"The Battalion of Death presents a new aspect of feminism which, while the wisdom and economy of its extension are consistently questioned the press is non the less serving the purpose of arousing its burning patriotic faith, something like shame in the men soldiers of Russia."
"The courage of the Battalion of Death when the actual test came is the subject of many enthusiastic Petrograd dispatches. They behaved splendidly under fire, penetrating into a first-line trench of the Germans and brought back prisoners."
