Citation 1: "During an intensive enemy air raid on an aerodrome, Sergeants Mortimer and Turner and Corporal Henderson remained at their posts and calmly carried out their duties. They displayed courage and example of a high order."
Citation 2: “This airwoman displayed exceptional courage and coolness whilst under attack, which had a great moral effect on all those whom she came into contact with. Her steadfast courage to both remain at her post whilst under bombardment and to undertake action to prevent further aircraft losses was outstanding.”
Mortimer received her MM from HM The King at an investiture held at Buckingham Palace in March 1941.
"In 1960 she sold her MM to a rag-and-bone man for 25 GBP but thankfully a military historian managed to organise a replacement for her."
