The jasta 2 and No. 19 Squadron reports agree their engagement took place in the afternoon. Thus, 5 “AM” in Richthofen’s combat report likely is a typo for 5 PM (if so, it is unknown if said typo originated on the German report or occured during translation).

Richthofen misidentified the pilot he shot down as No. 19 Sqn’s Ltn. E. W. Capper. Capper was actually shot down and killed on 14 April 1917 by Jasta 11 pilot Ltn. Kurt Wolff, his 15th victory. It has been theorized that Thompson possessed some article of clothing or flight gear that was marked with Capper’s name.
