The Hall of Valor Project - Arthur L. Post (photo, DSC citation)
"The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to Major (Air Corps) Arthur L. Post (ASN: O-439653), United States Army Air Forces, for extraordinary heroism in connection with military operations against an armed enemy while serving as a Pilot with the 6th Reconnaissance Group, FIFTH Air Force, in action against enemy forces on 28 September 1943, near Rabaul, New Britain. Major Post, in an unarmed and unescorted aircraft, voluntarily undertook a photographic mission over Rabaul. Although attacked by enemy planes, he completed his photographic run and, sighting an enemy convoy, photographed it also. After he had evaded the attacking planes with great skill for some time, and had sheared off the wing top of one of them, both his engines were finally shot out. He jumped from the crashing plane, and, to avoid being strafed, pulled the rip cord of his parachute at only 500 feet. Landing severely burned, with an injured leg, and in close proximity to the powerful enemy base, he contrived to find native assistance, and eluded enemy patrols. During a hundred days of hazardous jungle life, he assembled intelligence information which has proven invaluable in the assessment of enemy strength and in assisting the survival of Allied pilots in enemy controlled territory. Captain Post's unquestionable valor in aerial combat is in keeping with the highest traditions of the military service and reflects great credit upon himself and the United States Army Air Forces."

"1943- Major Arthur L. Post of Milwaukee, Wisconsin, was shot down on June 20th, 1943 and rescued on September 28th, 1943 after 101 days in the jungle. Here he is pictured here with Robert Doyle near the tail of a plane similar to his unarmed photo plane, "Limping Lizzie," that was shot down [sic, likely F-4 "Malaria Mabel" 41-2130 or F-4 "Limping Lizzie" 41-2156]. The airfield where this image was taken was located near Port Moresby, New Guinea (present day Papua New Guinea). Robert Doyle was not allowed to publish Post's story at that time. It was finally published in January, 1947, by the Milwaukee Journal. Major Post intended to write his own story, but was killed in a test airplane on August 25th, 1944, before he had the chance."
