"Evangeline" describes the betrothal of a fictional Acadian girl named Evangeline Bellefontaine to her beloved, Gabriel Lajeunesse, and their separation as the British deport the Acadians from Acadie in the Great Upheaval. The poem then follows Evangeline across the landscapes of America as she spends years in a search for him, at some times being near to Gabriel without realizing he was near. Finally she settles in Philadelphia and, as an old woman, works as a Sister of Mercy among the poor. While tending the dying during an epidemic she finds Gabriel among the sick, and he dies in her arms.
