William J. Guarnere Sr. (April 28, 1923 – March 8, 2014) was a United States Army paratrooper who fought in World War II as a non-commissioned officer with Easy Company, 2nd Battalion, 506th Parachute Infantry Regiment, in the 101st Airborne Division. Guarnere wrote Brothers in Battle, Best of Friends: Two WWII Paratroopers from the Original Band of Brothers Tell Their Story with long-time friend Edward "Babe" Heffron and journalist Robyn Post in 2007. Guarnere was portrayed in the 2001 HBO miniseries Band of Brothers by Frank John Hughes. Early life and education Guarnere was born in South Philadelphia, Pennsylvania on April 28, 1923. He was the youngest of 10 children born to Joseph and Augusta Guarnere, who were of Italian origin. He joined the Citizens Military Training Camp (CMTC) program during the Great Depression, gaining entrance at age 15 because his mother told the government her son was two years older. He spent three summers in the CMTC, which took four years to complete. His plan was to complete training and become an officer in the United States Army. After his third year, however, the program was canceled due to the war in Europe. Following the attack on Pearl Harbor, and six months before graduation, Guarnere left South Philadelphia High School and went to work for Baldwin Locomotive Works, making Sherman tanks for the army. This upset his mother, because none of her other children had graduated from high school. Guarnere switched to the night shift and returned to school, earning his diploma in 1942. Because of his work, he had an exemption from military service. However, on 31 August 1942, Guarnere enlisted in the military and started training at Camp Toccoa, Georgia. Military service Guarnere was assigned to Easy Company, 2nd Battalion, 506th Parachute Infantry Regiment, 101st Airborne Division. He made his first combat jump on D-Day as part of the Allied invasion of France. Guarnere earned the nickname "Wild Bill" because of his reckless attitude towards the enemy. He displayed strong hatred for the Germans as his older brother Henry Guarnere had been killed fighting in the Italian campaign at Monte Cassino. In the early hours of June 6, Guarnere joined lieutenant Richard Winters and a few others trying to secure the small village of Sainte-Marie-du-Mont and the exit of causeway number 2 leading from the beach. As they headed south, they heard a German platoon coming to
