September 2019 marks the 75th anniversary of Operation Market Garden, the allied attempt to create a sixty mile corridor, and secure a crossing over the Rhine. The plan was to use the newly formed First Allied Airborne Army to seize and hold nine key bridges until relieved by the British Army’s XXX Corp. The Airborne component was known as Market, and the ground attack was Garden. Joining me to talk about the background to airborne operations and Market Garden is Dr William Buckingham. William is the author or Arnhem: The Complete Story of Operation Market Garden 17-25 September 1944.
