On November 22, 1942 the vessels are spotted by two B-17s and incorrectly identified them as destroyers roughly 68 miles southwest of Arawe. The B-17s made a first attack that was unsuccessful then circled around for a second bomb run when B-17E 41-2536 was hit by anti-aircraft fire and crashed into the sea with at least six of the crew bailing out. Hiyodori was undamaged during the attacks and rescues one of the crew. Afterwards, Hiyodori and Otori reach Lae, unload their and return to Rabaul on November 24, 1942.
The Naval Land Unit That Vanished In The Jungle by Tetsuo Watanabe adds:
"Hiyodori was on a sortie from
Rabaul to Lae, whose crew were in high moral and said 'Soon we
will show you a real man's war'. Their mission was not without incident, as a bombing attack by B-17's
that dropped bombs and circled around to strafe. Tetsuo's jaw was wounded
from a piece of shrapnel from a nearby blast, but was consoled by the
sight of a B-17 falling with its wing on fire. In a unique
turn of events, their ship picked up one of the Australian crew members
who survived the crash, and the author remembers "He caught a look at my face
bandaged except for my eyes, then he looked away" [likely, this was Australian Allan G. Fairfax]
