The citation read:[5] Acting Wing Commander Percy Belgrave LUCAS, DFC (100626), Royal Air Force Volunteer Reserve Within the past few months this officer has led his fighter squadron a large number of varied sorties including escorts to bomber formations which have attacked enemy shipping with much success.

He has rendered most valuable service.After an imposed rest period on ground duties, "flying a desk", in December 1944 Lucas asked to be given charge of an operational squadron again.

He immediately resumed his practice of "leading from the front", which gained the respect of the highly experienced squadron air crews.

He was awarded a Bar to his DSO in October 1945 for making numerous attacks on enemy communications, often in appalling weather conditions.

After the war, he was encouraged to fight the 1945 general election as a Conservative and stood for Fulham West, where he lost to the sitting Member of Parliament (MP), Edith Summerskill, one of Labour's most prominent women in government following their landslide.

[12] There is a commemorative plaque at Prince's Golf Club, Sandwich by the 3rd tee on the Himalayas course which marks the spot where Lucas used his local knowledge of the course to make an emergency landing after his Spitfire was crippled over northern France during the war.

A golf tournament for boys and girls aged 8–13 years, the "Laddie Lucas Spoon", is held annually at Prince's.
