"2nd Lt. Hervey Rhodes.
As an observer this officer has shown marked ability often under most difficult conditions. On one occasion when behind the enemy lines he saw a hostile balloon on the ground. He engaged and destroyed it from a height of 1,700 feet. On another occasion his machine was attacked by nine enemy scouts, which dived on the machine in pairs. He shot down three, one being seen to crash and two being brought down out of control. The remainder dispersed."
"Lieut. Croye Rothes Pithey, D.F.C.
2nd Lieut. (A./Lieut.) Hervey Rhodes,
D.F.C. (York. R.). (FRANCE)
Lieut. Pithey and his observer, Lieut. Rhodes, have crashed five enemy aeroplanes and driven down five out of control; in addition, they have shot down two balloons in flames, displaying conspicuous courage and skill on all occasions. On 1st September they attacked an enemy two-seater on contact patrol; this machine at first retired east but returned, accompanied by six scouts, to the attack; after a short engagement they were driven off, and Lieut. Pithey, although his machine was badly shot about, continued his patrol and brought back a most valuable and accurate report."
