"During the entire Airborne Operations at Arnhem 17th / 25th September, 1944, this NCO displayed the most outstanding gallantry. He acted as the RSM from the 21st to the 25th September. On the 21st and 22nd September, when the Battalion's armament was reduced to grenades only, Sergeant Callaghan collected and distributed vast quantities of German arms and ammunition which he obtained from No Mans Land in front of the forward defended localities. All this work was done in the face of practically continuous mortar and small arms fire. On the evening of the 22nd, his sector was relatively stronger in fire power than it had been immediately after the parachute descent. He also performed throughout invaluable work at the Regimental Aid Post bringing in many wounded under fire. His zeal, enthusiasm and undisputed gallantry all through the operation was magnificent and an inspiration to all ranks."
Recommended for the Distinguished Conduct Medal, but in its place was given the Dutch Bronze Lion.
