Captain Margaret I. Furey was a US Army Nurse Corps officer stationed at the 805th Medical Battalion. During the Battle of the Bulge, her field hospital lost power and heating in temperatures of -20°C. For 72 continuous hours, she performed emergency surgeries by candlelight and flashlight, with ether as the only anesthetic (often in critically short supply). She personally saved an estimated 40 men during that period. When asked about her experience decades later, she said: "You don't think about being scared. You think about the fact that the man on your table is someone's son." She retired as a colonel in 1965, having served in three wars. Her memoir, "Candlelight and Snowshoe," was self-published in 1978 in an edition of 200 copies. It was rediscovered in 2011 by a historian at Gettysburg College.
