In 1914, he attempted to enter the army on August 16, and then again in October, but was refused due to poor eyesight. Banting successfully joined the army in 1915 and spent the summer training before returning to school. His class was fast-tracked to get more doctors into the war and so he graduated in December 1916 and reported for military duty the next day. He was wounded at the Battle of Cambrai in 1918. Despite his injuries, he helped other wounded men for sixteen hours, until another doctor told him to stop. He was awarded the Military Cross in 1919, for heroism. In 1918, he was awarded the licence to practice medicine, surgery, and midwifery by the Royal College of Physicians of London.
