the "half-track" convoy forming up on the beach. LST-262 was one of ten Coast Guard–manned LSTs that participated in the invasion.

Dodge WC-54 3/4-ton ambulances from the 546th Medical Ambulance Company land on the Easy Red sector of Omaha Beach from LCT-550 on Monday, June 12, 1944. The lead ambulance is equipped with an extended air intake/snorkel for fording deep water. The 546th was one of the most important companies supporting the U.S. Army's XIX Corps during combat operations in Normandy.
