She posed as a Lithuanian nurse Rena Utinsky by obtaining obtained false papers and led an underground movement to smuggle medication, food, money, and other supplies to American POWs. She was imprisoned and tortured, but after being released, resumed her activities. Utinsky was known by the code name "Miss U." She is credited with helping countless soldiers although much of her story is not verifiable in any way other than her own autobiography, which contains some factual errors.
