Unit Quotes:
What the horrors of war are, no one can imagine. They are not wounds and blood and fever, spotted and low, or dysentery, chronic and acute, cold and heat and famine. They are intoxication, drunken brutality, demoralization and disorder on the part of the inferior... jealousies, meanness, indifference, selfish brutality on the part of the superior" -Florence Nightingale
"[I] like the American soldier individually but do not like the nation as a whole. America entered the war for what money should could get out of it" -Frieda Fischer of Lohndorf, Germany, 1919
