Dear Paul,
I'm not doubting the story, I'm just not sure about the dating.
Here is what I came up with concerning Wold:
Ernest G. Wold, 1st Observation Squadron from 7/20/18 to 8/1/18, KIA 8/1/18...
Now August 1st must have been one BAD day; the 1st Obs. also lost Walter P. Miller (Lafayette Flying Corps) KIA; James J. Sykes KIA; and James C. Wooten, who died of wounds...
What happened?
The following is from Sloan's
WINGS OF HONOR (Schiffer, 1994); it's a caption for a really good modern drawing (unfortunately, it's in B&W, and, worse, I don't have a scanner):
"Artist Joseph DeMarco portrays a scene in the fierce battle of August 1st in which James J. Sykes and Walter P. Miller, 1st Obs Sqdn, were shot down along with James C. Wooten and Ernest G. Wold at around 9:15 a.m., all killed in action. [They're flying Salmsons, being attacked by Albatri, D5 or D5a; and the listing says, as noted above, that Wooten died of wounds-- Capt. Lewis] As the Allies launched the offensive at Chateau-Thierry the German Air Force brought up, in the words of the Gorrell historian, '...fighters, more fighters, and mostest fighters 'til they had us almost overwhelmed.' In this drawing, used here through the courtesy of the American Aviation Historical Society, Sykes and Miller are under attack by enemy Albatros fighters from, probably Jasta 4 or Jasta 6. Their accompanying Salmson with Wooten and Wold, were already downed and the 27th Pursuit Nieuports, [BTW, later Luke's squadron-- C.L.] assigned for protection reconnaissance planes that day, likewise suffered great loss. Of the 27th pilots from 'A' Flight, Clifford A. McIlvaine, Richard C. Martin and Arthur L. Whiton were shot down and made prisoner; Jason L. Hunt and Charles B. Sands were killed in action. 27th Sqdn called it their 'Jonah Day.' By August 6th the salient had been flattened by the advancing Allies and victory became a not too distant possibility. It was the turning point of the War."
