Honours and awards

  • 22 June 1918 - T/2nd Lt. Percy Jack Clayson, Gen. List, and RFC is awarded the Military Cross:

For conspicuous gallantry and devotion to duty. When on low-flying offensive patrol, he engaged an enemy scout and shot it down, with the result it crashed to earth. He has brought down several hostile machines, one of which was forced to land in our lines, and has engaged massed enemy troops and transport from a very low altitudes with machine-gun fire, inflicting heavy casualties. He has displayed the most marked determination, courage and skill.

— London Gazette[7]

A patrol leader of great skill, and a skilful marksman, whose personal fighting successes have proved of much value to his squadron. Captain Clayson's patrol frequently encountered enemy formations in superior numbers, but invariably succeeded in inflicting serious losses.
