He was presented his MC by George V at an investiture ceremony at Buckingham Palace on 27 March 1919. His citation read:

With great dash he led his company forward into the enemy front line system, enabling the rest of his battalion to advance without severe casualties. He then organised bombing sections up a communication sap and trench and cleared them for the advance. At one strong point he led a small party against a nest of enemy machine guns, capturing two guns, and putting the crews out of action. He did very fine service.^[2]
