World War I record

Gassing was not usually considered a combat injury in WWI. In addition the Purple Heart did not exist as we know it today during WWI, soldiers would have worn a red "wound stripe"

It is possible to request a Purple Heart for WWI soldiers after the fact if you possess official military records which show that the soldier was wounded but for those who were gassed and whose record shows no injury I don't know.
