D-Day and Bomber Command
In the early hours of June 6, 1944, 80 years ago, the Allied forces launched the largest amphibious invasion in history, known as D-Day. This monumental operation marked the beginning of the end for Nazi occupation in Western Europe. While the bravery of the ground troops is often highlighted, Bomber Command played an equally crucial role in the success of this operation, both before, during, and after the invasion.
Bombing of German Infrastructure
In the months leading up to D-Day, Bomber Command was tasked with a critical mission: to weaken the German forces in Normandy by targeting and destroying key infrastructure. This involved extensive bombing raids on transport networks, industrial facilities, and airfields to disrupt German reinforcements.
Bomber Command dropped over 5,000 tons of explosives on beach defences around Normandy. On the nights of June 5th and 6th, Bomber Command flew 1,211 sorties in support of the invasion. A total of 1,012 aircraft, including 551 Lancasters, 412 Halifaxes, and 49 Mosquitoes, attacked 10 coastal batteries covering the invasion beaches. However, due to cloud cover, the success of these missions was limited.
By June 5, 22 out of 37 rail targets in occupied France were sufficiently damaged, and 15 were severely damaged, effectively crippling the Nazis’ ability to reinforce Normandy by rail. Bomber Command also conducted raids over areas like the Pas de Calais to reinforce the deception that the Allies were planning to invade this area.
Deception Operations
One of the key components of the Allied strategy was to deceive the Nazis about the actual location of the invasion. Bomber Command played a vital role in these deception operations, notably Operations Glimmer and Taxable.
Operations Glimmer and Taxable
Operations Glimmer and Taxable aimed to mislead the German forces into believing that the main Allied invasion was not happening in Normandy. These operations involved sophisticated tactics to create the illusion of invasion forces approaching different locations.
Operation Taxable, the larger of the two, involved 16 RAF Lancaster bombers from 617 Squadron. These bombers flew in overlapping circuits, dropping large quantities of “window” (strips of aluminum) at three-second intervals throughout the night, simulating an invasion force heading towards Cap d’Antifer, 80 km from Normandy. Eight bombers would be replaced by another eight seamlessly to avoid any suspicious gaps on the radar.
The “window” created a large blip on the radar, resembling a large fleet. Additionally, 18 small boats, including Harbor Defense Motor Launches (HDML) and RAF pinnaces, operated jamming equipment and simulated the radio chatter of a large fleet.
Simultaneously, Operation Glimmer involved six Short Stirling bombers, also dropping “window” while flying in circuits. This operation simulated a fleet approaching Pas de Calais. Twelve HDMLs (Task Force B) sailed under the window cloud, carrying jamming equipment, radios, and radar-reflecting balloons.
These deception efforts, part of the broader Operation Fortitude, lasted from midnight to 5 AM on June 6 and successfully misled the Germans about the real location of the landings.
Operation Titanic
Another crucial deception operation was Operation Titanic, which involved dropping dummy parachutists by four squadrons from No. 3 Group RAF. These dummies, nicknamed Ruperts, had explosives attached to them, designed to detonate after landing. The goal was to create the illusion of a paratrooper invasion, causing the Germans to believe that real paratroopers were hiding nearby.
Fireworks and sound effects were also used to simulate the noises of a firefight, further enhancing the deception. This operation added to the overall confusion among German forces, making it harder for them to respond effectively to the actual invasion.
Conclusion
Bomber Command’s contributions to D-Day were critical to the success of the Allied invasion. Through strategic bombing of German infrastructure, effective deception operations, and support for the airborne landings, Bomber Command helped to pave the way for the ground troops who would liberate Western Europe. The bravery and skill of these aircrews played an indispensable role in one of the most significant military operations in history.
