Based on National Archive records, Joseph enlisted in the
army on Oct 14, 1942 in Boston, Massachusetts. However, this
record may represent a re-enlistment.
On November 25, 1937 he is listed as a Pfc in Battery
'D', Headquarters Headquarters Battery & Combat Train, Second Battalion,
Eleventh Field Artillery, Schofield Barracks, Hawaii.
It is possible that Joseph was discharged after
serving his initial enlistment and then was motivated to sign up again
after the declaration of war, especially given Japan's attack on a
facility he knew well, .
Cpl Gagnon was captured on October 31, 1944 and held
as a POW in Stalag 3C Alt Drewitz Brandenburg, Prussia 52-14.
According to National Archive records dated June 11,
1946, he was "Returned to Military Control, Liberated or Repatriated".
The actual release must have, however, occurred earlier than that date
and may represent a typo for "1945".
The actual place of his death and subsequent burial is
not yet known.
