Military Cross (MC) Bar
T./Capt. Arthur Hicks Peck, D.S.O., M.C., R.F.C.
For conspicuous gallantry and devotion to duty. While patrolling at a height of 14,000 ft. he observed a formation of five enemy aircraft attempting a reconnaissance. He attacked the top machine, a scout, and drove it down out of control. He then attacked the second scout, which he also drove down out of control. He finally attacked a two-seater, and so quickly that he got to close quarters and opened fire with both guns. That, too, he sent down out of control. His performance was a splendid one, besides being costly for the enemy.
(M.C. gazetted 18th January, 1918.)

Distinguished Service Order (DSO)
T./Capt. Arthur Hicks Peck, M.C., Gen. List and R.F.C.
For conspicuous gallantry and devotion to duty. Whilst on patrol he engaged nine Albatross scouts, five of these being driven down, two of which he accounted for. On another occasion, whilst leading his flight on an offensive patrol, he dived alone on a formation of six enemy scouts, driving one down out of control. During the course of his patrol work he has brought down ten enemy machines, and his work on all occasions has been magnificent. He is a dashing patrol leader, and inspires all with the greatest keenness.
