In company with another pilot this officer recently attacked a hostile formation of fourteen scouts. One of these he shot down in flames, and a second out of control. Captain White not only displays courage and skill of a high order in attacking machines in the air and troops on the ground, but he has rendered excellent service on reconnaissance duty, obtaining most valuable information.
