Kennedy was given the task of converting shipyard dormitories into infirmaries in the hope that isolating the sick might help stop the spread of further contagion. The pressure on her husband was so great that he developed an ulcer - the first manifestation of the stress-induced stomach problems that would plague him all his life. In late October, the epidemic crested and a month later, the war was over.
