‘ Operations Taxable, Glimmer and Big Drum Tactical Military Deceptions ‘

#AceBritishHistoryNews – D-DAY – June 06 – Operations Taxable, Glimmer and Big Drum were tactical military deceptions conducted on 6 June 1944 in support of the Allied landings in Normandy.

The operations formed the naval component of Operation Bodyguard, a wider series of tactical and strategic deceptions surrounding the invasion. By towing radar reflector balloons and producing significant amounts of radio traffic, small boats simulated invasion fleets approaching Cap d’Antifer, Pas-de-Calais and Normandy.

Royal Air Force bombers, including Lancaster bombers (pictured) from No. 617 "Dam Busters" Squadron, created the illusion of a large fleet on coastal radar screens by dropping chaff in progressive patterns. Glimmer and Taxable played on the German belief that the main invasion force would land in the Calais region.

Big Drum was positioned on the western flank of the real invasion force to try to confuse German forces about the scale of the landings. It is unclear whether the operations were successful, due to the complexity of their execution, poor weather, and lack of response from German forces.

It is possible they contributed to the overall confusion of D-Day as part of the wider Bodyguard plan.
