According to the Des Moines Register, the wounded soldier's life was saved by Ludwig Gruber, the doctor in the enemy camp, despite not being eligible for any medical care, “Elmer should have died. He was an enemy combatant and not entitled to the same care and comfort as a wounded German’, or at least that is what the hospital's commanding officers told Ludwig. Ludwig ignored them. After a week, the US army came to collect the captives, and with the help of Richardson's negotiations, the two parties came to a truce, which ultimately saved many lives on both sides.
The doctor and the American soldier continued corresponding even after the war.
