During the Six-Day War, when Hadassah Hospital functioned as a field hospital, Saltz's academic, research, and combat experience was key in the treatment of the hundreds of wounded who packed the hospital's rooms and corridors. He took command, determined triage, chose the necessary surgical interventions, and prioritized patients. Through six endless days and nights, he never forgot a kind word for the wounded and their families, but asked nothing for himself – neither a cup of tea nor a moment's rest.[citation needed] The scene was similar during the 1973 Yom Kippur War, except that by then, it was his students who were manning the field hospital at Rephidim in the Sinai Desert.
