I heard somewhere that the radios of the British Airborne Division did not work during operation Market Garden. An Officer who was there describes that he "...didn't know where anyone was...I didn't know the state of the battle." To what extent exactly did the British radioes flaw/malfunction during Operation Market Garden, and did they fail in any other such ways during other campaigns?
